Item acquisition
Supercharged Slam has restrictions on where or how it can drop.
Supercharged Slam now builds up stages slower but gains 40% more Damage per Stage now (from 20%). This may display as 20% still incorrectly until a later patch.
(Hotfix 6) Reduced the Damage of Supercharged Slam by approximately 60% overall (at maximum stages). This skill was unfortunately dealing far too much damage than intended given the short channel window required to hit maximum stages. The damage display text of this skill will be incorrect until we later do a client patch.
