New classes added (on the Throne of Darkness): DeathKnight Lord (daily farming quest for mem), Chrono Assassin (1% drop rate quest item, but can be repeatable) Daimon (which can be bought at baconcat), Eternal Invertionist (Rank 10 Eternal), and lastly, Scarlet Sorceress (farm-able in the Tower of Mirrors)
You can probably mess with undiscovered glitches or exploit in-game. (I don't exactly know what it will be) Since the only newest feature they had is the HeroMart Points.
But goodluck to you and hope you contribute more to the community.
