Vital Spark

Buff

ALL Skills are Tainted 2.

Only the Infested Prism elite, which fights alone, carries this.
It starts with 2 stacks (3 from Ascension 9) and its Pulsate move adds 2 more (3) each cycle.
At the start of the fight every Skill in your combat deck is marked Tainted at the stack count, and Skills created later get the mark too.
Playing a Tainted Skill applies that many stacks of Tainted to you; each stack adds 1 damage to every enemy Attack hit on you until the end of the enemies' turn.

Notes

When the stack count rises, every marked card updates at once. Killing the Prism clears all marks. Artifact blocks the Tainted debuff but not the marking. The debuff is per hit, so the 3-hit Whirlwind (5 damage, 6 from Ascension 9) punishes it hardest; spend Skills before Jab or Radiate, not before Whirlwind.
