The vampire infects clan castle defense reinforcements when attacking. It will make the clan castle reinforcements go against their own base for 30 seconds. After it had done so, it will go next to an enemy building and evaporate, dealing 80 hit point damage.
If there are no clan castle defense reinforcements it will only deal the 80 hit point damge to a building.
The vampire's infection radius is 3 tiles. It can infect ground and air troops.
If the vampire is on the defense side of the clan castle, it will infect the enemy troops deployed on a 3 tile radius. After it has done so, it will evaporate with no further damage.
The vampire will infect enemy troops when they have entered a 2 tile radius.
I hope you like my new idea for the vampire troop.
