The Wendigo has advantage on Wisdom (Perception) checks that rely on smell.   Light Sensitivity. When in bright light, the Wendigo has disadvantage on attack rolls and Wisdom (Perception) checks that rely on sight.   Rampage. When the Wendigo reduces a creature to 0 hit points with a melee attack, it can take a bonus action to move up to half it's speed and make a Claw attack.   Regeneration. The Wendigo regains 12 hit points at the start of it's turn. If the Wendigo takes Fire damage, this trait doesn't function at the start of the Wendigo's next turn.
