~ In-game description

The Archtiamat is a boss-sized fiend in Mobius Final Fantasy -- one of the four Arch-fiends and lieutenants of Chaos in Act 1, working as a larger and more powerful version of Tiamat.

The Archtiamat is naturally Immune to Stun (effect).pngImmune to Stun and Immune to Unguard (effect).pngImmune to Unguard.

At the beginning of battle, the Archtiamat casts Aegis of Discord to weaken you and apply a strong defensive barrier. This can be removed by breaking it, which will also restore its [WIND]Wind affinity. It also casts Tri-Barrier, which gives it some elemental protection from three of the elements. These can be broken down by casting spells of the opposite element at it, or waiting out the 4 turns until they expire.

Its attacks seem fairly simple, but they hit extremely hard... and repeatedly. Coupled with the Tri-Barrier protections, it's a formidable enemy and rightfully the strongest of Chaos' lieutenants.

In more difficult circumstances (like the Chaos Vortex), when the Archtiamat hits 50% HP, it will cast Wall (effect).pngWall on itself, giving time to repair its Break Gauge.

The Archtiamat gets 3-4 actions per turn.
