Well that's some news. Curious where this will take MXL, but congrats regardless. Passion projects turning into something that contributes to real job and life experience is many people's dreams. Maybe one day I'll be able to play a MXL standalone spinoff. There had better be goblins and rainbow rods.
Cain's TP in Tristram can be used as a regular TP. Seems like it's random and doesn't always happen. Game had no other players, (Please don't actually fix this.)
Have you tried A1 Rogue merc? Deals nice aoe damage that makes use of neph spirit very well, and bear stance keeps her alive most of the time. Ranger uses Arrowside which is a huge boost to single target damage.
