Wukong's Journey stages feature a new Mechanic, the Five Elemental Holders, which correspond to the five Chinese elements of gold, wood, water, fire and earth. Strategically placing towers near them can turn the tide of battle, as each holder grants unique buffs:
Gold : Extra gold + reduced fees
Fire : Damage bonus + single target instant kill
Wood : Increased range + Slowed down enemies
Earth : Life bonus + summon soldiers
Water : Heal allies + teleport for a distance
Together, the Five Elemental Holders add a deep layer of strategy, choosing where and when to harness their powers could make the difference between victory and defeat!
