Escalation Tokens
A Pro farms the number of Escalation Tokens you pick on your account.
Escalation Tokens open the Escalation tiers in The Division 2. A stock of tokens lets you start any tier at any time, and the higher tiers are where Prototype gear drops.
Pick the number of tokens. A Pro runs Escalation on your account until they are in your inventory. The Prototype gear and every other drop of those runs stay yours.
Pick the amount, the platform, the boost method and the speed. In piloted play a Pro plays your agent. In self-play you stay on your account and farm with a Pro group. Piloted and self-play cost the same.
