Skeleton only drop bones and arrows

...what else are they supposed to drop?
monsters will only drop their equipment if the kill gives them xp.

when you use a trident killer(which gives xp)killed mobs don’t drop their equipments

I could of sworn that I had a farm a while back and the bows kept filling my chests but y'all are right and this was my own stupidity

Mobs only drop equipment (such as bows) when killed by a player’s mele attack. That it must be a mele attack is an issue tracked at MCPE-44408. That it must be a player’s attack is by design.
