Compounded Sickness. The Madtrick's cocktail of diseases are potent to even the most resolute fighters. Creatures that are normally immune to disease or poison are instead only resistant to a Madtrick's spore ray.

Aura of Decay. The Madtrick emits a 90ft radius of noxious vapor centered on itself. At the start of each of the Madtrick's turns, creatures caught in the aura automatically take 14 (4d6) acid damage.

Ensnare. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 14 (4d6) bludgeoning damage, and the Madtrip attaches to the target. If the target is medium or smaller the Madtrip will gain advantage on the attack roll. If the attack is successful, it engulfs the target's head causing the target to be grappled, blinded and suffocated while engulfed.

While attached to the target, the Madtrip can Ensnare no other creature except the target but has advantage on its attack rolls. The Madtrip's moves with the target and at half speed while attached this way. The Madtrip can carry and fly with a target up to 500 lbs.

A creature can detach the Madtrip by making a successful DC 17 Strength check as an action. On its turn, the Madtrip can detach itself from the target by using 5 feet of movement.

8. Hallucination Ray. The targeted creature must make a DC 17 Charisma saving throw. On a failed save, the target loses the ability to distinguish friend from foe, regarding all creatures it can see as enemies until the spell ends. Each time the target takes damage, it can repeat the saving throw, ending the effect on itself on a success.

Whenever the affected creature chooses another creature as a target, it must choose the target at random from among the creatures it can see within range of the attack, spell, or other ability it’s using. If an enemy provokes an opportunity attack from the affected creature, the creature must make that attack if it is able to.
