XA * YA Calculation

No Parameters - Returns nothing

Load Current Ability XA and YA and Store XA * YA as Target current action HP Damage
Enable Target current action Type HP Damage flag

Note : past this routine, any change of XA or YA will be pointless (this is why oil doesn't work as intended in vanilla)
