Almost Perfect Legendary IVs
by Goonta
Almost Perfect Legendary IVs makes legendary and mythical Pokémon from Cobblemon spawn with three perfect IVs, while the other three are randomized.
What it does
Each legendary or mythical Pokémon that spawns with this addon has three of its six IVs set to the perfect value. The remaining three IVs are generated at random, so each encounter still differs from the next. The change applies to spawns only, leaving Pokémon that players obtain by other means as they were.
The addon requires Cobblemon, which must be installed alongside it. It is a Fabric mod for 1.21.1 only, and it runs on the server side: only the server needs it, and players join without installing anything. Its settings are kept in almostperfectlegendaryivs.json, where server owners can change the number of perfect IVs and override the default list of legendary and mythical Pokémon.
Almost Perfect Legendary IVs was first published on 2025-05-30 and last updated on 2026-08-18, when version 2.0.0 for 1.21.1 was released. Its code is licensed under the MIT License, but the project is not open source.
