Congrats sitnaltax, and that's a very nice approach caviar!
In the mean time I crossed out some VGT badges:

To top the silliness I even got to self cannon in my last sub, was even healing in the process!

All thanks to the lucky find of Plate Mail on my 9 lifesteal/31% resist Vamp.
Btw as I never faced VT Horatio before, my previous Vampire suggestions were bad - RBS is essential, the goat has 120/180 damage. I expected him to get a health boost as opposed to damage, which mixes things up. This makes Platemail better too, but DS is a better prep.
Tinker, have you tried Orc Wizards of Binlor with prepped Rock Heart? In terms of flexibility and melee strength it's very far from pure casters, but when you observe how much damage can you dish out with Pisorfs it's worthy of the caster title too. If you run into B2P as well, you can cast Pisorfs at virtual 1/3 - 0 mana depending on which Binlor boons you spam.
