I was able to solo him at 27 using evasion and a health pot.
I snuck in the front entrance and went to the right and dropped down.
You have to kill a slime, then eat. After that, VF wanders by and you can pull him.
I recommend bringing plenty of food/bandages, health pots, flash powder, and poison.
Watch out for the Irradiated Troggs, as they can break your stealth.
Edit: Update:
15 kills, 13 Boots, 1 Hydrocane, 1 daggers.
Frustrating.
