just leak fucking melee already
Allegedly twitter says that it will be a katana of some sort.
It will probably be the overdrive blade's VFX + the cleanness of the RGX blade in one, topped off with the kill-based crystal effect within the blade.
Being the highest kills in the lobby will create an emanating glow of golden aura from the blade, just like the overdrive blade shows off electricity when unsheathed.
Inspect animation will hopefully be custom but even if its not it should look very clean.
Katana is the cleanest out of all the other options anyway, hopefully they confirm it to be one.
Chained blades (like kuronami, unlikely as that is relatively recent)
Axe (boring as fuck)
Fan (on a champs melee tierlist this one would be comparable to the kunai)
Prelude Sword (Would go pretty hard)
Mace similar to cryostasis melee (Idk about this one)
Fist (Power fist, altitude melee-esque; lame as fuck)
Origin / Chronovoid melee (Honestly would go pretty hard)
