deffense and loot spells

Make 2 spells via dark elixir or regular elixir and take for example: if it is a defensive spell then the troops in that circle will go only for the defenses or if it is a loot spell then they go for loot and say you put down the loot spell they will ignore the defenses and buildings and just go for collectors mines and storage's.(sorry for the punctuation and grammar mistakes) id say make then both approx 1k each on dark elixir cause it would be a good spell or a nice spell to have around but also make it so they still got to go through walls. it lasts like 15 seconds or so for both of them.
