Corrupted Construct

Eye of Insanity. Any creature that starts its turn within a 25 foot cone in the direction the pupil is facing must make a choice to either make a DC 14 intelligence save or avert its eyes giving it disadvantage on attack rolls and losing line of sight for the purpose of spells. If the save is failed the creature takes 2d6 psychic damage and half as much on a successful save.

Deafening Tone. As an action the Module can increase the volume of the warbling around it to incredibly powerful levels, any creature within 10 feet of the Module must make a DC 16 constitution save or take 6d4 thunder damage or half as much on a successful save.

Enticing Gaze. As an action the Module can focus on one target with 60 feet of it, The target must make a DC 10 charisma save or the module will entice the creature to look deep into its “pupil”, the target will only be able to move and look towards the Module and will take damage from the Eye of Insanity ability regardless of where the creature is. This effect will continue for up to one minute and the saving throw can be repeated at the end of the creature's turn to break free from the effect.

Perfect Mimicry (2/day). As a reaction after being touched in any way or being hit by a melee attack the Construct gains 25 temporary hit points and begins to change its form. At the beginning of the next round of combat it changes its form into that of its attacker. During the next round the Construct replaces its statistics with that of the attacker and gains access to any actions, spells and abilities the attacker has. At the end of that round of combat the Construct collapses back into its original form and loses any remaining temporary hit points.
