PF2e Creature Size Matters
PF2e normalizes damage across creature sizes — a Gargantuan dragon and a Medium fighter deal damage as if size is purely cosmetic. This module fixes that.
When a larger creature successfully hits a smaller one in melee, a GM-facing card appears in chat with:
- Bonus damage scaled to the size differential (fully configurable)
- Reflex save prompt with draggable condition links (Off-Guard, Prone, Clumsy)
- Critical hit doubling — automatic or manual GM choice
- Post to Chat — sends an inline save check players roll themselves with their own bonuses
- Apply Damage button — one click applies bonus damage to the target
- Treat Small PCs as Medium — removes size penalties for Small ancestries (gnomes, goblins, halflings, etc.), PCs only, enabled by default
New in 1.4.0: Size-Adjusted Encounter Level
An optional GM setting (off by default) that makes size count toward encounter XP and threat. Each opposing creature's level shifts by its size relative to the party's average size: Tiny −2, Small −1, Large +1, Huge +2, Gargantuan +3 against a Medium party. Small PCs count as Medium when Treat Small PCs as Medium is on.
- Changes encounter XP and threat only — actor stats are never touched
- Opposing combatants show a CSM: N marker in the combat tracker, with a tooltip explaining the shift
- Works with Elite and Weak adjustments, and with modules that use PF2e's XP calculator (such as Monk's Combat Details)
- libWrapper recommended but not required
All GM-facing by default. No player overhead. Full configuration via module settings.
