The way I'm envisioning them is that they function similarly to a <a href="https://roll20.net/compendium/dnd5e/Rug%20of%20Smothering#content" target="_blank">Rug of Smothering</a> except you can't speak while grappled & they don't deal damage. What differentiates them is (a) when you're grappled by a Killer Pillow you lose all held breath, and (b) when a grappled creature starts its turn, it reduces the number of rounds it can survive without air by 1.How do I adjudicate this monster's CR? Specifically, its offensive CR?Rules on suffocating from PHB for reference:[SECTION]SuffocatingA creature can hold its breath for a number of minutes equal to 1 + its Constitution modifier (minimum of 30 seconds).When a creature runs out of breath or is choking, it can survive for a number of rounds equal to its Constitution modifier (minimum of 1 round). At the start of its next turn, it drops to 0 hit points and is dying, and it can’t regain hit points or be stabilized until it can breathe again.For example, a creature with a Constitution of 14 can hold its breath for 3 minutes. If it starts suffocating, it has 2 rounds to reach air before it drops to 0 hit points.[/SECTION]So, conceivably, a Killer Pillow could knock unconscious a PC with Constitution 14 in just 2 rounds if not dealt with or circumvented.It seems to defy the monster maths in the DMG. Would it be better handled as a trap? Or is there some math I'm overlooking?<img src="http://i.imgur.com/q3l78xn.png" alt="" class="fr-fic fr-dii fr-draggable " data-size="" style="" /></blockquote>
