It was slightly challenging, but got through it better than expected with the Bounty Hunter, Witch, Druid, and Beast Master.
Trained a couple Mountain Apes to help defeat some creatures in the line while the Druid's Owl also helped attack.
It was a mental challenge because I don't have the optimum skills equipped so had to do some serious thinking to solve this puzzle and take of the creatures in line with the least amount of damage.
Onto the final expedition of this realm. Unlocked the Monk for future use!
