When you exchange kamas for ogrines at the DOFUS Kama Exchange (KE) or with the Kama Stone, the ogrines you receive will be linked to your account. This is also the case with ogrines purchased on Steam with real money.
Linked ogrines can no longer be used in the KE. However, they are still valid to buy subscriptions, items and services for games that accept ogrines.
Be careful, though, as ogrines obtained from the KE expire after 90 days, unlike those acquired via a Kama Stone or Steam.
These restrictions are necessary to avoid speculation on the Kama Exchange (KE) and keep the economy of your favorite games in good health!
