Puppet

Versatile. The Puppet can be given any singular trait of choice on creation. Once chosen, you cannot change it's trait:

1. Immutable Form. The Puppet is immune to any effect that would alter its form.
2. Faultless Tracker. The Puppet is given a quarry by its master. The quarry can be a specific creature or object the master is personally acquainted with, or it can be a general type of creature or object the master has seen before. The Puppet knows the direction and distance to its quarry as long as the two of them are on the same plane of existence. The Puppet can have only one such quarry at a time. The Puppet also always knows the location of its master.
3. Antimagic Susceptibility. The Puppet is incapacitated while in the area of an antimagic field. If targeted by dispel magic, the armor must succeed on a Constitution saving throw against the caster’s spell save DC or fall unconscious for 1 minute.
   
4. Acid Absorption. Whenever the Puppet is subjected to acid damage, it takes no damage and instead regains a number of hit points equal to the acid damage dealt. (NOTE: You can replace the damage that causes this effect with another damage type.)
   
5. Berserk. Whenever the Puppet starts its turn with 60 hit points or fewer, roll a d6. On a 6, the Puppet goes berserk. On each of its turns while berserk, the Puppet attacks the nearest creature it can see. If no creature is near enough to move to and attack, the Puppet attacks an object, with preference for an object smaller than itself. Once the Puppet goes berserk, it continues to do so until it is destroyed or regains all its hit points.
   
6. Axiomatic Mind. The Puppet can’t be compelled to act in a manner contrary to its nature or its instructions.
   
7. Selective Thoughts. The Puppet is immune to psychic damage, and is immune to the Charmed and Frightened conditions. Additionally, if an effect requires a minimum Intelligence score to work against a creature, even if the Puppet’s Intelligence meets the threshold, they are unaffected as if it did not meet the threshold.

Club. Melee Weapon Attack: +4 to hit, reach 5 ft., 1 target. Hit: 7 (2d4 + 2) bludgeoning damage.

Opportunity Attack. The Puppet can Club any creature that moves out of it's range.
