The dome trap helps prevent lightning from a tower.
You will only get 1 dome trap (TH 8) maybe 2 (TH 9)
Cost: 2,000 dark elixir
You can toggle to turn on or off the dome on any building (but in only 1 building). For example, if I put the dome on a mortar, I cannot put the dome anywhere else because it's already protecting the mortar ( since I have 1 )
Anyways, let's say you have a dome on your dark elixir storage. If an attacker uses lightning on the dark elixir storage, the lightning will not hurt the storage in any way. After 10 shots of lightning, your dome needs to repair (5,000 elixir).
