Inktober Monstrosities: Y for Yugoloth, Guardian

Guardian Daemons or Yugoloth are extra planar beings summoned to protect (or guard if you will) items or places. They come in three different sizes, tall, venti and grande... eh...that is... least, lesser and greater, sharing many traits, though unlike the greater, which always appears as a large, horned and winged bear, with eagle talons for feet and claws, the two lesser variants are not as defined in shape or size.

A bit of a cheat this one, since these monstrosities were originally called Guardian Daemons when they first appeared in the  Fiend Folio for first edition AD&D and the Monstrous compendium volume two, for second edition. Only when reappearing in the second edition Monstrous Manual., were they defined as yugoloth, but with so few good monsters on y I'll grasp at any straw.

The DC for the save against the breath weapon should of course be 15, NOT 115(!).
