Steam Eruption

Steam Eruption

Buff
When killed, deals damage at the end of your next turn.
  • Steam Eruption is the Waterfall Giant boss mechanic.
  • Pressurize gives 15 stacks (20 on Ascension 9) and every other move adds 3.
  • When the Giant is killed it does not leave combat: its HP becomes effectively infinite, it spends one enemy turn showing a stun intent while it stores the stack count and drops the power.
  • On the following enemy turn it erupts for that stored amount and then dies for real.

Notes

Combat cannot end while it is in this state. The eruption is a real monster attack, so your Block, its Strength and Weak on it all apply. Killing it quickly keeps the number small; stalling lets it pile on 3 per turn. A kill on turn 1 still means two more enemy turns before the blast, so build Block for the second one.
