New Evo Quest
Starting 21 March 15:00, new evolve material quests will appear in OPTS. The stages will be of higher difficulty than the current regular evo quest, but the drop rate of gold evolve cards will be higher as well.
Update: Bosses also have a small chance of dropping rainbow evolve cards.
These quests will be around only until 31 March 23:59, so make use of them while you can!
This post will be updated if more information becomes available.
