This bug causes damage dealt to Link by script-generated Lwepon bomb explosions, when "Link`s bombs hurt Link" quest rule is turned on, to be measured in FULL HEARTS, rather than usual 1/4th of heart as intended. So an explosive from scripted Lweapon, with default Z1 Lweapon->Damage = 8, can kill default Gibdo (HP=14, bomb defense = none) in 2 hits, yet dealing 8 full hearts in damage to Link, he wouldn`t be careful enough, as deadly, as Super Bombs. Yet at the same time, Eweapon bomb explosion with the same Eweapon->Damage value does only 2 full hearts in damage (8/4=2). No armor rings used in testing.
Scripted Lweapon bomb explosions and "Link`s bombs hurt Link" quest rule issue
It's not a bug; they work that way for compatibility with older versions. It is something that should be configurable, though.
