To add to what Freelsy had to say, which is correct, both of the virtues Honor and Sacrifice are without a doubt the most important to a Sampire. Sacrifice allows you to rez fully dressed (except for blessed items) with everything that was on your corpse now being with you wherever it is you decided to rez. Add to that the monster ignore of Honor, which lasts for 5 minutes at knight level, and it can become a very simple recovery after a death, no matter where you are. Say you die on DH island. You go to the opposite side of the island from where DH is, rez yourself, then honor yourself so he won't attack you if he happens to wander down. This gives you 5 minutes to recast your spells, get your buffs back up, and wait for mana and HP's to regen so you can get back in the fight. It's well worth the time it takes to reach, then maintain both virtues.
