Best you can hope for is the orb of water, but dispel negates that. And you don't want to use the orb too much or too often.
You can do is regular damage reduction (stone skin doesn't work against invokers, because it just results in a stoneshatter, which is the most abundant for a warrior). Aura and shield are your best bet, but not exactly readily available as a warrior.
At least with lightning, fire and ice, there are resist preps you can burn through. Yes, they will get dispelled also. But at least you have the option to burn through a bunch of your own preps, like they do with a/b/s.
