Hound of Ill Omen

The hound has advantage on Wisdom (Perception) checks that rely on hearing or smell.

The hound has advantage on an attack roll against a creature if at least one of the wolf's allies is within 5 ft. of the creature and the ally isn't incapacitated.

The Hound of Ill Omen can move through other creatures and objects as if they were difficult terrain. The hound takes 5 force damage if it ends its turn inside an object.

When summoned, the Hound of Ill Omen targets one creature you can see. At the start of its turn, the hound automatically knows its target's location. If the target was hidden, it is no longer hidden from the hound.

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6+3) piercing damage. If the target is a creature, it must succeed on a DC 13 Strength saving throw or be knocked prone.
