New spell: Immune

The spell is called immune
It cost 1500 elixir
The spell is cast on your troops within the circle to give them immunity to physical and magic damage for 3.0 seconds

Please let me know if you like this spell at all in the comments. If you think it needs more information about the spell. Awesome spell I think it could turn the tide of the battle.

Wow I haven't heard anything more op than this. For this to be possible it would have to be the size or smaller than a jump spell.

this is a great idea and all, but its too OP. Maybe it should just make troops immune to x bows and infernos and should cost alot
