Decayed Whale Blubber

Decayed Whale Blubber can be fished up from the Great Sea around the Broken Isles, as well as from Black Barracuda Schools; it has an increased chance to be caught by using an Arcane Lure. It can also be purchased from Impus for.

When used, it will be placed on the ground, which will attract flies; these can be looted to receive the Ravenous Fly. The fly allows one to catch Ancient Black Barracuda. If it is used after having obtained the Underlight Angler, one will instead be able to catch Ancient Black Barracuda.
