[MSEA] Targa and Scarlion bossfight

I liked both boss fights.
Targa is alot cooler looking for the battle.
My question is..
Where do the helms come from?
They have the same main stats as a zhelm and with the speed and jump I'd argue they are better for all classes except Warriors, Permas, and Brawlers (for the ACC).
Is the Foot etc. somehow related in getting said helms?
..
Also- I'd totally get those helms.
THEY LOOK AWESOME
