 * `"toughness"`: a value greater than 1 which represents the toughness of this payload, which measures how resistant it is to having its drop rate increased by [prospecting weapons](https://github.com/endless-sky/endless-sky/wiki/CreatingOutfits#weapon-attributes).

+Beginning with **v. 0.10.11**, minables can create [effects](CreatingEffects) while orbiting. You can choose an interval (in frames) between spawns. If `"relative to system center"` is set, the effect will face away from the system center (like a comet tail) instead of rotating with the minable.
