Necros has normal cst spd,low dmg.
but he has good and many curses...the bad is that without good m.atk there arent many chances for cursed to be successfull.so a good necro has to have overenchanted gloom.and when he do it on the enemy there are more chances for the curses to be successful.also,he has always to have a pet out and the transfer pain have to toggled.
