@mikemearls @JeremyECrawford @ChrisPerkinsDnD Why don't the Cadaver Collector, Eladrin, Skull Lord, Sorrowsworn, Steel Predator, Super-Trolls, and many others have save proficiencies? All of the above are Cr 10+, so they should have them.

No rule requires monsters to have saving throw proficiencies. See "Saving Throws" in the "Monster Manual" (p. 8) for more information. #DnD https://t.co/5dPKeiq5YJ
