Before the fight
A short boss preparation checklist
Do not enter a required encounter with a damaged boat if the fight takes place on open water.
Consistency and safe range matter more than testing unfamiliar equipment during a progression fight.
Leave room for the named boss drop so it is easy to identify and carry back to the quest NPC.
A boss defeat may be followed by a pickup, hand-in, key, or vehicle interaction before progression completes.
