Consume Soul was a skill that had a chance of inflicting instant kill. But by luck, Jack was under the buff of Gold Dragon Vitality, which protected the user from the instant kill effect. Still, with Jack's high luck stat, probably the instant kill would not be triggered even if Gold Dragon Vitality was not used.
Jack still received large damage from the attack. But due to his large health boost, he still got some to spare.
The hellion panther, which was originally pinned by the brave golem, was saved by Four Winds. His Titan Strength had a short cooldown and it was available again when Abasi was assaulting Jack. Four Winds activated it and turned his body into a giant. Although he was an expert martial artist, he wasn't confident enough to break through the blockage to get to Jack, so he instead relied on the Hellion Panther to go after Jack in his place.
