Let's say in a magical world, there exists a basic cooling spell which slightly cools down an area by reducing the heat energy of everything inside it.
In said world there also exists a particularly creative and capable mage that has managed to take this spell and massively compress it, reducing the effective area to a small cylinder but massively amplifying the effect in the process.
A few high-level enchantments later and now this spell is attached to a handle, creating some sort of incorporeal lightsaber which cools down anything it phases through. The incorporeal part means that the conventional protection against cold won't work, this weapon is capable of directly affecting someone's internal organs. The compressed spell can't be activated for too long at a time, so it can only last for very few seconds per activation.
Question is, just how effective of a weapon would this be? What would happen when this blade passes through a human being, rapidly cooling down a section of their body in their process?
- I have a magical lightsaber-like weapon
- When activated, creates an incorporeal cylinder blade ~5cm in diameter and lightsaber-like in length.
- Activation is limited to about 3 seconds at a time, followed by a significant recharge period of 10-15 seconds.
- Anything touched by the blade's area is rapidly cooled down, say a 15C temperature drop.
- How effective is this weapon against fleshy beings like humans?
I'm trying to balance this so that it is an effective side-weapon when used right, but not so devastating that it's basically an instant win button.
Edit log: Freezing rate changed from 40-50 C/s -> 15 C. It no longer freezes over time but a flat temperature reduction, to promote swinging instead of just sticking it at the same place for the whole duration.
