Most of the air attacks would fail under the effects of this spell.
@Radioactive Spell: Again, the duration was not the main problem. Just like mentioned before, there are a lot of attack strategies who struggle to defeat a base, which would struggle a lot more under the effects of this spell.
@Invisibility Spell: This spell is listed in the stickies, not as ruled out but as a possible addition in a future update. It does not mean it will necessary be added, but SuperCell considered at a time they might think about it.
