Perhaps one could write up a quick potion that strengthened the imbiber's digestive track, letting it count as a magical natural weapon, as making it a waistband or something that would require attunement would be a hefty price to pay for a magic damage tummy.<br/><br/>And I had totally forgotten that the compression ability was noted down in the Pathfinder VSRD, which do seem to limit their slimey-power to a nice extent, which probably would mean that I could have been less mean to the slimepeople with my proposed downsides to them. Instead of doing the reduced chance to hit with manufactured weapons, which I guess would be a bit of a class-limiting bummer, one could have it so that a humanoid character that would first need to grapple the enemy, could skip the grapple, and instead go right to the ingest step when the prey is a slime, essentially just drinking it up? And of course, if they didn't wear armor, slimepeople should be able to engulf other creatures, essentially ingesting them without needing a grapple first, but instead of trying to escape, their prey could do an opposed strength check, and instead attempt to drink up the slimeperson from within, reversing the swallowed condition with two successful maneuvers.
