These skills seem okay when you first get them, but as levels increase and damage and armor increase, it's clear that they do not scale properly at all.
At level 17, it's 158 armor for those around the caster. That's enough to be easily broken in one single attack from one single enemy. It needs to restore at least double that by that point. I've now unmemorized them, they're just worthless.
The short range doesn't help either.
