Trion Worlds has announced that they will be implementing a new collectible card mini-game to Rift as a part of the upcoming Nightmare Tide expansion, scheduled to be released later this fall.
The new resource-gathering, collectible card mini-game will be called Minions. The main goal of the mini-game is to collect minion cards and select adventure cards for the minions. Players will be able to send minions on adventures using minion cards. Adventures keep minions busy for a certain amount of time, and when that time is up, and the minion returns victorious, the player will receive loot. Once a minion earns enough experience from its adventures, it will level up and get better loot.
