Resourcefulness

Resourcefulness is a darkly funny mystery badge tied to the Volcanic Biome, sitting at a low 1-star difficulty and rewarding 5 diamonds. The secret action is grim: you must drop a dead teammate's body into the volcano's lava. It sounds brutal, but it is a scripted hidden interaction rather than a moral choice, and the game treats it as a one-off Easter egg.

The logistics are what make this fiddly. First you need a teammate who has actually died, then you have to be able to pick up and carry their body all the way to the volcano. Bodies are heavy and slow you down, so coordinate this with a friend who is willing to fall in battle, or grab a corpse opportunistically when one is already near the lava. The volcanic zone is a hot, hostile late-game area, so travel with healing and watch for ambient damage.

Because it only needs to happen once, the cleanest approach is a planned run with a co-op partner: have them go down near the volcano, haul the body to the lava's edge, and release it in. The diamonds drop the instant the body hits the molten pool.
