Pipe Dreams: Rune Fencer

[Duelle]

Whip Sword. Seven is the Rune Fencer from FF type-zero and her weapon is a segmented sword (like Ivy from Soul calibur) that she uses with Elemental lash type attacks and pretty much nails the aesthetic you're going for while also being a unique addition among FFXIV's current weapons. There'll also going to be an explosion of Quistis glams and other things.

I never played Type-0, so I had no idea that was a thing. I'll keep it in mind as I start doing revisions.

Speaking of which, some changes to the writeup:

Storm Runes: Stat increases buffed to 8% (so Unda increases direct hit by 8%, Flabra increases determination by 8%, Sulpor increases crit by 8%). Changed to effects to "runic attunements" that are independent of the runes themselves with a 40s duration (so if you pop Unda, you get a separate buff for 40s that indicates the 8% increase to direct hit). Subsequent runes activated extend the duration by 5s. In a perfect rotation, a 40s duration gives the player a two-GCD window to reuse a rune to fully refresh the duration, but the additional extensions give a bit of extra time in case you get screwed by mechanics or the boss becoming untargetable.

Havoc Runes: Stat boosts have been changed to be one stat boosted per element. Activating a Havoc Rune also freezes the duration of runic attunements. May end up just removing the stat boosts from Havoc Runes, but am still thinking about it.

One For All: Same purpose, different mechanic. OFA will activate all three Storm Runes at the same time as level 1 runes. Weaponskills used will level all three runes at the same time but gain their benefits at a decreased potency. Instead of weaponskills getting +60 potency from a single rune, they get +40 per active rune while under the effect of OFA (total of +120 potency). The corresponding rune stat increases are not penalized in potency or duration. Spenders register as consuming all 3 runes at the same time (so Runic Strike would deal 400 potency water damage + 400 potency wind damage + 400 potency lightning damage). OFA's cooldown is also reduced to 120s.
