Lightning hound

This will send a limited number of lightning bolts to destroy the destined target. When the lightning hound uses all of the lightning bolts it will explode into twice as many lightning bolts as the first time. When you upgrade the lightning hound it will be more over powered. This will also be a dark elixer troop.

Wheres the hp?movement? jumps walls? damage?

If you can take a th with just this troop and 5 lightning spells then it is OP. If it cannot even do that with 240 troop space then it doesn't do damage worth mentioning. Stupid idea
