SO MANY IDEAS! in a way dd2 reminds me of playing around in the arr/hw/early sb sandbox of xiv where the emphasis was on worldbuilding and grounding its people and systems in relation to it- one primary thing I'm prob going to rip for him is casters, their outfits and how magic work in dd2.

I'll give a very specific example: for one of his canon xiv jobs, Red Mage- in lore it's never mentioned how RDM recovers aether (as opposed to all the casters save sage, they have lore explanations for where they drew aether from after exhausting it from casting) In DD2, Sorceror (the main class I played on Azem) uses Galvanise to recover stamina, their equivalent of MP- its a cast that locks you in to standing still while you concentrate to recover stamina. So I'm going to grab that idea for Arthur where he has to lock in to recover aether but instead of using the staff as the grounding point to recover, he'll use the RDM sword 👍 Ofc that'll leave him vulnerable to attacks but honestly that' just Caster Life (TM)
