Hey, thanks! Glad you like it!
Your suggestion is indeed pretty cool, I might genuinely add it (I'll credit you if that's the case), I just need to think wether it fits as a base rule or as an additional one as suggestion for effect for equip, abilities, ecc, to keep the overall atmosphere of this system.
for the license, I indicated in the info in this page creative Commons 1.0, the free for all one uhuh.
I searched this mosaic strict you suggested and it's indeed a really interesting way of categorizing this things, but what would it mean to publish it as a piece of it? Just adding it in the description to let people know what it is?
