Hypno-spell

This spell is a dark spell that takes up 1 space. When placed on enemy clan castle troops or skeletons from the skeleton trap, it will hypnotize them to fight for you for a short time. The spell takes up 4 tiles and only lasts for 2 seconds, then disappears. At level one it costs 120 dark elixir, and the troops are hypnotized for 7 seconds. Every upgrade makes the troops be hypnotized 1 second longer. At level 2 it costs 150 dark elixir, at level 3 it costs 200, at level 4 it costs 270, and level 5 it costs 400. Upgrading to level 2 costs 7,000 dark elixir, upgrading to level 3 costs 15,000, upgrading to level 4 costs 25,000, and upgrading to level 5 costs 40,000. Please consider using my idea. You can make as many tweaks to it as you want.
