Hi
From Wiki:
Wrestling
When you strike a living target with fist weapon or unarmed attack you have 50% chance to reduce target's movement points by 8, action points by 3 and chance to hit with all ranged weapons by 7%. Stacks 5 times.
Specializations
Wrestling (10 levels) — Increases the chance to apply the debuff by 10% for each specialization point.
This means that you can get up to 150% chance to apply the debuff? That seems strange. I wonder if this is correct?
Edit: Seems like the last part of the post was removed, I try again.
