For a bit of context, my account is level 61, I three key Brutal CB, and my current team is UDK, Apoth, Occult Brawler, Warmaiden, Athel. I'm working on upgrading and trying to get to Nightmare.

Occult Brawler does a lot of poison damage. I recently got Aox and Myciliac Priest Orn. Considering only Clan Boss use, would it be worth it to level one of them to replace Athel or someone else? Do I run into issues with the poison debuffs? OB has a high application rate compared to Aox and Orn, but each of those brings other utility.

I also have Elenaril sitting around if that matters. She is who I replaced when I got Occult Brawler.
