This bug: 3.1 Charged Fireball staff doing no physical damage to Monks/Berserkers on shots that cleave still exists and is a huge problem for this weapon. 100% reproducable.
Steps to Reproduce:
Just fire up a game and throw some fireballs at a berserker type enemy (skaven or chaos). Works with mods spawning the enemies in keep or in normal gameplay. As long as you aren’t critting you’re getting no damage at all except the very minor DoT damage.
