Unique Light Tower - Arch Wizard

Name: Arch Wizard Cost: 7000 Attack: Vex Range: 3 Cooldown: 3 s Element: Light Gender: Male/Female Damage: 5-40 Lightning Magic: Every X attacks, cast a lightning bolt that chains up to 4 creeps, dealing 100% damage. Fire Magic: Every Y attacks, throw a fire ball at the target creep, dealing 200% bonus damage to creeps within 1 range. The scaling amounts could change, but I'm thinking X and Y could be around 3 and 5. This means his spells do about half of the total damage. This might mean the base damage needs to be reduced slightly to balance the tower
