I don't know about you but it really seems weird of a few things:
*Deadly Shard Bomb is made of Crimsonite and in turn, Crimsonite is highly related to Fire.
*Deadly Charcoaler despite being a reskin of the Deadly Crystal Bomb shoots out red shards. Not Green like the Deadly Crystal Bomb.
*The Description states that "it'll char the competition" despite not actually inflicting Fire.
*Normal Damage is rubbish on the Deadly Shard Bomb. Fire would at least give it a good reason to use it.
So, yeah.
+1.
