[@Xenonia] Armor. That would lessen the kick. (Not to mention I thought it was towards the chest.) And the Thu'ums, by all actuality, shouldn't need a cooldown except to keep people from just spamming them in the game. Now, since Shivani doesn't like using Thu'ums that much, using 2 in quick succession should be allowed.

Whether or not the Thu'um should have a cooldown is irrelevant. The Thu'um has a cooldown. That is pure fact. Stating otherwise would involve defying the rules of the Skyrim setting, which would require reality warping powers.

Using the "character does not like it" reason as to why said power wouldn't be used is not an appropriate way to handle this, as the power is still present and not limited in any way. It reads as "I don't like it so I'm going to spam it."

Also, being kicked in the crotch is excruciatingly painful unless you are protected by something that will deflect the force of the blow entirely, like metal, or a solid cup like those used in sports. Leather is malleable and flexible, and as such the majority of the blunt force will penetrate it. Shivani is in for some serious pain.
