Describe the bug
So when you kill a goose with an item in its beak it will drop that item. However killing a Goose with an item in its beak with ANY Skyroot weapon results in the item being duped. (You get 2 of the same item)
All the Skyroot weapons has a special enchantment/effect that when you kill a mob it will drop Double the drops. Regular weapons with looting does not reproduce this Dupe because its looting enchantment is different.
To Reproduce
Have/get a Skyroot Weapon first

1. Spawn a Goose or find one in the overworld.
2. Drop any item.
3. Let the Goose pick up item.
4. Kill the Goose with the Skyroot weapon.
5. It will drop 2 of the exact same item from what you dropped earlier.

Expected behavior
You get a free item copy

Info (please complete the following information):

• Modpack Version: 3.0 Beta 2.
• Server or Singleplayer: Singleplayer in the video but I am sure it works in servers too.
• Version the world was created on: 3.0 Beta 2

Additional context
This should also work on rebirth of the night version 2.77 or any version with the Goose (better animals plus) and Any skyroot weapon (any skyroot weapon that spartan weaponry adds).

Thanks for this report. We'll have to remove Skyroot weapons honestly since they allow for duping boss drops. We can add it back in the future if the Aether devs decide to give us more config options for the ability.

Does this work with skyroot tools?

Does this work with skyroot tools?

it shouldnt. All skyroot weapons have the "Double the drops" effect so it should just be the weapons, unless there's a skyroot pickaxe, which I couldn't find.

Fixed in a4d2b02 by removing skyroot weapons
