Demon Avenger is a Resistance Warrior class that deals decent damage.
Skill Wheels
Auto-Battle
Demon Avenger’s auto-battle wheel is one of the simplest. Just use Exceed: Execution for mobbing and Nether Shield for additional damage. Putting Execution and Nether Shield on preset will help you clear the map faster. Exceed: demon Strike helps your demon avenger move around the map faster. Blood Prison and Thousand Swords (lvl170 hyper skill) provide AOE attack.
Bossing
Exceed: Execution is your main bossing skill too. Again, setting up a preset with Execution and Nether Shield will save you time during bossing. Nether Slice provides boss debuff. Blood Prison stuns bosses.
