So far in Tier 2, my adventuring usually ends when I run into rocket puppies. Their rockets seek, do ridiculous damage, and are very fast. Shields seem to be pretty much useless. If there's only one of them firing rockets, I can usually make it through, but of course there is never only just one.
Suggestions?
I use an owlite shield and rocket impact does next to nothing on that. Perhaps it's the elemental damage, I don't know. It seemed to me like if you don't let the rocket explode but absorb it on your shield instead, it can't hurt so much.
You can make the rockets hit something else. It takes a little maneuvering but you can make the rocket pups kill eachother. Have some fun while you're at it. :)
