CastChaos, wait a little while. _L_ is making drown combos, so at that time, you can make this. No need to make it myself.
However, I don't want to give the flippers to the player right in the Light World... They would come only at Dark World Level 6... Still, it will be somehow.
I thought about a script which brings back died enemies. NOT especially whiches died, rather a set one. If it's an FFC you place it on a screen with 10 enemies and when one is killed, a new spawns. Obviously you don't want "Enemy => Secret" screen flag/rule here...
As an item, it spawns the specified enemies. Why? For training, for example.
I also thought about an item which draws HP from enemies and transfers it into Link. Maybe it's not possible to draw some HP frm enemies, but instantly killing one is possible. I think it's more than just a modification of your Destruction Machine item script.
(the only problem is that if I know that something is possible, then something such probably was already done...)
