Mordenkainen’s Faithful Hound 5e

Mordenkainen’s Faithful Hound 5e

Level: 4th

Classes: Wizard

Casting Time: 1 Action

Range: 30 feet

Components: V, S, M

Duration: 8 hours

All creatures except you view the guard dog as invisible and cannot damage it. When a small or larger creature comes within 30 feet of the guard dog, the guard dog begins barking loudly if the creature cannot speak the command you set during the spell. The guardian dog can see invisible creatures as well as observe the Etheric plane and ignore illusions.

At the beginning of each of your turns, the guard dog attempts to engage a creature within 5 feet of it that is hostile to you. Its attack adds a value equal to the key attribute adjustment of your spell + your proficiency additions. If it hits, it deals 4d8 points of piercing damage.
