When wearing a Sarasha Gi, and wield a Black Xyston and a Copper Coliche, the player does not gain Sarasha Gi's effect (+12 crit/evade if the user is wielding weapons of the same type), despite the weapons in question counting as a Sword.

This also applies to Twin Dance, trying to twin dance a Coliche and Xyston doesn't work either!!!

This has just been a consequence of what the game looked at when determining the same weapon type, but I suppose it change, and has in 2.89 v3.
