Promise Drops

Each run, mobs can drop around 15 collectible upgrades. Gathered upgrades grant temporary bonuses, such as refilling saturation or health. The chance of a drop depends on the mob type: hostile mobs have a 25% chance, passive mobs 5%, and special cases such as Iron Golems drop their upgrade with 100% chance. Baby mobs add a further 5% to the drop chance of their respective type.

The Upgrade Drop Chance upgrade raises global drop chances by 5% per level, up to a maximum of 50%. Death Face is a late event that appears only in multiplayer. Once one player is left standing, a timer of roughly 60 seconds starts before he arrives. When he gets too close, the run's upgrades are replaced with skill points, and the cycle begins anew. The mod is designed for cooperative play, and the author recommends it.

Files target only 1.21.11, with 1.0.4 as the latest Fabric build, released on 2026-02-21 under the MIT License. The source code is public, and the mod is open source. It is also noted to work with the Rougecraft data pack as an addon, though the author describes that pairing as a use the mod was created with, not a formal integration.
