Battered Retriever

Innate Spellcasting. The battered retriever's innate spellcasting ability is Wisdom (spell save DC 12, +4 to hit with spell attacks). It can innately cast web 3 times per day, requiring no material components. 

Web Sense. While in contact with a web, the battered retriever knows the exact location of any other creature in contact with the same web. 

Web Walker. The battered retriever ignores movement restrictions caused by webbing. 

Multiattack. The retriever makes two foreleg attacks and it uses force or paralyzing beam once, if available.

Foreleg. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 15 (2d8 + 6) slashing damage.

Force Beam. The retriever targets one creature it can see within 60 feet of it. The target must make a DC 14 Dexterity saving throw, taking 16 (3d10) force damage on a failed save, or half as much damage on a successful one.

Paralyzing Beam (Recharge 5-6). The retriever targets one creature it can see within 60 feet of it. The target must succeed on a DC 16 Constitution saving throw or be paralyzed for 1 minute. The paralyzed target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

If the paralyzed creature is Medium or smaller, the retriever can pick it up as part of the retriever’s move and walk or climb with it at full speed.
