Its Special Rules alter the game in a brilliantly simple way. A simple to say concept, although it probably was not simple to code, that utterly changes the nature of Puzzle Quest, and makes a new game to discover. Cards that were extremely powerful (Mentor's Guidance, Secret Rendezvous, Brokers Charm) become useless, and cards that no one paid much attention to become monstrous game changers. Wizard Class withered and Paladin Class (now rotated out of Standard) became powerful.
The event has an entry fee of 20 Mana Crystals.
There is only one recharge, 23.5 hours after start time, which accumulates four charges per node, instead of the usual single charge every eight hours. It is impossible to lose charges by exceeding the maximum.
