[SPOILER] So Ilberd..

[Vejjiegirl]

Red lotus, a discontinued Gladiator skill from 1.0, was fire element, but npcs still use this ability.

So... probably not. Most likely not infact.

People keep saying its Red Lotus, but the animation for Red lotus in 1.0 is nothing like the attack illbred used in that cutscene.
The Skill Red Lotus was even used for another mob attack in Bahamut Coil, so the whole attack was probably reconnected.
