True, but in 5e those feats come at the cost of attribute bonuses and that situation only really applies against creatures that you can eat (due to size). In most combats with few enemies, the enemies are either very big or are spellcasters. Due to the nature of the vore system, it excels against single targets while the nature of the D&D system is to make single targets difficult or impossible to get into your mouth.<br/><br/>I have been doing my best to approximate the 5e rules for swallow whole rather than using the older system. In this edition, you don't actually cut your way out of an enemy. Instead, you end up upsetting their stomach and forcing them to release you. This requires doing an amount of damage equal to roughly 1/10th of the creature's health in a single turn to its stomach. The creature is then allowed a Constitution save to keep its prey inside. The DC for this save is based off of the creature's own Constitution modifier (10 + mod) and essentially amounts to a 50/50 because of this.<br/><br/>That said, the above rules only seem to apply to bigger creatures. Some creatures don't give the prey inside them ANY options of escape other than hope their party members kill the creature and to help contribute to its death by attacking from within (giant toads).<br/><br/>As for AC, there are no AC values listed for monsters that swallow players whole. Swallowed creatures are both restrained and blinded, giving them disadvantage on their attack rolls. Nothing in the rules actually limits you to light piercing or slashing weapons for the damage either.<br/><br/>In general, the Swallow Whole mechanic this edition is anything but uniform.<br/><br/>I was considering setting the AC of your stomach equal to your Constitution score. This combined with there only being a chance of you releasing the target and the fact that the prey have disadvantage on attack rolls would better fit the bounded accuracy system and make the AC based entirely upon your natural toughness. Players also receive proficiency bonus to that Constitution save to keep prey as long as they are proficient with Con saves, meaning they could have an easier time of it than monsters.<br/><br/>Anyways, here's what I've got so far. Forgive my lack of forum formatting knowledge if that doesn't actually turn into a link!
