Wear Yang's, cube Dawn. Yang's has an additional 50% Hatred cost reduction secondary that isn't included in its legendary ability in the cube. Also it has a better damage range than a hand crossbow and naturally rolls % Damage.
With the right weapon equipped you should be free to use Wolf Companion instead of Bat Companion for extra damage.
Yang's is usually a Fire build with Multishot:Arsenal and Ballistics passive.
Thrill of the Hunt and Cull the Weak combined already activate Bane of the Trapped, so there's no need for Polar Station or custom Engineering passive. If you really want sentries, use the Marauder set.
Run Preparation:Invigoration instead. Huge damage boost due to how UE uses Discipline.
Convention of Elements is usually the go-to for the Ring cube slot. You want as much distance between you and your enemies as possible (UE set bonus and Zei's). However, you're only gunning for GR 55 so you may not need the help.
