I love how everyone is talking about all of these things and forgetting that... Yang kind of just Skillfucks to hell and back, and nothing Steve does beyond an Ender Pearl can actually get him out of arm's reach of Yang cause his movement speed is shit and nothing he has for movement is faster then the equalized combat speed, and Yang has this very nasty tendency to schmove in combat via various sources.
Hell she could even DASH to Steve and there wouldn't be shit he could do about it.
Now let me go through Steve's list of shit to throw at the wall.
Melee: at a skill disadvantage Melee is the worst thing Steve could ever go for and will get him unceremoniously murdered.
TNT: Takes eons to go off, a non-issue.
ALL splash pots: Yang has a forcefield around her at all times, so uh, liquid isn't doing much
Bow: Ranged weapon which takes a bit to charge and Steve outright ******* scales to dodging it at point-blank. non-issue.
Blocks: Yang has about 900 different ways of going up. Non-issue.
Trident: if used its lightning and whatnot could cause a problem, but uh, it's pretty slow. And nothing Stops Yang from catching it mid-air and using it ON Steve.
Ender Pearls: these things CHUNK Steve for just under 30% of his entire life bar, so he's got one at max to use safely.
Totem of undying: so uh, yeah. Second life bar. Sure would be unfortunate if the first one posed any challenge whatsoever anyway- oh right its incap only so non-issue.
