A gray man, composed of what you believe to be paper, appears in front of you seemingly from nowhere. He turns to his left, vanishing again into thin air. The next time you see him, he’s right in front of you, bladed arms crossed, ready to slash you.
Str 15, Dex 23, Con 14, Int 13, Wis 12, Cha 12
A thin man only exists in two dimensions, allowing him to deliver vicious attacks with his arm blades, as well as providing a measure of defense against those who have trouble perceiving him. A creature must make a DC 22 Perception check when attacking a thin man. Success means the thin man only has concealment against the attack, while failure means the creature has total concealment. The DC for the Perception check is Dexterity-based.
