I was looking at the entry for Stalker Spines power Ripper.
http://coh.redtomax.com/data/powers/power.php?id=Stalker_Melee.Spines.Ripper (http://coh.redtomax.com/data/powers/power.php?id=Stalker_Melee.Spines.Ripper)
It contains this passage:
85.08 Lethal Damage (10% chance) if ((source kMeter < .9) and ((target is held) or (target is asleep)))
What is kMeter? I don't know what this means.
i believe it's the variable for the "Hidden" status
*edit*
and which is used to calculate critical hits, i think
(kritikal meter?) :)
kritikal is just a cooler way to spell critical :P.
