Just to get straight to the point, azoth vials are going to become more and more irrelevant. Eventually I think weapon respecs will be free and with azoth consumption on teleports reducing; we will have a mass abundance of azoth vials.
I propose making tier 3, 4 and 5 azoth vials to give them a use.
Vial of Suspended Azoth (T3): Select a perk for a craft.
Vial of Potent Azoth (T4): Select 2 perks for a craft.
Vial of Concentrated Azoth (T5): Select 3 perks for a craft. (If 600, third perk fails if 599 and below)
Keep RNG the same for 595-600 and be able to select all 3 perks to give crafters an incentive to craft and reduce price of BiS gear from 200k to roughly what a T5 Azoth vial would cost.
Bi-product
Refine them at an Arcana station, vials would no doubt go up in price, but if you had 5 vials to craft Potent Azoth and an additional 3 to make a Concentrated Azoth vial, that would make 15 TO vials per craft. Even at the current price that’s 200 gold per craft, let alone when everyone buys it up. So BiS gear wouldn’t be too easy to make, but they would for sure be costly still.
15 Vials = 750 Azoth
