Sloane is the vendor in Destiny 2 that deals with Arcology rep. She is located on Titan near the Siren’s Watch landing zone.
When trying to grind out Reputation for Arcology Engrams it is wise to obtain and use a Ghost that will reward you with additional Arcology Tokens upon discovering other Arcology Tokens.
Sloane accepts Arcology Tokens, Alkane Dust and Alkane Spores in exchange for reputation points. 20 Tokens will be required for a full level of Reputation. It will take about 100 Alkane Dust or 20 Alkane Spores for 1 full level of Reputation. Once you have handed in 20 tokens, 100 Alkane Dust, 20 Alkane Spore or any combination of the three you can collect your Faction Reward which will show in her menu as a Legendary Engram. You can get one or more of the following items from each engram you collect from Sloane:
- Faction Helmet (Class Specific)
- Faction Gauntlets (Class Specific)
- Faction Chest Armor (Class Specific)
- Faction Leg Armor (Class Specific)
- Faction Class Item (Class Specific)
- New Pacific Rush Shader
- New Pacific Sink Shader
- Faction Fusion Rifle: NOX Echo III
- Faction Hand Cannon: Annual Skate
- Faction Pulse Rifle: Swift Ride
- Faction Rocket Launcher: Hoosegow
- Faction Sidearm: Dead Man Walking
- Faction Submachine Gun: Foggy Notion
- Faction Sword: Negative Space
- Legendary Shards
- Misc armor pieces and weapons in a shifting lootpool
You can check the exact stats of the items or what is currently in the shifting lootpool by pressing or on the Faction Reward Engram while speaking to Sloane.
