Keen Hearing and Smell. The aardvark has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Evil Death Stare. If a creature starts its turn within 60 feet of Aaaalan and the two of them can see each other, Aaaalan can force the creature to make a DC 15 Constitution saving throw if Aaaalan isn't incapacitated. On a failed save the creature takes 21 (6d6) necrotic damage and is frightened of Aaaalan for one minute. While frightened in this way the creature is also paralysed. The creature can repeat the save at the start of each of its turns. On a successful save the effect ends.

A creature that isn't surprised can avert its eyes to avoid the saving throw at the start of its turn. If it does so, it can't see Aaaalan until the start of its next turn, when it can avert its eyes again.

If it looks at the Aaaalan in the meantime, it must immediately make the save.
