Illumination. The Yagahn sheds bright light in a 15-foot radius and dim light for an additional 10 feet.

False Appearance. While the Yagahn remains motionless, it is indistinguishable from a normal paper lantern or the container in its original form.

Immutable Form. The Yagahn is immune to any spell or effect that would alter its form.

Bite. Melee Weapon Attack: +1 to hit, reach 5 ft., one target. Hit: 2 (1d4 − 1) piercing damage plus 1d4 fire damage.

The evil eye. The Yagahn can do his fiery tongue evil eye plus a different one in one turn at one or two creatures it can see within 90 feet of it. 

1. Fiery Tongue. It hurl a mote of fire at a creature or object within range. Make a ranged attack against the target. On a hit, the target takes 1d10-1 fire damage, if the damage is 0 it counts as a miss. A flammable object hit by this evil eye ignites.
2. Mache Skin. The target must succeed on a DC 12 Strength saving throw or be restrained for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. The target is hit by paper, pieces of leather or other similar material that begins to stick to his skin and flesh and begin to harden, if he is hit by the evil eye again while under its effects, his skin will be completely covered and petrified by 1 turn, in the next turn a set of mocking drawings of the physical characteristics will appear on the material that covers him and he will start to move under the control of the Yagahn, you can use the stats of the target or those of the zombie, but if you use the zombie remember that only he can use non-magical equipment and, if he has spells, only cantrips. To free the target from the evil eye vast with doing enough damage to knock the zombie down, if that happens the material will shatter revealing the target, stunned.
3. Simplified Vision.(recharge 3) The target must succeed on a DC 13 Wisdom saving throw or be charmed for 1 minute. The target can repeat the saving throw at the end of each of its turns, with disadvantage if something has been damaged visible to the target, the more things have been damaged the more times one has to roll on the save, ending the effect on itself on a success. The vision of the target's reality is simplified (some examples: he sees everything as a board game and most others as, literally, pieces of the game, he thinks he is a child, he thinks he is in a fantasy world where no one suffers and everything is sweet and childish AND HE LOVES IT!)
4. Intoxicating Mirage. The target must make a DC 13 Constitution saving throw, taking 16 (3d10) poison damage on a failed save, or half as much damage on a successful one, on a failed save is blinded for 1 turn. The target begins expelling poisonous black smoke from its eyes, smelling of charcoal and fire.

Arcane Hunger. If the Yagahn makes a successful saving throw against a spell, or a spell attack misses, the Yagahn will swallow the spell, negating its effects, and send a negative wave to the caster who will automatically receive an evil eye, the caste will allway be hit or fail the save.
