Credit to Tonberry Troupe for their awesome infographics on Eald'narche
Since Eald'narche is fairly complicated as a character I thought I'd do a video covering his skill rotation.
He doesn't have a standard skill rotation and using Eald'narche essentially requires you to adjust your playstyle based on the boss mechanics and your party comp. However what's central to his kit is cycling through EX uses so that you get an EX ready by the time Terror expires.
Terror is the only reason why you should bring Eald'narche to the fight. If the boss is immune to terror or debuffs it's probably better to not use him.

Apologies this section will appear very small on Youtube. I should have used another format to showcase Eald'narche's skills.
