Trials of Nature
The embedded video jumps straight to the boss wave of the last level. The bosses are Chao, Brienne and Horghall. This was a relatively easy quest as long as you have a Melendor to heal your team. The rest of the quest is straight forward and can be completed using simple battle tactics. I packed Tiburtuses & Caedmons to color stack green and purple. Tiburtus debuffs the defense of the bosses and Melendor / Caedmon to remove Brienne’s buff. Start with taking down Chao if you have any purple heroes to take advantage to color stacked tile damage.
