I agree with you. Chester Droors is not a good opponent. The three on one battle is almost impossible to deal with alone. If you attempt to summon a minion you may easily run into a problem. The cheat. Chester droors is not too difficult to deal with alone, but with three on one battle it makes every turn very valuable because they could each cast a one pip attack which is about 100 damage each. That's 300 damage every turn and the cheat makes you cast a trap at some point which is a valuable turn, and 300 health wasted!
place a trap on hmi and he stops cheating. Make sure to use a trap from a school other than yours so you dont clean it off. Elemental or Spirit traps are a good idea so you can use the one from your school and leave the others floating around him
What I meant was to rebattle him, I've already beaten him. I thought he was pretty easy, but I want to try to farm him. I can't respawn him for some reason. So could someone help?
