Hello, fellow rejects! I humbly come with a question!

So, I'm an Ogyrn guy. Absolutely love being the big meat shield with a big metal shield. Just recently, I decided that I wanted to enjoy the Zealots Thunder Hammer and all its shocking glory. Im lvl.... I think 15 now, and I'm curious about a party sustain build. I want to keep my team up at all costs, but I have no idea what I'm looking for in terms of build, weapons and curios. Any info is appreciated, and may the Emperor protect!
