Really cool rituals. They really are powerful, so be careful and dont hand them out to your PCs, make them pay something for adquiring them.

Rituals are one of my favorite parts of UA, because, as Maichen puts it, "rituals aren’t just ‘spells’ in the traditional D&D sense, but story seeds." Every time I have (or am) a ritualist PC I dig through whatever published or third-party stuff I can find, excited to see what I can dangle in front of them to make them go "gimme!" (or "what." or "yeah, NOPE!"), and from the NPC side I love thinking about/designing/using rituals that make the world feel exciting and strange.

There's a page of talk about the how and why of ritual design from the GM perspective, with an emphasis on that "story seed" idea over "balance." It was well written and on the nose. The other 11 pages of content are dense with rituals. Not all are written exactly the way I would (1), but all of them fit at least one of the hoped-for roles I listed above, and that first page gives you both basis and permission to tinker. I particularly liked the story potential of Mariaj Lwa (wed someone to the nearest incorporeal entity!) and The Doe/Demon Mother pair (make a woman incredibly fertile for life... or put a demon in the drivers seat of her baby). I might not use all of them, but none of them bored me.

If you plan on running UA or are thinking of playing a ritualist PC, this is absolutely worth your buck fifty (and if you're not thinking of playing a ritualist PC, you might after you read this).

(1) Namely, the rituals for teleporting packages, one-way teleportation of the caster to a prearranged place, and making binding contracts. I loved all of them as concepts, but feel I like my usually over-clever player base (...or me as a PC, let's be honest) would leverage them too well. If I threw them in I'd make them some combination of difficult as hell to get, involve more of a PITA ritual, have bigger downsides and/or risks, be significant instead of minor, or some combination thereof.
