Blood Shield (Osebo

). both defense and offense in one. also prevents one damage each *round*.
Unique equipment.

The minion with this equipment may prevent 1 damage from an opposing minion's strike each round. If used to prevent damage from a hand strike made by a vampire with capcity 6 or less, that vampire burns 2 blood.
Aabt Kindred, Ganhuru, Lodin, Alan-Jalav, Dimitri Borodin, ... all have some sort of prevention built-in. pretty sweet out of the box.
@ Kraus: well-marked rocks indeed imho (as long as you also have an Ivory Bow or noone does
'Ablative skin' is another possibility btw.
Of all these, i must say i much prefer 'Leather jacket' over anything else (except at times some of the built-in specials) because of the inherent untap. it also doesn't have the 'non-aggravated damage only' clause that Well-marked (Laibon only) has.
