Corrupted abbot is a long range enemy. He can be destroyed easily but he has the attack, three beam attack of from his Skull Headed Stick.if you want to destroy the Abbot easily, choose long range heroes like the Warmage and Sentinel. be careful, if you are low level like level 9 you wont win. If he teams up with the other corrupted abbots he is tough as ever. if you are about lv14, you will pass the level easily.
-Dont let him team up with other abbots
-Use a Tier 13 or 13+ like the Rebel Rod of the warmage.
-Well, it depends on you-try yourself!!
