Of course, the Forest Elves and their arrows were not omnipotent.
After several barrages their position was exposed and the fire was returned, quite literally.
The Heart of the Blazing Lion army unleashed fierce flames. They conjured fireballs, firespears, and various other projectiles and threw them back at the Forest Elves. Most fiery projectiles were not that fast, but their overwhelming number and destructive power were more than enough to force the Forest Elves to retreat.
The Untamed Jungle caught fire. Everything was about to burn down.
Lilica and the others retreated. However, they didn't run away from the battle. They trusted that the Lesser Water Elementals and Lesser Earth Elementals would do a great job extinguishing the flames. In the worst case, the Lesser Elementals would restrain the flames for a while.
