Introduction
Battle magic is not "cast the biggest explosion and hope the GM looks impressed." It is spellcasting under tactical pressure: formations, cover, morale, objectives, siege weapons, chokepoints, troops, and command timing.
Use this with combat spells, siege rituals, cantrips, Commander, Guardian, Wizard, skirmish warfare, troops and garrisons, and siege weapons and battle vehicles.

What Battle Magic Rewards
| Battlefield Need | Best Tools | Why It Matters |
|---|---|---|
| Troop damage ● | Area spells, splash damage, moving zones, repeated bursts | Troops are built around segments. Big single-target control is often the wrong hammer. |
| Formation protection ● | Dancing Shield, shield cantrips, cover, resistance, recovery magic | Keeping one front line alive can buy more actions than dealing one more packet of damage. |
| Terrain creation ● | Dividing Trench, Steel Fortifications, Frozen Fog, walls, difficult terrain | Terrain spells turn maps into decisions instead of wallpaper. |
| Siege support ● | Siege Weapon's Blessing, siege rituals, scouting, logistics magic | If the campaign has walls, crews, engines, or supply lines, this is not flavor. It is the encounter. |
| Morale pressure ● | Shock and Awe, fear effects, bard compositions, battlefield illusions | Frightened, stunned, and forced hesitation are brutal when enemies need coordinated actions. |
| Single-target non-damaging control into troops ● | Charm-style effects, one-creature tricks, narrow debuffs | This is where many casters waste turns. If the target is formation-scale, use formation-scale magic. |

Battlecry Spell Standouts
Battlecry's spell section is strongest when the GM gives the table battlefields, crews, fortifications, troops, ambush lanes, and strategic objectives. In a blank 30-foot room, some of these spells lose their teeth. That is not a spell problem; that is a map problem.
| Spell | Rank | Traditions | Best Use | Take |
|---|---|---|---|---|
| Shock and Awe ● | 5 | Arcane, occult | Wide morale hit with fear and stun pressure | One of the cleanest "the line breaks now" battle spells. Great when enemies need coordinated turns. |
| Siege Weapon's Blessing ● | 6 | Arcane, divine, occult | Supporting a mounted siege weapon | Fantastic in the specific scene it names. Dead weight in a dungeon crawl with no siege play. |
| Dancing Shield ● | 2 | All traditions | Protecting someone who cannot spend their own action economy on defense | The humble option that wins hard fights. Heightened use with Shield Block support makes it even more real. |
| Steel Fortifications ● | 2 | Arcane, primal | Instant cover, obstacles, and lane control | Low-rank battlefield geometry is better than it looks. Cover is not glamorous, but neither is being hit. |
| Dividing Trench ● | 3 | Arcane, primal | Soft-earth chokepoints, cover, and movement tax | Excellent when the map supports it. Weak on stone floors, polished halls, and other GM "nice try" surfaces. |
| Explosive Barrage ● | 6 | Arcane, primal | Spread-out clusters and troop segments | Fire plus sonic damage across multiple bursts gives it real battlefield shape. Watch resistances. |
| Frozen Fog ● | 6 | Arcane, primal | Zone damage, concealment pressure, speed penalties | Strong when the party can fight around it. Annoying when you also blind your own plan. |
| Helpful Reload ● | 2 | Arcane, divine, occult | Supporting reload weapons and ranged formations | It looks small until it fixes the one action the shooter could not afford. Best with planned ranged tactics. |
| Instant Minefield ● | 5 | Arcane, occult | Lane denial, ambush defense, gate approaches | Great when enemies must cross predictable squares. Poor when the battlefield is too open. |
| Blinding Bottle ● | 5 | Arcane, occult | Clustered enemies vulnerable to poison and blindness | The effect is nasty, but incapacitation and poison limitations keep it from being an always-pick. |
| Blister Bomb ● | 3 | Arcane, primal | Disease pressure and sickened against tight clusters | Good horror-war texture. Less reliable into disease immunity or short fights. |
| Boots on the Ground ● | 6 | Arcane, occult | Strategic deception with illusory troops | Not a combat damage spell. It is for scouts, commanders, panic, and battlefield misdirection. |
| Curse of Recoil ● | 1 | Divine, occult | Reaction defense against ranged attacks | Cheap, relevant, and easy to underrate. A good answer to archers, snipers, and firearm pressure. |
| Forced Mercy ● | 1 | Divine, occult | Captures, nonlethal objectives, stopping bleed pressure | Very campaign-dependent. Incredible when the mission says "take them alive." Forgettable otherwise. |
| Pest Swarm ● | 4 | Arcane, occult, primal | Flexible incarnate disruption | The value is in choosing the right swarm for the scene, not just dropping a weird spell because it is funny. |
| Skeleton Army ● | 6 | Arcane, divine, occult | Incarnate area damage and panic pressure | A solid battlefield spectacle spell with real area output. Best when enemies cannot simply spread out. |
| Holy Host / Unholy Army ● | 8 | Divine, occult | High-rank incarnate support or punishment | Strong in big scenes, especially when creature traits and sanctification matter. Know your campaign's enemies. |
| Conquering Soldiers ● | 10 | Arcane, divine | Legendary battle swing | The arrival punishes enemies, and the departure cleans up ally conditions while boosting the push. This is rank 10 doing rank 10 work. |
War Mage Package
The Wizard is the cleanest battle-magic chassis because Intelligence, preparation, broad spell access, and map control already point in that direction. Battlecry's War Mage class archetype makes the theme explicit: armor, shield support, war magic, a battle-magic school, and feats that reward area spells and battlefield support.
| Option | Why It Matters |
|---|---|
| War Mage Dedication ● | Area damage spells can reposition failed-save targets based on Intelligence modifier, which is exactly what a battlefield caster wants. |
| Intimidating Spell ● | Adding frightened pressure to area damage makes every failed save hurt twice. |
| Shield Spell Reinforcement ● | Pairs naturally with shields and Shield Block, especially beside a Guardian. |
| Shielding Formation ● | A focus spell that rewards allies for staying near the caster is exactly the kind of spell that makes battle maps matter. |
| Siege Ritualist ● | Great in a war campaign, unnecessary in a monster-of-the-week crawl. |
| Battlefield Arcana ● | Helps low-rank battle magic and cantrips avoid reaction punishment in contested spaces. |
| Mage's Field Dressing ● | Useful if you actually invest in Medicine. Otherwise it is a cute trick looking for a build. |
| Spellshield ● | Nice for shield-focused War Mages, but narrower than the repositioning and formation tools. |
Core Spell Staples Still Matter
Battlecry adds war-facing toys, but Player Core spell fundamentals still carry the table. The best battle caster keeps a mix of damage, control, protection, counterplay, and emergency recovery.
| Spell or Tool | Best Users | Battlefield Role |
|---|---|---|
| Courageous Anthem ● | Bard | The most efficient morale spell is often the one the Bard can repeat while everyone else spends real slots. |
| Bless ● | Cleric, Oracle | Status bonuses scale beautifully when the whole formation is making attacks. |
| Heroism ● | Divine and occult casters | Put it on the character whose turn decides the objective. Do not scatter premium buffs just to be polite. |
| Haste ● | Arcane and occult casters | Extra movement and Strikes get better when allies must reposition around lines, gates, hazards, or troops. |
| Slow ● | Arcane and occult casters | Removing actions from priority enemies is battle magic even when it does not look cinematic. |
| Heal / Soothe ● | Divine, primal, occult casters | Keeping the anchor standing is usually better than chasing one more damaged enemy. |
| Dispel Magic ● | Most traditions | Fortifications, invisibility, flight, magical zones, and enemy buffs all create problems damage cannot solve. |
| Revealing Light ● | Arcane, divine, occult | Ambush warfare gets much worse for the enemy when hiding stops working. |
| Darkness ● | Arcane, divine, occult | Strong with preparation and darkvision plans. A party that cannot see through its own trick deserves the result. |
| Resist Energy / Energy Aegis ● | Prepared casters especially | Better when scouting or monster knowledge tells you what is coming. |
| Fireball / Lightning Bolt ● | Arcane and primal casters | Still the honest answer to clustered enemies, troop segments, and creatures with bad save profiles. |
| Sure Strike ● | Attack-spell casters, War Mage | War Mage especially cares because the archetype can trade prepared magic into a timely accuracy tool. |
| Teleport ● | Arcane and occult casters | In war play, moving the right people to the right place can be more important than a combat turn. |
Class Fit
| Class | Why It Works |
|---|---|
| Wizard ● | Broad arcane preparation, Intelligence, area spells, counterplay, and War Mage support all point the same direction. |
| Bard ● | Compositions, occult control, buffs, and coordination make Bard one of the best "army feels stronger now" casters. |
| Cleric ● | Heal, Bless, protection, sanctified answers, and divine utility keep a formation standing. |
| Druid ● | Primal magic brings area damage, weather-adjacent pressure, terrain shaping, and recovery. |
| Sorcerer ● | Arcane and primal lean into blasts and control; divine and occult lean into morale, recovery, and debuffs. |
| Witch ● | Strong if the player treats the familiar and tradition as a planning engine instead of a spell-slot vending machine. |
| Oracle ● | Great battlefield moments, but the curse engine asks you to know when the fight is worth the cost. |
| Animist ● | Works well when apparitions and spell access are chosen for the campaign's enemies and terrain. |
| Commander ● | Commander tactics can turn allied cantrips, ranged attacks, shield use, and battlefield timing into bigger plays. |
| Guardian ● | Guardian makes protective magic better because the caster has someone worth shielding. |
Commander Tactics That Change Spell Value
Commander does not need to be a caster to make casters better. Battlecry tactics can let squadmates combine Trips, ranged damaging spells, shield reactions, ranged Strikes, and even certain cantrips inside coordinated plays.
| Tactic Interaction | Spellcaster Note |
|---|---|
| Ranged cantrip substitutions ● | Cantrips with enough range can participate in some ranged-volley tactics, so the caster is not sitting out the formation plan. |
| Trip plus damaging spell timing ● | The setup can be excellent, but slot or Focus Point use may come with a real next-turn cost. Use it for targets that matter. |
| Shield cantrip in formation defense ● | Mirrored shield-style play rewards parties with multiple shield users, shield cantrips, and actual positioning discipline. |
Siege Rituals
Siege rituals are for the campaign layer. They help the party prepare a settlement, assault a wall, move through hostile territory, preserve supplies, poison or protect siege ammunition, or shut down enemy magic. They are not substitutes for Fireball.
| Ritual | Best Use |
|---|---|
| Army of Shadows ● | Night assaults and approach cover. Darkness over a large area can make the battlefield feel like a battle instead of a hallway. |
| Oil-Slicked Walls ● | Defensive fortifications. Good when walls matter. Skip when the adventure has no climbing assault. |
| Secure Siege Weapons ● | Protecting engines and crews. A practical ritual for campaigns where siege gear is a real asset. |
| Reinforced Rations ● | Long campaigns and supply pressure. Logistics magic is boring until the GM starts counting food and water. Then it is suddenly heroic. |
| Plague Shot ● | Grim siege campaigns. Potent but ugly. This is the kind of tool that should match table tone and character ethics. |
| Encroaching Woods ● | Concealed approach. Strong for ambush movement and forest warfare. Less useful when the terrain cannot justify it. |
| Antimagic Artifice ● | High-level magical warfare. Magic suppression is a campaign-defining defense when enemy casters are part of the war plan. |
| Halt Death ● | Legendary battlefield survival. Rank 10 magic should change what armies fear. This does. |
Troops, Monsters, and Encounter Design
Battle magic needs real targets. Monster Core and Monster Core 2 matter because traits, saves, weaknesses, immunities, movement modes, and creature roles tell the caster what kind of spell is actually worth a slot.
When fighting troops, prioritize areas and effects that can touch multiple segments. When fighting elites, use knowledge checks, save targeting, and action denial. When fighting undead, fiends, constructs, plants, or swarms, check traits before trusting poison, disease, mental, precision, or vitality/void assumptions.
The GM side matters too. Encounter building, hazards, environment, and Victory Point-style objectives make battle magic more than damage math. A caster protecting a bridge, moving through fog, reinforcing a gate, or breaking a commander can win without topping the damage chart.
Staff, Wand, and Scroll Advice
| Item Plan | Use It For |
|---|---|
| Scrolls ● | Carry battle spells that are decisive but not daily staples: Filter Air, Forced Mercy, Instant Minefield, specialized detection, or siege utility. |
| Wands ● | Best for spells you expect to cast once per day in many adventures, such as defensive support or scouting utility. |
| Staves ● | A good staff should cover multiple battlefield jobs: defense, control, utility, and a damage fallback. |
| Consumable discipline ● | The best scroll is the one you bought before the siege, not the one you wished existed after initiative. |
See staves and wands, treasure by level, and equipment before turning the caster's pack into a museum of forgotten paper.
Common Mistakes
- Preparing only damage spells. Damage matters, but a battlefield also asks for movement, cover, counterplay, recovery, scouting, and morale.
- Ignoring creature traits. Poison, disease, mental, vitality, void, and precision assumptions can waste a turn if the monster profile says no.
- Using siege magic in non-siege adventures. A campaign-scale spell is not bad because it is narrow. It is bad when you brought it to the wrong campaign.
- Blocking your own party with fog, walls, and trenches. Control spells are supposed to punish enemies, not surprise your Fighter with a workplace accident.
- Forgetting cantrips. Battlecry Commander tactics and long fights make reliable ranged cantrips more relevant than "I am saving everything" caster habits.
Hot Takes
- Battle magic is best when the GM builds objectives. If every encounter is a flat arena, half the category is being asked to do clerical work in a boxing ring.
- Dancing Shield is more exciting than many blast spells because it changes who gets to keep taking turns.
- War Mage is not just "wizard with armor." The good part is moving enemies after failed saves and turning area spells into formation tools.
- Siege rituals are campaign promises. If the table learns them, the campaign should eventually give them walls, supplies, engines, and armies worth caring about.
- Against troops, the humble area spell is not basic. It is the point.
