– Enemies and soldiers with armor receive less physical damage. That means that they receive more damage from magic towers.
– Support Barracks with ranged towers to maximize enemy exposure. Your soldiers should fight in the range of your towers that deal damage.
– Reinforcement are a great way to split enemy forces.
– Artillery works best against high concentration of enemies. Tesla towers near a graveyard will make sure that no skeleton will pass.
– Artillery damage is highest in the center of the explosion.
– Use reinforcement constantly to slow and damage the enemy. If the enemies come from two lanes, put the reinforcement on the start of a lane. Your towers/hero will have to deal with only one wave of creatures at the time.
– Always aim rain of fire a little ahead of your target. This spell is very valuable for the final maps.
– With the Salvage upgrade you can sell archer towers with only a 10% of loss. Pretty useless.
More tips and tricks
– Flying enemies cannot be blocked by Barracks, and won’t be targeted by the most artillery. Best way to deal with flying creatures is to have the hunter hero and barbarians upgraded to throwing axes. But for an early game, an upgraded tower with archers and the hunter hero should be fine.
– Enemies with magic resistance receive less damage from magic attacks.
– Adjust the rally point of soldiers to create better strategies. If you have two groups of soldiers, try to put them together so they will have the same range of engaging in attacks. To set the rally point, use the blue flag.
– Sometimes it is better to build more towers instead of upgrading a few. I’ve finished the game mostly by playing with upgraded towers and it works.
– Poison damage ignores armor. Partially useful. If you have the gold, upgrade to poison attacks.
– Upgrading a Barrack, instantly train new soldiers.
– Calling an early wave gives bonus cash and reduces the spell cooldowns a bit. If you just sit idle for a few seconds, tap the enemy circle icon to call the wave.
– Artillery explosions can damage flying enemies although they cannot target them directly. Great upgrade for artillery towers.
– Use Barracks or reinforcement to isolate troublesome enemies. You can build a barrack at the start of an enemy lane in order to slow them down.
– Earth Elementals are very tough and deal area damage every time they strike. Best way to deal with these is to have some melee + hunter hero. Also the mage tower that teleports enemies back are very useful as the earth elementals are moving very slow.
– You can check the incoming wave of enemies by tapping the wave icon once. Most of the time you won’t have that luxury time to spare.
