Introduction
Summoned creatures are temporary tactical pieces, not bonus full characters. They add bodies, positioning, senses, damage types, flanking threats, reactions from enemies, and disposable hit points. They also cost actions, table time, and preparation.
That trade is the whole point. A good summon changes the encounter. A bad summon changes the encounter into one player's spreadsheet recital.
Summon Rules At A Glance
| Rule Piece | What It Means |
|---|---|
| Summon Trait ● | The spell conjures a creature, usually from a specified trait or category. Unless the spell says otherwise, the creature must be common and fit the summon limits. |
| Summoned Trait ● | The creature is temporary, gains minion rules, cannot summon more creatures, cannot create valuables, and disappears when the effect ends or it reaches 0 HP. |
| Minion Trait ● | The creature acts on your turn and normally gets only 2 actions when commanded. It generally has 0 reactions unless an ability says otherwise. |
| Sustain ● | A sustained effect lasts until the end of your next turn when you Sustain it. If a Sustain action is disrupted, the effect ends. |
| Immediate Actions ● | A summoned creature uses its 2 actions immediately when you finish casting the spell. This is why summon positioning matters before the spell lands. |
The practical loop is: cast the spell, place the creature in a legal space, take its first 2 actions, then keep paying the action cost on later turns if you want it to keep contributing.

Summon Spell Rank Limits
Player Core's summon trait table sets the maximum creature level by spell rank.
| Spell Rank | Maximum Creature Level |
|---|---|
| 1st | -1 |
| 2nd | 1 |
| 3rd | 2 |
| 4th | 3 |
| 5th | 5 |
| 6th | 7 |
| 7th | 9 |
| 8th | 11 |
| 9th | 13 |
| 10th | 15 |
Hot take: the table is the reality check. If a summon option feels like it would solo the encounter, you probably picked the wrong creature, misread the rank, ignored rarity, or accidentally invented a new career for the spell.
What Summons Are Good For
| Job | Why It Works |
|---|---|
| Blocking Space ● | A body in the right square can slow movement, protect a caster, obstruct a hallway, or make enemies spend actions. |
| Triggering Weaknesses ● | The right damage type, trait, or attack rider can matter more than raw numbers. |
| Flanking And Off-Guard ● | Summons can help melee allies create positioning pressure when the map supports it. |
| Absorbing Attacks ● | If an enemy spends a powerful action deleting a temporary creature, that may be a good trade. |
| Scouting Briefly ● | Duration, communication, senses, doors, terrain, and danger keep this from being free map hacking. |
| Replacing A PC ● | Summons are below party-member power and action-limited. Expecting a full teammate is how disappointment gets a stat block. |
Use flanking and positioning, movement actions, conditions in combat, and monster traits to judge which summon role actually fits the encounter.
What Summons Cannot Do
| Limit | Table Impact |
|---|---|
| No Summon Chains ● | A summoned creature cannot summon another creature. The game is not opening a tiny management company inside your turn. |
| No Value Creation ● | Summoned creatures cannot create things of value. This closes obvious economy abuse. |
| Costed Spells Are Blocked ● | A summoned creature cannot cast spells that require a cost. |
| High-Rank Spell Risk ● | If the creature tries to cast a spell of equal or higher rank than the spell that summoned it, that spell fails and the summon ends. |
| GM Adjudicates Commands ● | If communication is limited, the GM decides how well the creature follows detailed instructions. |
These limits are not flavor text. They are the difference between "cool tactical conjuration" and "one player now owns the encounter's accounting department."
Summons, Companions, And Familiars
Summoned creatures overlap with other extra-creature rules, but they are not the same thing. A summoner and eidolon have their own class procedure; this guide is for temporary creatures created by summon spells.
| Creature Type | How To Think About It |
|---|---|
| Summoned Creature ● | Temporary, spell-created, action-limited, and usually sustained. Great for a specific tactical job. |
| Animal Companion ● | A persistent class or feat investment with its own progression and a repeatable command pattern. |
| Familiar ● | A flexible utility creature, especially important for witch and several caster builds. |
| Mounted Ally ● | Uses mounted combat and command rules. Helpful, but it changes positioning and Reflex-save exposure. |
| Ritual-Created Minion ● | Some rituals can create minions under specific limits. These need campaign-level GM oversight. |
Player Core 2 expands the number of builds that care about companions, familiars, mounts, and battlefield bodies. That makes companions and familiars a required companion article for this one, not a cute optional detour.
Spell Tradition Notes
| Tradition | Summon Angle |
|---|---|
| Arcane ● | Broad utility and creature access. Wizard can lean into summon support when prepared for the right encounter. |
| Primal ● | Strong nature creature identity. Druid is the cleanest baseline for many creature-summoning expectations. |
| Divine ● | Thematic allies, spirit pressure, and support roles. Cleric, champion, and oracle care about faith, doctrine, and role more than raw body count. |
| Occult ● | Strange utility, mental pressure, and weird problem solving. Bard, psychic, and thaumaturge often care more about setup than attrition. |
Summon value changes by tradition because creature lists, spell access, and class action economy change. Do not copy a druid summon plan onto a wizard and expect the same rhythm.
Monster Book Use
Monster Core and Monster Core 2 expand the creature pool GMs can use, but not every creature is automatically legal for every summon spell.
Check the spell's creature category, the summon trait, spell rank, rarity, source access, creature size, traits, and table permission. New monsters are often better as encounter threats, patrons, ritual consequences, or story clues than as player-controlled summons.
That is especially true for complicated stat blocks. A creature with several conditional powers might be excellent for a GM and miserable as a mid-combat player summon. If running it slows the table, pick the cleaner option.
GM Table Control
Use summons generously, but control the procedure.
| GM Practice | Why It Helps |
|---|---|
| Ask For Default Summons ● | The player should have a short list ready before initiative. |
| Enforce Legal Space ● | The creature must appear in range, in an unoccupied space, and in a space large enough for it. |
| Track Sustain Clearly ● | If the caster does not Sustain when required, the effect ends at the normal time. |
| Keep Communication Honest ● | Detailed tactics require communication the creature can understand or reasonably follow. |
| Ban Stat Block Shopping Mid-Turn ● | Looking up twenty options while everyone waits is not strategy. It is a loading screen. |
GM Core's broader adjudication advice applies cleanly here: make a quick, fair, consistent ruling; keep the game moving; and review edge cases after the session if needed.
Player Checklist
Before preparing or casting a summon spell, answer these:
| Question | Good Answer |
|---|---|
| What job is this summon doing? ● | Blocking, flanking, scouting, soaking attacks, triggering weakness, movement utility, or applying a condition. |
| What is the action plan? ● | Know the casting cost, Sustain cost, and what your own turn looks like afterward. |
| Is the creature legal? ● | Check spell rank, creature level, trait/category, rarity, and source permission. |
| Can you run it quickly? ● | Have the stat block ready and pick two likely actions before your turn. |
| Does the map support it? ● | A huge creature in a cramped hallway may be a comedy sketch, not a plan. |
Common Mistakes
Forgetting the first 2 actions. The summoned creature acts immediately when the spell finishes.
Forgetting Sustain. Many summons disappear from relevance if the caster does not keep paying the action cost.
Expecting full PC output. Summons are lower-level, action-limited pieces. Their best work is often positional.
Ignoring communication. If you cannot communicate, do not expect elaborate tactical choreography.
Using illegal options. Creature level, commonality, traits, source access, and spell wording all matter.
Letting one summon eat the table. If the summon takes longer than the fighter's whole turn, fix the process.
