pet-evolution
by nobody174
Pet Evolution is a NeoForge minigame mod in which players capture wild creatures, train them and evolve them through ten stages.
What it does
A Rune-Bound Vessel is the item used to catch wild creatures, and every captured pet keeps its own HP, Attack, Defense, Speed and Special values. Pets gain experience through battling, crafting, mining and exploring, and move up through ten evolution stages on each pet line. Breeding two pets together has a chance to produce a rarer offspring, so a lineage can improve over time.
Battling is handled by a Pokemon-style training system, and players can also challenge other players' pets in tactical battles. Each pet carries a rarity tier from Common to Uncommon, Rare and Epic, shown with color-coded tooltips. Pet stats and collections persist through logout and server restarts.
The mod is published for 1.21.1 only and needs NeoForge. Installation covers the server and each player's game. The source code and issue tracker are public, but the code is All rights reserved and not open source.
