Gimmicky solo Melee Crab build help

[Maris]

So, one character of mine I've really been enjoying playing has been a petless, melee-oriented Crab Spider. I realize, obviously, this is extremely suboptimal as far as min-max, but eh, she's fun and I'm working on a Crabbermind as well.

I'm not necessarily looking for something super tanky, just a build that'll afford her a fair deal of survivability and resistance as she plunges into the heart of packs of enemies and AOEs them to death. 

... Also, as a side note, on her current build I've honestly been having pretty good experiences with Cross Punch, of all things. 

Any and all help would be appreciated, thanks!
