Pillars of Eternity II: Deadfire · Class ability
The Shield Cracks
The Shield Cracks lowers a target’s armor rating by two, with its duration increasing as the target takes damage.
How it works
The ranking passage calls The Shield Cracks an offensive Chanter invocation. It lowers the target’s armor rating by two, and the duration increases as that target takes damage. The author says that in boss fights this can amount to a nearly permanent -2 for the fight, but that is presented as an assessment rather than a guaranteed duration. No invocation cost or exact duration is supplied.
