Skeleton Wolfguard

CREATURE 0

UNCOMMON MEDIUM MINDLESS SKELETON UNDEAD

Without the burden of flesh, skeletal wolves charge across the battlefield with terrifying speed.

Among the ranks of the dead, none are so numerous, nor so varied, as the skeleton. While most are almost entirely made from bone, some maintain a few scraps of flesh to aid them in movement, such as wing membranes.

Skills Acrobatics +6, Athletics +4, Stealth +6

Void Healing

A creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.

Speed 35 feet

Melee Jaws +8 (unarmed), Damage 1d4+2 piercing

Screaming Skull (auditory, emotion, fear, mental)

The skeleton removes its skull and throws it, making a jaws attack with a range of 20 feet. It then attempts to Demoralize each foe within 10 feet of the target.

The head bounces, rolls, or even flies back, returning to the skeleton at the start of its next turn. The skeleton is Blinded until then.

Surge of Speed

The wolf skeleton Strides three times, but it's Off-Guard until the start of its next turn.
