A Manyfang Weapon of Unerring Direction (MIC) and Ruin (ELH) would be made of WIN and AWESOME.
Add Kaorti Resin for fun.
Use a Kukri or 2 + Blood in the Water.
You can Crit objects and constructs as if they were living creatures, a crit from you does x7 damage from normal, you ignore miss chances, DR and Hardness...
Getting into a vault was never easier.
Plus, since you can Crit Objects, you can charge Blood in the Water to Infinity by dragging it on the ground - expect Druids to attack you on sight for bringing Ruin to the world (you leave a crater behind you, just walking...).
Add Bodyfeeder (+3), and you have a TON of THP, all the time, by attacking the ground - you treat it as a Living Creature, so Bodyfeeder works.
