Terastallization is the Generation 9 battle gimmick — a Pokémon "Tera-types" mid-fight, swapping its battle type to whatever Tera type it's locked to.
Where Tera Is Allowed
- Open play — Terastallization is available in unranked battles, raids, and overworld encounters
- Ranked — Tera is disabled in the current season (see Ranked)
- Battle Factory — Tera Orbs are banned (see Battle Factory)
What's On the Server
- Tera Orb — the accessory that lets a Pokémon Terastallize once per battle
- Tera Shards — per-type shards (Fire, Water, Ghost, Dragon, etc.) used to change a Pokémon's Tera type
Tera Shards stack to 50.
How to Unlock
The Tera Orb unlock path on PBG is still being documented — check back here or ask in Discord for the current source. Once you have the orb, Tera works like any other Cobblemon mechanic: hold the Orb, pick a Tera type via shards, activate during battle.
Tera unlock path: needs verification. The mechanic is enabled and the items exist in-game; we'll fill in the canonical unlock once it's confirmed.
