Oh I just realized, the Strains have some typos. I didn't have time to do a second pass over them while I was doing the game jam!
For the Stygian Strain, the Binding Touch and Boneless Contortion abilities are meant to be for level 4. Glistening Flesh and Ocean of rubber are meant to be level 5.
There are also a few places where I capitalized things incorrectly. I did the rough draft of the rules in Google Docs before I copied it to Affinity Publisher, and I was using the Lacquer font which has very indistinct capitalization. Google docs will catch incorrect punctuation, but only if the first letter is lower case. If the first letter is upper case... It ignores the capitalization for the rest of the word.
I'll fix that in the next version, and do a second look for all the problem areas.
