Arcane Puppet

Will of the Puppet Master. The modifiers for ability checks (saving throws and skill checks) in which the puppet is proficient increase by 1 whenever your proficiency bonus increases by 1. The puppet also gains bonuses to its attack and damage rolls equal to your proficiency bonus.

False Object. If the puppet is motionless at the start of combat and a hostile creature hasn't observed it move or act, the puppet has advantage on attacks made against that creature during the first round of combat. Moreover, that creature must succeed on a DC 15 Wisdom (Perception) check to discern that the puppet is animate.

Evasion. When the puppet is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.

Head on a Swivel. The puppet cannot be surprised.

Blade Fury. Melee Weapon Attack: +2 + PB to hit, reach 5 ft., one target you can see. Hit: 7 + PB (1d8 + 2 + PB) magical slashing damage. 

Arcane Bolt. Ranged Spell Attack: +2 + PB to hit, range 120 ft., one target you can see. Hit: 6 + PB (1d6 + 2 + PB) force damage.

Scurry. When a creature misses an attack against the puppet, it can move half its movement speed in any direction without provoking attacks of opportunity.
