Annointment: SNTL cryo, consecutive hits Shield: Whatever you want, the One Shotter or any amo shieds are good for bossing, you can also use the Front loader for a URad setup Weapons: Mobbing: Light show, do some testing to see what you like Bossing: Backburner, make sure to match elements. Artefact: snowdrift victory rush: If you shoot the backburner while you slide, you will deal insane damage. Classmod: seeing dead, points anywhere ara fine, no need to have +5 into Donnybrook, you are only interested by the bonuses it gives you.
Skill Tree: Violent Violence and Playing Dirty: Cap those at 5 using the points in your classmod, no need to go higher. Ex: My Seeing dead classmod gives me +3 into Violent Violence, +1 into Playing Dirty and +1 into Donnybrook, hence my points distribution in those two skills.
