First time I fought this I got surprised by the adds. Pretty sure I killed them all but died due to the actual boss, thank god my homepoint was the same zone so I actually kept that map, then I went back and killed the Clops.

PLD solo I always take Alex maps as Sword Oath & Stoneskin at the start, for the Biclops I keep Fight or Flight & Circle of Scorn for the adds, throwing everything else at the boss. When the first set of adds pop I run over, FoF/CoS them, and tap a Mercy Stroke on one if it survives, then just go back to spamming the Biclops til FoF runs out(usually right after I CoS the 2nd set of adds). Toss in a Stoneskin & Bloodbath as needed(Bloodbath usually during 2nd adds just before CoS), and if really low pop Hallowed Ground>Convalescence>Curespam>Stoneskin just before HG is out

This map boss is laughable if you've got a melee & BRD/BLM/SMN duo, melee take the boss & ranged take the adds, and its easy as hell if you're bringing multiple friends who're all working on Nexus Light with you.
