Soulspheres as energy tanks is now based off a cvar, rather than DM/co-op. Been on too damn many co-op maps without megaspheres.
Frozen enemies last much longer, at least a minute before shattering. Ice Combos no longer guarantee frozen pain.
Ice Missile dramatically nerfed, no longer covers such a dramatically wide area or does so much damn damage. Player made slightly weaker to the Plasma Missile and the Ice Missile.
Speed Booster now has its own damagetype. Mook enemies are twice as vulnerable to it. High-class monsters are twice as resistant.
