Splatterhouse (3.5e Maneuver)

''BLOOD OF THE BLOOD GOD!!! AHAHAHAHAHAHAHAHAHAHAHA!!!''

You can activate this maneuver whenever you kill a blood bearing creature with a melee attack with a piercing or slashing weapon. You kill them with such brutality and blood spray that all enemy creatures in a 60 foot radius burst must make a Will save or become frightened for 1 round, and shaken for 1 minute afterward, save negates. Creatures in your threatened area save against panic for 1 round, frightened for 1 round, and shaken for 1 minute afterward. Creatures with 4 or more HD than the slain creature are only shaken, never frightened or panicked. Regardless how many are terrified or not, you gain a +4 morale bonus on attack and damage for 1 round (affecting even undead initiators, this is an exception to the usual rule about morale bonuses).

Creatures must be able to see or hear the carnage to be affected by this maneuver. This is a mind-affecting fear effect.
