Additional Info

Sunder Armor works by ignoring 25% PRP (physical resistance percentage) of the enemy. So the final damage is multiplied by (1-Max(0, PRP-25%)) rather than (1-PRP).

Note that Sunder Armor DOES NOT change the PRP of the enemy. It only let heavy attacks, including Rend, ignore part of the PRP (25% on level 5). So there is no way that light attacks will benefit from this skill.

Since a wide range of monsters have PRP, this skill is very useful against them. However, nearly no human or non-human enemy has PRP.
