Hard to Kill

Hard to Kill

Buff
Reduce all damage taken and HP lost by Exoskeleton to 9.

Every Exoskeleton enters with 9 stacks, and the stack count is a hard ceiling on any single instance of damage or HP loss it suffers. A 30-damage hit becomes 9; a 5-damage hit stays 5. Each hit is capped on its own, so many small hits get through where one big one does not: three hits remove up to 27, one giant swing removes 9.

Notes

Multi-hit Attacks, Shivs and per-trigger effects such as Juggernaut or Hailstorm are worth far more here than a single loaded strike. The Hive Exoskeleton fights field several at once, 24 to 28 HP each (25 to 29 on Ascension 8+), so budget at least 3 capped hits per bug. Poison still ticks under the cap as long as each tick is 9 or less.
