Deathgaze (Record Keeper)

Deathgaze is a boss in Final Fantasy Record Keeper, fought in the Deathgaze Record of the Magicite Dungeons.

This version of Deathgaze is based on the Final Fantasy VI boss.

AI script
Deathgaze uses almost exclusively defense-ignoring dark attacks and piles of debuffs, such as Doom, Slow and Blind -- and actively lowers the Doom counts to tip the scales against the party.

A party of physical attackers is required, as all damage Deathgaze takes from magic and ninjutsu is reduced to 1/3.

After its first turn, Deathgaze will enter Dark Rage: in this state, it deals 20% less damage than normal, but all damage it takes is halved. After Dark Rage is interrupted, Deathgaze will re-enter on its second turn or when its HP is reduced by 10% since the previous entry.

If the HP thresholds aren't reached fast enough, Deathgaze will enter Phase Two after its 10th turn, Phase Three after its 20th turn, and will enrage after its 30th turn.

Strategy
All of Deathgaze's attacks ignore DEF and RES, so defensive buffs, including Protect and Shell, are out of the question.

Deathgaze's moveset is meant to stall the party until they're killed by the Doom timer, so the boss must go down quickly. Reraise is also out of the question, as Phase 3's Savage Doom removes that buff.

The Slowga spell on Deathgaze's third turn cannot be blocked with status resist accessories. Without an Astra source, it must be nullified with a well-timed Hastega spell or any source of party-wide Haste.

Dampen Light raises Deathgaze's holy resistance level by 2, which can be countered by one of Agrias's Soul Breaks or any other that can reduce a target's holy resistance.

The only way to counter Black Flurry is by bringing an Awakening, as the infinite ability uses granted by those Soul Breaks will negate Black Flurry's osmose effect.
