Re: OOC Yes
If you learned of the ritual as part of a prepared spellbook, prepared formula book, prepared meditation book, or prepared prair book, then you have to have at least three spells, or formulas from the book.
You can't get around this, can't UMD, can't sing, or dance, or mechaSheva around it.
This is if the ritual is gained from a prepared source. It is possible however to learn rituals from other sources, but in all cases rituals have certain conditions associated with them, and those conditions have to be met. As I've said before, Mako, if you aren't a spellcaster, then either hire one, or obtain one through the downtime system, or discuss a plan with the Meta to ttry and gain the ritual through another means other than via a prepared spellbook. I forget what ritual you want, so can't recall if there is already other ritual forms for the one in question, and yes some rituals don't require you to be a spell caster, or require a UMD check (no ritual allows for a UMD check that I'm aware to get around its requirements), but if you tell me the ritual, I'll check into if there is another existing means for getting the ritual already listed in source material. Keep in mind all the rituals if not from a prepared book aren't easy to perform, usually requiring more than one person, and multiple checks. If you want I can link you to a few rituals to demonstrate what I mean.
I'll try and check back in tomorrow, but as a crisis shelter volunteer, and given current matters, as you can understand I'm a bit on the busy side.
