Are there any other items we can use on some corpses besides a blessed stake or obsidian knife?

Question

Aside from loot, skinning, and dusting when a creature dies sometimes we can use the corpse or use something on it's corpse to get an additional reward. For example, using a blessed stake on a demon we get demon dust. Are there any other items we use on corpses besides a blessed stake or obsidian knife? What can we get from using this item?

Answer 1

You can use Fishing Rod on dead Water Elemental. Using Fising Rod you have a chance to loot small emerald, small sapphire, white pearl, giant shimmering pearl and rarely - Leviathan's Amulet.
