A garbage-can-sized gnome canister meant to air-deploy a live boss on a target — but this one's rusted mechanism fails.
The Altitude-Based Deployment Device is the egg-shaped, garbage-can-sized canister the Gnomish Drop Bear drops on Carl's party — designed to pop open at altitude and unleash a live boss like the Feral Goose. This one is so rusted it never opens, splattering its boss instead and landing as a dented dud marked "This Item is Broken." Intrigued by its altitude-fuse dial mechanism, Carl pockets the whole shell for study.
A garbage-can-sized metallic egg with a clear seam like an Easter candy egg and an altitude-based dial fuse; dented and rusted.
