RAID Masteries guide — build each tree around one job

A mastery page begins with the target mode

The same Champion can need different priorities in Arena and a long boss fight. Arena builds value an opening turn, immediate damage or control and effects that trigger from defeating enemies. Boss builds value sustained damage, reliable debuffs and survival over many rotations.

Choose the final mastery first, then trace a legal path that strengthens the same job. Do not mix attractive individual bonuses if their conditions rarely occur in the intended encounter.

Warmaster and Giant Slayer solve sustained damage

Warmaster generally fits attacks with one or two hits, while Giant Slayer rewards skills that strike repeatedly. The Champion's actual attack pattern matters more than the label “damage dealer.” These procs are especially useful against bosses, where a long fight gives them repeated opportunities.

Arena nukers may prefer a direct damage capstone, while a dedicated support can gain more from the Support or Defense tree. Read each current description before committing Scrolls because balance changes can alter exact values.

Accuracy and Turn Meter choices need context

Support masteries can help a debuffer reach an Accuracy target or extend effects. Turn Meter bonuses may be excellent in general play yet break a precise Demon Lord Speed tune by changing the planned sequence. Counterattack or cooldown effects can create the same problem.

For a tuned team, include Masteries in the calculation rather than treating them as free power. For an untuned progression team, favor consistency and the Champion's main job.

Finish one important Champion

The Minotaur provides Scroll progression. Focus runs on Champions whose long-term role is known so Scrolls do not spread across unfinished builds. The first Campaign farmer or Demon Lord core member usually creates a clearer return than a narrow reserve Champion.
