Bushes - 25%

Loot Crates - 100%
Horizontal Barrels - 75%
Vertical Barrels - 75%
Pot - 50%

Exploding Pots - 100%
Spider Egg - 25%
Spider Egg (Rare) - 50%

Drop rates for breakables with more HP have been set higher than others because breaking them is more likely to require you to sacrifice some durability if you're hitting them with melee weapons.
