Planar Wanderer 5e — Is a Feat With No ASI Worth Taking?

Introduction

Planar Wanderer is the odd one out in the Scion of the Outer Planes feat chain. Every other 4th-level follow-on feat this book adds — Agent of Order, Baleful Scion, Cohort of Chaos, Outlands Envoy, Righteous Heritor — opens with an Ability Score Increase before listing its other benefits. Planar Wanderer doesn't. It trades that stat bump for three narrower, portal-focused utility benefits instead. That tradeoff is the entire question this guide answers: is a feat that skips the ASI ever worth an Ability Score Improvement slot.

What the Feat Does

Prerequisite: 4th level, Scion of the Outer Planes (any plane).

Planar Wanderer grants three benefits, and none of them is an Ability Score Increase:

Planar Adaptation. When you finish a long rest, choose acid, cold, or fire. You have resistance to that damage type until you finish your next long rest.

Portal Cracker. As an action, concentrate on a portal within 5 feet that you're aware of and make a DC 20 Intelligence (Arcana) check. Success: you force the portal open or closed for 1 hour, and it stops responding to its own portal key unless someone using that key beats a DC 20 Intelligence (Arcana) check as an action. Failure: 3d8 psychic damage, and you can't try that specific portal again until your next long rest.

Portal Sense. You always know the direction to the last planar portal you used, as long as you and it remain on the same plane. As an action, you can also detect any portals within 30 feet that aren't behind total cover — once per long rest.

For how portal keys and portal quirks work, and what Portal Cracker is actually overriding, see the Planescape guide's portals section.

Why the Missing ASI Matters More Than It Looks

An Ability Score Improvement slot is one of the scarcest resources in a 5e build — most classes get five across an entire campaign. Every other feat in this book's chain treats that slot as a baseline you don't give up: you get the +1 (or the option to boost two scores by +1 each) and then the feat's unique benefit on top. Planar Wanderer breaks that pattern. You're comparing three situational utility effects against a permanent stat increase that compounds for the rest of the campaign — better save DCs, better attack rolls, better skill checks, forever.

That doesn't make Planar Wanderer bad. It makes it a feat you take for the utility specifically, not as a default "well, it's the next feat in my chain" pick the way you might treat Agent of Order or Righteous Heritor.

When Planar Wanderer Is Actually Worth It

● A portal-heavy Planescape or Sigil campaign

If your campaign's core loop involves finding, opening, and navigating portals — which a Sigil-based campaign almost certainly does — Portal Cracker and Portal Sense stop being situational and start being weekly-use tools. A party without a spellcaster who has plane shift, knock, or similar options especially benefits from having someone who can force a stubborn portal open without hunting down its key first.

● A character who already has their ASI needs covered

If you're playing a build where your primary stat is already capped at 20, or you took your key ASIs earlier and this is a spare late-campaign feat slot, the opportunity cost of skipping an Ability Score Increase drops sharply. In that situation, Planar Wanderer's utility is close to free value.

● A build still chasing a capped primary stat

If your primary ability score isn't at 20 yet, weigh Planar Wanderer against just taking the +2/+1 option instead. A Fighter or Rogue who still needs Dexterity or Strength points will usually get more from those points than from Portal Cracker's occasional utility, unless the campaign specifically revolves around portal navigation.

● A campaign with little to no portal content

Outside Sigil and the Outlands, portals are rare enough that Planar Wanderer's three benefits go mostly unused. If your Planescape arc is a short side-trip rather than the campaign's spine, this is a weak pick relative to almost any other 4th-level option.

Comparing Planar Wanderer to the Plane-Locked Follow-Ons

Every other follow-on feat requires a specific plane choice from Scion of the Outer Planes and grants an ASI plus a combat-relevant benefit: Agent of Order's Stasis Strike (extra force damage and a potential restrain), Baleful Scion's Grasp of Avarice (necrotic damage plus self-healing), Cohort of Chaos's Chaotic Flare (randomized bonus effects on a natural 1 or 20), Outlands Envoy's free misty step and tongues, and Righteous Heritor's Soothe Pain (a strong defensive reaction). All five of those read as combat or exploration force multipliers with a stat bump attached. Planar Wanderer reads as a toolkit for a specific kind of problem — you don't have a portal's key — and nothing else. That's a narrower pitch, but it's also the only follow-on that doesn't care which plane you picked for Scion of the Outer Planes, which makes it available to every character in the chain regardless of earlier choices.

Common Mistakes

Taking it as a default "next feat" pick. Because it's the universal follow-on with no plane restriction, it's tempting to grab automatically. Check whether your campaign will actually use Portal Cracker and Portal Sense before spending a slot that has no stat payoff.

Forgetting the failure cost on Portal Cracker. A failed DC 20 Intelligence (Arcana) check deals 3d8 psychic damage to you and locks out a second attempt on that portal until your next long rest. This is not a safe fallback option — treat it as a real gamble, not a guaranteed unlock.

Ignoring Planar Adaptation's daily choice. The resistance is chosen fresh each long rest from acid, cold, or fire. Plan your choice around what you actually expect to face that day, not a fixed default.

Verdict

Situational, not a default pick. Planar Wanderer is worth taking specifically for a portal-centric Sigil or Outlands campaign, or for a character whose primary stat needs are already satisfied elsewhere. For everyone else, the missing Ability Score Increase is a real cost that the three utility benefits don't reliably offset. Compare it directly against your campaign's actual portal content before committing a feat slot with no stat payoff attached.

FAQ

Does it really have no ASI? Yes, confirmed against the source text — the two sibling follow-on feats in the same section both print one explicitly, and Planar Wanderer doesn't.

What plane do I need for Scion of the Outer Planes to take this? Any of the five — it's the universal follow-on.

Is Portal Cracker good without a plane-shift caster in the party? Yes, that's its strongest use case, at the cost of a real risk of 3d8 psychic damage on failure.
