Using Fei as Lead and Ultor with Angel Idols, I could pass this quest. Ultor taunts the Life Taker ultimate attack and survive with Angel Idol. With Fei as Lead when Post-Graham does the BB drain and HP to 1 ultimate attack, some of your unit will get instantly healed to 100% HP (due to 40% chance of recovering 20% of 999,999 fixed damage) and also you can make Graham kill himself with the damage reflection (20% chance to reflect 20% damage). After he revived he did his ultimate attack, I just had to finish him with normal attacks, he just committed suicide himself lol.
