Once you upgrade a tower to level 3, you unlock its special ability. Each type of tower has a unique offensive ability thaf doesn’t cost any gold or mana, but requires a cooldown period between uses. The more towers you have of a particular type (and the higher their level), the more potent the effect so think carefully when it comes time to upgrade and build more towers!

	Archer towers fire multiple bombardments of arrows. As you build more archer towers, more barrages will be added to this power making it even more deadly. If it doesn’t destroy the Wrorcs, it will at least soften them up!
	Fire towers produce an Inferno Strike which you can drag across the map, causing massive damage to anything it touches. You only have a limited time to play arround with it, so make sure you catch the most dangerous enemies currently on the paths.
	Ice towers have a skill that buys you a lot more time and works best in tandem with a lot of towers. The Deep Chill blast covers a huge area on the map and stops any Wrorcs in their tracks, giving you more time to shoot them down before they reach the gates or escape.
	Nature towers overgrows their vines, strengthening them and adding a poison effect to any enemy unlucky enough to trample over them. Add some fire damage and slow-down to the poison on the Wrorcs and you won’t even have to hit them to take them down!
