To unlock Ultimate Viessa in The First Descendant, you need the following items:

Ultimate Viessa Enhanced Cells
Ultimate Viessa Stabilizer

Here’s how to get all the materials needed to research these items. We recommend using Sharen because of her stealth ability, which gives you a chance to obtain twice as many Amorphous Material Patters per run.

Ultimate Viessa Enhanced Cells

656 Flectoritef – Loot Resource and Munition boxes in White-night Gulch.
682 Hellion – Loot Resource and Munition boxes in Fortress.
76 Insulated Metallic Foil – Loot from monsters during Magister Lab and Slumber Valley missions in Kingston.
Ultimate Viessa Enhanced Cells Blueprint – Get Amorphous Material Pattern 56 from running Magister Lab on Hard, and then open it by fighting Executioner Void Intercept battle on Hard. There’s only a six percent chance for it to drop, so use a Shape Stabilizer.

There is only a six percent chance drop rate, so use a Shape Stabilizer to improve your odds.
