⚠️ This mod is currently adding compatibility with more bosses from other mods! If you want to add yours and update it to curseforge, join my discord for the poster template
Features

- Adds a Colosseum structure and an interactive Key Entity.
- When you right-click the Key Entity, it will spawn a random boss that you have already defeated at least once.
- The Key Entity resets every 1 real-life day (24 hours)
- If you do not defeat the boss within 24 hours, the boss will be discarded, and the Key Entity will reset without reward.
- A built-in UI displays a paginated list of available bosses (Press ` key to open)
- Custom boss entries can be added via datapacks.
- Resource packs can be used to customize boss posters shown in the UI.
