Rules

Every event deals damage: by default a sub does 100 (Γ—2 for tier 2, Γ—3 for tier 3), each gifted sub 100, each Bit 1, each dollar tipped 100, a follow 10 and each raider 2. When the boss hits 0 HP, whoever dealt the final blow becomes the new boss at full HP. If the boss supports the stream themselves, they heal instead.

Example: a 1,000 HP boss takes a 500-Bit cheer (βˆ’500) and 5 gifted subs (βˆ’500). The gifter lands the last hit and takes the crown with 1,000 HP.
