On Elevation, hate level 7 is changed into a lockpicking bonus instead of a damage increase.
In the process, devs appeared to have changed the increased damage factor from 1.5x to 0.0x instead of 1.0x
Meaning that, in effect, activating the lock picking bonus makes you COMPLETELY unable to do anything in melee combat. I have not tested ranged combat.
So basically, when you're in the middle of PvP and trying to activate hate level 9, you're clicking only a few pixels away from a 'certain death' button.
How to reproduce:
Give yourself Hate level 7 on Elevation and some fancy weapon, then try to attack a young hen. Watch yourself fail.
This results in some pretty hilarious combat logs, the following happened with an 80+ql enchanted metal spear, >70FS and >70 spear skill
