Almost Perfect Legendary IVs
This Cobblemon addon makes sure that every legendary or mythical Pokémon that spawns has three perfect IVs, with the rest being random.
About this Mod
Gives all legendary and mythical Pokémon exactly 3 perfect IVs on spawn. The other 3 IVs are randomized, so every encounter still feels unique. Designed to make legendary Pokémon more special without being too overpowered.
Fully server-side, no need for players to install anything.
Features:
- Legendary and mythical Pokémon spawn with 3 guaranteed perfect IVs
- Remaining 3 IVs are randomly generated for variety
- Affects all spawns
- Configurable in almostperfectlegendaryivs.json
- Change number of perfect IVs
- Override the default list of legendary/mythical Pokémon
Originally made for a private multiplayer server, but I figured others in the community might find it useful too.
