Osmosis Shield only drains Vim when it's regenerating HP

[Rutee]

I know it's traditional to treat everyone as hypercompetent, but I can't count the number of times I've died because I move into a fight with it down. It's instant, even, so I don't think it would be breaking anything for this to be the case. That way you only lose it when you run out of Vim (or turn it off to prevent yourself from running out of Vim). I don't think anything about it's functionality would be stronger for it either.

I think this is an excellent adjustment. It mitigates excessive micromanagement.

I tend to run with it on Auto on sight of enemy. That helps a lot.
