Doom priest, scyl of drakes and omg, stag knight. Peydma should be usefull but you already have Tayrell For A1 decrease attack 50%. Don't bother with frozen banshee as you already have occult brawler and the posions would stack over the 10 debuff limit. Yeah she has the poison sensitivity debuff but you might not even get that off when paired with Occult Brawler in clan boss fight and personally i tried them both and he does more dmg on clan boss. Although it depends on the amount of other debuffers you have. Meaning after 10 debuffs your locked out of any other debuffs like decrease attack. Coldheart is a must, try and get one more. For clan boss you may need pain keeper but she is situational. legendary are mostly a given due to their base stats. Hope that helps.
