So, I'm sure you're all dying to know lol, it's out.
Hammer and chisel didn't have any effect. Continued with mole grips which just scuffed the head as they kept slipping. Tried hammering bigger Torx and Hex in, didn't work. Couldn't fit bolt extractor on with the clutch cover being so close. Then finally found a use for those imperial sockets lol, 1/2" socket smashed over the head well enough to start undo-ing it.
