I’d increase the number of tabs offline. For example, having 10 shared tabs, and 10 personal tabs per character.
And I’d have Mosaic spawn with :
100% chance to keep [random charging strike] charges on finishing move.
Finishing moves trigger charges only on their first hit.
It would replace the current 50% chance to keep charges on hit. The goal is to reduce the amount of effects, so I wouldn’t care if its damage was increased in some manner to compensate (and I also wouldn’t care if it wasn’t). Hell, I wouldn’t even mind using one copy on my assassin in order to combine a second charge type to its Phenix Strike if they made that change.
