Piercing strike

① Piercing Strike (per-encounter free reaction ✦ [[strike maneuver]]) spear fighting style
Trigger:	You hit an enemy with a spear.
Effect:	Subtract the damage from the target’s armor defense instead of applying it to the target’s hit points; this damage remains until the armor is repaired. Each point of damage reduces the target's armor defense by 1. You may not reduce the target’s armor defense below their adjusted reflex defense; excess damage is applied to the target’s hit points as normal.
