Definitely the Boots of the Vampire. Last time I played they had the following stats:

Boots of the Vampire

Durability 10
Weight 20
[color:"yellow"]Charm Quality: 5[/color]
[color:"blue"]Armour: 270
5 Percent Chance of Absorbing Damage
+4 to Defense
+80 to Vitality[/color]
+10 Resistance to Spirit
[color:"blue"]Recuperation Time 5[/color]
Required Strength: 10

The armour rating is very high, the vitality bonus is considerable, the spirit resistance is great and you can add five charms!
(The stats are random, so try a couple of times.)

So go get those boots! <img src="/ubbthreads/images/graemlins/kitty.gif" alt="" />

I am in blood
Stepp'd in so far, that, should I wade no more,
Returning were as tedious as go o'er.
