鲜红的血液覆盖在武器的刀刃、锤面或尖端上，黏稠浓密的鲜血滴溅洒落在地面上。
此法术会使碰触到的武器覆上一层伤害性的能量，腥血之刃的能量会在这把武器击中活体生物时散发，此法术会使被攻击的生物额外受到1d6点伤害。你可以自愿承受5点伤害让武器再增加2d6点伤害（合计3d6点额外伤害）。
若持有者丢落武器或是以其它方式失去与武器的连系，那武器上的法术也会失去效果。

Red blood erupts along the weapon’s blade,
bludgeon, or point. The blood drips to spatter
in thick, viscous drops upon the ground.
This spell infuses the weapon touched
with baleful energy. The next time this
weapon strikes a living creature, blade
of blood discharges. The spell deals an
extra 1d6 points of damage against the
target of the attack. You can voluntarily
take 5 hit points of damage to empower
the weapon to deal an extra 2d6 points
of damage (for a total of 3d6 points of
extra damage).
The weapon loses this property if
its wielder drops it or otherwise loses
contact with it.
