A few spell ideas:

[InfernoLord]

Hypnosis Spell:

A single target spell that can be used on the enemy's defences or clan castle troops. The spell temporary makes the target help you defeat the enemy's base. For example: if you cause the spell on an archer tower, the archer tower starts shooting at other defences or clan castle troops in range.

Revealing Spell:

A small ranged spell that reveals all traps in range (it can also maybe disarm them).

Target Spell:

Sometimes I want my troops to attack a building, but they have their favorite target, or other problems. This spell is made to set a goal for all the deployed troops at the moment. You deploy the spell on a building, and the deployed troops' target changed.
*After destroying the selected target the troops will attack their favorite target again.
