Warhammer Shank

Flight. The Shank flies 5ft above the ground using its boosters. If its boosters fail, it collapses to the ground, unable to move, but still able to aim its weapon in front of itself. 

Languages. The Shank knows any languages its current and previous masters know. 

Mounted Weaponry. The Shank's master can mount any weapon of their choice to the Shank, and it will add +1 to its attack roll and damage roll while mounted, plus the modifier the Shank intrinsically has with its strength or dexterity score depending on the weapon. 

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

Shank Slam. Melee Weapon Attack: +3 to hit, reach 5ft., 1 target. Hit: (1d8 + 2) bludgeoning damage. 

Booster Evade. As a Bonus Action, the Shank can ready an dodge, flying in a direction up to 10ft. in a circular radius of itself. Any target who attacks it attacks with disadvantage.

Target Analysis. As a Bonus Action, the Shank can analyze a creature, learning one Resistance, Immunity, Vulnerability, or Sense the creature possesses. It may communicate this to all creatures in a 20ft. radius of itself once, being more easily heard by its current master once it takes this action.
