Decrepify Against Immune Monsters

Decrepify lowers physical resistance by 50% at every level. Against a physical immune monster (100% or more) only a fifth of it applies, -10%, so Decrepify breaks physical immunity up to 109%. Once a Sunder Charm has broken the immunity, the full -50% applies, where Conviction and Lower Resist stay at a fifth (the game's states.txt marks the curse sunderfull).
