The desiccated ents stood no chance against the hellhound because just getting close to it makes them take damage. The hellhound would just stand near a desiccated ent and it would immediately get caught in flames. Some even tried attacking as a group but the desiccated ents would just combust in flames because the hellhound would become the incarnation of hellfire.
Kanlaon is dealing with the lush ents using his mastery over two opposing strong elements. Kanlaon would summon frost using his new found powers for the ice element. Kanlaon would then use an intense heat wave to melt the frosted parts of the lush ents. This proved very effective as simple heat would not make the lush ents combust.
