I'm looking to step up my all-round climbing game ever closer to mutant status

Learned on a recent trip to Yosemite that I need to step up my hard slab/offwidth/stemming game (got d*ckslapped/shutdown real hard, it hurt good) to get closer to accomplishing my ultimate purpose in life so my training focus for the meantime will be those.
Here thee, I ask you great RRG wizards, what does my future hold for hard slab/offwidth/stemming dihedral on future trips to the red?
(especially anything that's really technique/skill intensive, please, have mercy and bestow upon me your gracious knowledge
