2. Prison of Darkness, Disaster Help

Having some serious problems with Ragnarok Prison of Darkness, Disaster. Level 81 using light team 32518 attack with 11 skill for light damage. Using -35% ATK and -30% DEF debuffs on boss and give team Ailment RST and Ailment removal but can only seem to deal ~500k-1m damage before party is wiped out. Every other team is about the same power wise and the other Elements Bosses I can deal ~3 million damage. Am I doing something really wrong or is this one supposed to be this hard?
