[RPG] Are there any demons of CR 1/2

dnd-5emonsters

Summon Lesser Demons will summon for the caster a number of demons based on a d6 roll; either 2 CR 1 (or less) demons, four CR 1/2 (or less), or eight CR 1/4 (or less).

CR 1 demons include Quasits and Maw Demons; CR 1/4 gives us the Dretch (and Manes are available at CR 1/8). However, I could not find any CR 1/2 demons that the middle result might summon. Searching D&D Beyond for creatures tagged "demon" didn't turn up any demon of CR 1/2.

Does the published material actually include any such demons that this spell result could summon, or is the unlucky caster stuck with getting a measly four Dretches or Manes?

Best Answer

The Cackler

Apparently there were none until the Guildmaster's Guide to Ravnica showed up.The Cackler is the only one dndbeyond.com that fits the CR 1/2 criteria.

To find this, my filter looked at Fiends->Demon Subtype->CR 1/2-1/2.

This article provides a list of vermin to select 'animal' companion from. Note that it actually does not prohibit a non-vermin druid to select vermin companion. Also please note that vermin companion is actually considered magical beast.
Watchspider is a wonderful magical beast located on page 140 of City of Splendors: Waterdeep, which can serve as animal companion, requiring an effective druid level of 4 or higher. It can also serve as familiar or mount, but that's beside the point.
While we are at it, Tressym (detailed in *Forgotten Realms Campaign Settings) is permitted to be an animal companion at 1st level, as per Sandstorm, p48. Although it is just an animal, it is the only animal I know with Intelligence of 12, easily smarter than its druid master.

Important note: with a liberal interpretation of Wild Cohort feat you can use the above Animal Companion choice expansions with it. With a more liberal interpretation you can also use some of the expansions below (e.g. feats). Strict interpretation limits you to the list in Player's Handbook, though.

Alternate Class Features

Complete Mage gives an Elemental Companion ACF. Not exactly Animal Companion (no crazy abilities boost), though. Probably you're better off with Summon Elemental reserve feat.
Urban Companion ACF gives a familiar which is slightly better than a standard sorcerer familiar and is a magical beast. If it can be used in conjunction with Improved Familiar and other familiar-related goodness, then you are set, I believe. Note that Improved Familiar in DMG allows you to have a homunculus as a familiar, which is a construct. Bonus points if you can convince your DM to allow it to benefit from Improved Homunculus feat.

Feats

Exalted Companion (Book of Exalted Deeds) allows a druid to select from a limited list of magical beasts.
Beast Totem (Eberron Campaign Setting) allows to take Totem Companion - one more list of magical beasts to select from.
Devoted Tracker (Complete Adventurer) allows to select your special mount to be your animal companion, effectively giving you a magical beast companion.
Vermin Companion (Eberron Campaign Setting) allows to select from a limited list of vermin.
Spider Companion (Drow of the Underdark) allows to select from a limited list of spiders. Setting-independent, but steep prerequisites and you already can select vermin companions per aforementioned WotC article.

Prestige Classes

Arcane Hierophant (Races of the Wild)makes his animal companion his familiar, which is treated as magical beast from there on.

Dragon Magazine material

Monstrous Animal Companion (Dragon vol. 326), while requiring yet another feat (also Dragon vol. 326), allows to select your animal companion from yet another list of magical beasts. 8-headed hydra, anyone?
Plant Companion alternate class feature (Dragon vol. 357). Gain a plant companion instead of an animal. I'm afraid I don't know the details of the deal, though.
Spell Sovereign prestige class (Dragon vol. 357). Remember Urban Companion? This allows to have living spell as familiar. The details still escape me, I don't own Dragon Magazines.

Third party

Just stumbled upon this.

Ooze Companion feat (Dungeon Denizens Revisited, for Pathfinder). One of the Pathfinder books allows druid to select his animal companion from a list of oozes. Ew.

There may be more.

[RPG] Are there any official stats for a sheep

Storm King's Thunder uses a modified goat statblock for sheep.

D&D Beyond includes a sheep statblock, for which it cites p. 142 of Storm King's Thunder as the source. Looking at that page of the adventure, Grudd Haug area 9 (Stockyard) says to use a modified version of the goat statblock (basic rules, p. 138; SRD, p. 381) to represent sheep:

Use the goat for the sheep, with the following changes:

It is a Small beast with 3 (1d6) hit points.

Its speed is 30 feet.

It lacks the Charge feature and any effective attacks.

Its challenge rating is 0 (0 XP).

Note that the goat statblock is already CR 0, but is normally worth 10 XP - presumably because it does actually have a ram attack and a Charge trait (ineffective though they may be). The sheep statblock no longer has this attack or trait, and its hit die is also slightly smaller so it has 1 less max HP on average. Per the "Experience Points by Challenge Rating" table, CR 0 creatures can be worth either 0 or 10 XP (it's the only challenge rating for which more than one value is listed in the table).

That said, the Wild Magic Surge table (PHB, p. 104) obviously wasn't written to reference an adventure that wasn't even out yet at the time the Player's Handbook was written (one which was released a few months after you posted your question). As nitsua60's answer says, the book itself acknowledges that it can't include statistics for every animal in the world, and leave it open for the DM to approximate something reasonable based on what's provided. Even without owning Storm King's Thunder, one could reasonably have decided to use the goat statblock (as-is or modified) to represent a sheep if needed - SKT simply explicitly codifies that advice for use in the adventure.
