Armor bypassed by acid and fire.
When crit by an attack not dealing acid or fire, a head splits, adding a d12 Hydra Head minion! Each minion moves with the Hydra, is destroyed only by acid or fire, and 1 minion can attack on the Hydra’s turn (once per round each). (A single AoE can only destroy half the existing minions in this way, in addition to damaging the Hydra.)
- •Quick Snap.
Move or Swim 6, then attack for 2d12 (Reach 3).
- •Storm of Jaws.
(2x) 2d12 (Reach 3). On hit: Grabbed (Escape DC 13).
- •Swallow Whole.
(Grapped Target Only) DC 13 STR or Swallowed.
At 75 HP, heads split, adding a number of minions equal to the number of players (as per Cursed Regrowth).
The Hydra is dying! 50 more damage and it dies. Until then, on each turn, it moves 6 and then uses Storm of Jaws.
Swallowed. You take 20 damage at the start of your turn. Your attacks cannot miss and ignore armor. A crit while swallowed severs a head, letting you escape but likely triggering Cursed Regrowth.
The hydra spreads out damage, trying to scare PCs away rather than killing them. It targets mostly tougher PCs, and waits at least a round before trying to swallow a grabbed PC.
The hydra focuses down weak characters, trying to swallow them as quickly as possible.
