Completing the Isabella quests gives you, in a row of cache;
STR Weapon set + Amulet → DEX Weapon set + Ring → INT/FOC Weapon sets + Earrings → STR Armour set → DEX Armour set → INT/FOC set
So you for sure have gotten it since what you show in your post is the final pieces of the rotation
Saul Goodman, keep spamming it and see if it pops up again
If you want Named Corrupted sets, there are some you can grind in the open world but they are better for portals, or just buy from the market if you’re not poor like me
My crafting isn’t high enough for the gear and it just isn’t profitable enough to justify spending 150-200k to level it. I get the estimate from profession calculators using my servers market price
Heavy Tempestuous Set is STR
Med one is DEX
There is also Isabella gear set
As well as few other dropped sets
all from Tempest
Tempestuous sets can be received from that quest on entrance ,not sure if they changed it but on release you could get that box from 7 quests afterwards you only got gypsum
Tempestuous sets can also be received as drops from mobs in Tempest …all of them except Isabella’s set ,pieces of which are dropped only by her.
Just a side note - I wish they just dropped the box gear at 600. It’s very easy to make the mistake of salvaging it. Usually stuff with a generic name like “___ of the Soldier” can’t upgrade at 600. This set is extremely useful for new or returning players to get into mutations more easily.
Not only the armors, the weapons can also be made legendaries. Salvaged any Tempest cache due to misleading naming except the Heavy STR and Medium DEX, because I wanted to try M1 and you need +600GS for that.
You can spam the quest indefinitely, but the rewards are random as hell, and only one per cache: Gypsum Orb, Tempestuous Weapon/Armor, Umbral Shards (around 200~400).
