Introduction

Raid Quests are time gated, and require Masters to collectively defeat each boss a required number of times before the story can progress.
- For bosses that have multiple difficulties, it does not matter which difficulty is defeated, it still counts as 1 kill.
- Higher difficulties tend to have better material drop rates.
The unlock conditions and total kills required for each boss are listed in the table below.
