[RPG] What are small or tiny creatures that paralyze

conditionsdnd-5emonsters

In Adventurers League, there is a new option to submit modules for conventions that can become Adventurers League “certified.” One requirement is that only existing creatures can be used.

We have an adventure that calls for a small scorpion sized creature that paralyzes but now need to find a substitute because Monster Manual scorpions have poison without paralyzing effects.

What are viable current Adventurers League legal creatures that are small or tiny (such that a sleep spell could knock out a dozen of them) but that also paralyze?

Addendum:
Per a question below, yes, falling unconscious would actually functionally work as well.

Best Answer

While not paralysis the Sprite can knock people out and only has 1d4 of health.

Their shortbows read:

Hit:1 piercing damage, and the target must succeed on a DC 10 Constitution saving throw or become poisoned for 1 minute. If its saving throw result is 5 or lower, the target falls unconscious for the same duration, or until it takes damage or another creature takes and action to shake it awake.

The Pseudodragon has a similar poison lasting 1 hour but has more health at 2d4+2.
