The first massed public test of the new mechanics will be taking place on Wednesday, October 6th, at 8:00 p.m. EDT on the Warpstone test server. Tier 3 combat is on the menu, with templates provided for players who don't happen to have a character that fits the criteria. No word on whether or not participants will be eligible for prizes, but considering past test realm events, rewards for players seem like a distinct possibility. Warhammer Online players are encouraged to set some time aside for the Wednesday event and should prepare themselves for Warpstone access ahead of time.
