Strategy
A party of magic attackers is required, as all damage Belias takes from physical attacks is reduced to 1/3.

Belias is a far easier boss than most other 5★ Magicites, as Demonic Flame, Savage Painflare and Berserk always hit the same party slots. His only real gimmicks are Saber, which can be countered by ATK debuffs like Power Breakdown and Exhausting Polka; the two-slot Berserk that can only be blocked by an Astra source; and Greater Barrier, which should be dispelled depending on the player's damage output.
