After beating story stage 18-40, you will unlock Crimson Abyss, where you can fight Urvaleppy for big amounts of level up materials. This game mode heavenly relies on summoners and can’t be beaten without them. The more units are on the battlefield, the smaller the push-back by Urvaleppy (otherwise you will be thrown down the cliff, which results in a defeat). A good line up should contain 3 summoners, 1 tank (each tank counts as 3 units) and 1 support. You get 3 tickets to fight in Crimsons Abyss daily and can buy more with diamonds.
Recommended heroes:
Sorvaley, Anpu, Daniel, Skooer&Hatty, Khalazza, Senway, Muka
