Hi PIRI,
I don’t know if it’s normal but the raw damages calculation is : 2 Base, + xx% rogue power level, + xx% Might, + xx% weapon quality, +40% sneak attack (backstab not)
Right now, it’s a very powerful DOT : 4 damages / 0.3 sec / 15 sec = 195 raw damages.
If Hobble disappears before the end of DOT, raw damages are no longer considered as sneak attack (cf screen 2)
