Azurecrest Platypus

Limited Telepathy. The platypus can magically communicate
simple ideas, emotions, and images telepathically with any
creature within 100 feet of it that can understand a language.

Beak. Melee Weapon Attack: +3 to hit, reach 5 ft., one target.
Hit: 3 (1d4 + 1) Piercing damage.

Staggering Shriek (Recharge 6). Each creature within 10
feet that can hear the platypus must succeed on a DC 11
Constitution saving throw or until the end of its next turn, it
must choose whether it gets an action, a bonus action, or a
move on its turn; it gets only one of the three.

Spellwarp (3/Day). When a creature the platypus can see
within 60 feet casts a spell, the platypus forces the caster
to make a Constitution saving throw with a DC of 10 + the
spell’s level. On a failure, the caster is affected in one of the
following ways, determined by rolling a d4:

1. After the spell is cast, any spells or magical effects on the
   creature ends and the creature can’t cast spell other than
   cantrips until the end of its next turn.
2. After the spell is cast, the creature vanishes to the Ethereal
   Plane as with the Blink spell. It returns from the Ethereal
   Plane at the start of its next turn.
3. After the spell is cast, the creature is teleported in a
   random direction to the furthest away unoccupied space
   within 30 feet of it. To determine the direction, roll a d8
   and assign a direction to each die face.
4. The spell takes effect as if it was cast using a spell slot one
   level higher
