05 Dmg (Weapon)

[05] yeah no this doesn't seem to be used; not even by charge. it's just Dmg_(weapon) but it doesn't have accept elements. - Talcall, for a third time

Notes

As Talcall said, No routines jumps to this one (not in battle.bin - or it's done via a jalr command)
This routine jump to a dedicated Physical evasion routine without "the weather effects on bows part". Which seems to be dedicated too(only linked to this one).
