Cobblemon Battle Tower
A competitive battle challenge mod for Cobblemon. This mod is using a block as the source for the battle tower, not a specific world gen location, craft the holo battle tower to use it. Lock in your team, fight through progressively harder floors, and earn Battle Points to spend in the shop.
Battle Modes
- Singles — 1v1, 1–6 Pokémon
- Doubles — 2v2, 2–6 Pokémon
- Co-op Doubles — 2 players vs NPC, exactly 3 Pokémon per player
- Boss — Legendary boss encounters with a shared HP pool across all participants
- 1-player (6 Pokémon), 2-player (3 pokemon per player), 3-player (2 pokemon per player)
Progressive Difficulty
125+ competitive Smogon-inspired teams across unlimited floors:
| Floors | Gimmicks | Teams |
|---|---|---|
| 1–5 | None | 20 |
| 5–10 | Tera | 15 |
| 10–15 | Tera + Dynamax | 10 |
| 15–30 | Tera + Dynamax + Mega | 30 |
| 30+ | All gimmicks + Legendaries | 50 |
Item usage limits also increase with floor progression. NPC gimmick usage (Tera, Dynamax, Mega) can be individually toggled in config.
Team System
- Lock in your team before a run begins
- Team validation prevents mid-run swaps (species, held items, and abilities are all verified)
- No duplicate species or duplicate held items allowed
- Optional Random Team Mode — floor NPCs are assigned randomized Pokémon instead of structured trainer teams
- Optional legendary restrictions — allowing legendaries reduces BP rewards to 1 per floor
- Configurable banned Pokémon list
Boss Mode
Boss Mode pits you against a progression of Gigantamax Pokémon across 41 fixed floors. Every 5th floor raises the stakes with an epic two-phase legendary encounter — defeat the first form to trigger a dramatic phase transition into a more powerful second form, complete with a new battle theme and announcement. Beyond floor 41, bosses are drawn randomly from the full pool.
Phase boss lineup:
- Floor 5: Groudon → Primal Groudon
- Floor 10: Kyogre → Primal Kyogre
- Floor 15: Rayquaza → Mega Rayquaza
- Floor 20: Palkia → Origin Palkia
- Floor 25: Dialga → Origin Dialga
- Floor 30: Giratina → Origin Forme
- Floor 35: White Kyurem → Black Kyurem
- Floor 40: Necrozma → Ultra Necrozma
- Floor 41: Eternatus → Eternamax Eternatus
Battle Arenas
Configure custom arena locations in config.json. When arenas are available, battles teleport players and trainers to dedicated coordinates. Supports multiple dimensions. Falls back to the terminal location if no arenas are configured or all are occupied.
