Leveret

Grew up under the oak without making a sound, and has heard you coming for a while now.

A pet. It is kept on your profile rather than in your bag, so it cannot be sold, banked or lost, and it can be found again. Every find is told in the world's chat.

What drops it

Rolled on its own on every kill, rather than from the loot table, so it takes nothing away from anything else that falls off it.
