Ever wanted to punish players for dying over and over to bosses? Feel like it's easy to cheese a boss because players can just respawn infinitely to eventually kill a boss?
Look no further! Boss Ultimatum solves that by adding a very customizable config that allows you to add "ultimatums" to bosses.
These ultimatums define how much health the boss should heal. A percentage of its max health? A flat amount? Or remove the boss so they have to resummon it?
Features
- Maximum Health Healing
- Flat Value Healing
- Minimum Deaths to trigger ultimatum (Fabric only)
- Per-Difficulty Setting (e.g. Only on hard)
- Remove boss intead of healing
- Health gains before ultimatum (e.g. Heal the boss 10% of their max health but 100% after ultimatum that can have a minimum of deaths)
