Slayer build for Boss Rush Chaos Lvl 5

[LatromTabmok]

Hello everyone,

I thought I'd reach out and hopefully get some input. I'm trying to unlock the achievement for killing a boss on Chaos Level 5 in Boss Rush.

Does anyone have any tips on which boss is "easiest" on this difficulty?
Also, I'm playing a Slayer, so any build advice would be great too!

I appreciate any help, thanks for reading : )

The unclean one is easy but it's C5 so you should be good with any boss.
