Tokens
Tokens are the ingame currency. You can use them to level up magic schools, buy spells, gear, and other items.
You get these by completing quests and defeating enemies. You also get a steady stream of tokens thanks to the Basic Magic Income which grants 1 dent per minute of ingame time. 1 dent is 0.01 tokens.
Tokens can only be earned in the game, not bought with real money or transferred between users.
