Gilgamesh’s balanced deck and Charisma skill allow him to work well in a lot of teams. These small shortcomings prevent him from being a completely overpowered unit, but since they’re clear-cut and easy to compensate for, he is easily one of the best in the business.
A bit of external aid is needed in order to maximize Gilgamesh’s performance, both in the form of defensive measures as well as critical stars. His primary weakness is his lack of survival or utility skills, which makes him unsuited for slower-paced teams.
Additionally, Gilgamesh is armed with the Archer class’s high star absorption, further increased by Collector EX, as well as the Independent Action passive skill, making him a highly reliable critical damage dealer to boot. After his NP upgrade, this bonus damage is notable enough that the NP is often compared in effectiveness to single-target NPs, while its damage to non-Servant enemies is still more than respectable. The biggest contributing factor to its awesome power is the NP’s bonus damage against all but a few Servants, and Servants often account for most of the harder fights in the game. An offensive powerhouse with good stats across the board, Gilgamesh’s main value lies in his signature NP, Enuma Elish. In recognition of his worthy Master, the King of Heroes’ magnificent strength has been unleashed in all its heavenly glory. 'Now awaken, Ea! A worthy stage has been set for you!'
