I know we cant turn them into costumes yet but can i far the mats/plans? Like Ahon Kirus and Jarrets for example?

I have a jarettes Armour for dark knight since release of her. The plans for the jarette Armour must be stolen from a maid in heidel. I don't know her name now. If you klick on heidel the way point leads you to her boss. She is at the stairs inside the building. Google it

U need 2 plans from her l. The clothing and the plan for the Armour

Idk ahon kirus but I have a delphe knight armor for my sorc too the plan for delphe knight costume is a daily mission

They are indeed in the game, I have Ahon Kirus for witch.
