I have been trying to complete the quest, both solo with hirelings, and with a friend and hirelings. I can't take down Garos because of his Greater Command, Cause Fear and Hold Person spells. When I am free to fight, I whittle down his HP fairly well, but the spells greatly reduce the percentage of time I can hit him. I have 40, 27 and 21 on the Fortitude, Reflex and Will saves and have a Spell Resistance +20 item equipped. This combination gets me past the Malefic Seers in the quest, but is not enough to block Garos' spells. Can someone advise me on what to increase to give me a fighting chance?
