Found a two bar corner hd combo with Ryo that does 865 damage, pretty neat.
j.D, s.D, f.A, HD, s.D-qcf.A, srk.C-hcb.D, srk.A-hcb.D, srk.C-2xqcf.A+C
I've seen similar posted, but this one seems so effective i thought i'd post it just in case.
Forgot to mention but you can change the ender to just srk.C-qcf.A f,b,f.A for 696 (i think) damage. Fantastic new alternative for me, though i don't know if it will work all too well online hehe.. Nothing wrong with the simple loops though.
