imo, high damage NO mobility is trash in any roguelike, what's a roguelike you can name where you had literally no mobility options? Utilities and Hoppers help but that only goes so far. Maybe in combination with Engineer and Robot where you can just stand somewhere together with the fungus (huge group regen while standing still) you can create a deathball build

I don't think you'd go far solo as Artificer unless you got some godly ass mobility early, her damage is kinda of nuts though, and she can crit on top of it, her beam can easily just do 20k+ per rotation with a good enough build
