It is simple: create an extra dungeon on Lord of Light.
The enemies:
- wave 1: one golden son of each class;
- wave 2: one newborn of light of each class;
- boss wave: one lord of light of each class (that part could be to hard to new players, so need ajustment).
The loot:
- colorless evo shards;
- colorful xp shards.
That way, there is no need to create new toons, making easier to do, I guess.
