CASSIO Shop Inventory & Prices in Speranza

Offers rotate weekly. Showing the wiki's listed week: 2026-10-20 to 2026-10-26. That week has ended, so in-game stock has likely rotated — the wiki is usually a few days behind. Treat this as the last confirmed rotation, not today's stock. Unlocks at Raider level 25 · added in 1.29.0.

What Cassio accepts

Cassio barters rather than selling for currency. He asks mainly for unique ARC materials, and sometimes weapons — Rare-only on high-tier trades, any weapon on low-tier. Weapon mods are not accepted and are stripped from anything traded in. Some weeks he also takes trinkets or other specific items.
