Its already september. That leaves October, November, December then end of the year. I have just joined the game again when jorm was launched so i missed the first 2. How far apart are they spaced? Will it be at the end of the faction war?
December
We got Black Prior the 31 January, Hitokiri the 2nd May, Jormungandr the 1st August. Following this logic and according to warriors den schedule we should get the Wulin heroe the 31 October.
