This has been phenomenal! Soooo much utility in any competitive mode. Still playing with seal, pulse let's her get off the glitter effect on first attack.

Weapon: Arcane Laton. Better bouquet baton, but that base weapon is still decent. The key is "foe cannot counter attack" so you can get Miasma down safely.

Ice lock: we all know how amazing this skill is by now, but any of the second move skills can work for Lyn Ring set up.

Glittering Light: Quite important to set up safe follow up initiation, swinging a lot of match ups.

A Sway A/R: loads of stats and importantly wrathful effect. Alternatively, just use wrathful seal. Sway A/S might be better, but this came with Glitter from waz her name fodder.

B Preempt Amplify: Broooken new B for L'Arachal! Canto and damage support but still not as important as...

C Deadly Miasma! This is why flying staff is amazing unit type. SAFELY override terrain at range and strong mass debuff. Most important skill.

Lyn Ring is amazing, but Celica or others can work.
