Add a new Spell

Add a spell like Bomb Spell. The thing it does is that once dropped, the affected troops will go underground and target defenses and will blow up, reducing the defense's hit points by quarter. This is more like Jump spell but it will be Dark Elixir and will be produced in dark Spell Factory. Spell Cost: 1000 dark elixir. Producing time:2h and 30 min. Damage per second: 500. Effects will wear out in 4 seconds. I know the troops will be over powered but the game will be better with a dark Spell Factory that will be unlocked at Town Hall 9. (Only five troops will go underground and explode, not all of them) Upgrade the spell to affect more troops. This is my best post and please agree, please!!!
