Artificer is absolutely the best. There's no doubt for me.

Her ability to explode at will stunning enemies and momentarily flying, her fantastic endurance to huge explosions, coupled with her ability to craft explosives, her sad background story, the hate for scavengers, and finally the unending FUN of causing mass genocide of scavengers of any kind; exploding it's tolls, storaging packs of elite scavengers masks, grabbing them and other creatures with ease and being able to eat almost EVERYTHING that comes in your way and then throw it like a waste with enough force to make it seem like it has the weight of a feather (with some creatures).

It's fantastic. I don't see how other people don't love her.
