[Meta thread] Lord Windos' PokeRole Adventure : Celadon City Vandels

[Dragonstrike]

Reiner would logically know what they are and what they are used for, as being a fairly high ranked and competent/intelligent Grunt in Team Rocket would have given him at least cursory knowledge of these Items. He might have even been tasked with stealing them from some trainers at some point, and was able to learn more about them that way and/or when Weavile accidently blundered in his Pickpocket check and they got a first hand demostrations....

That, and with Petrel, the Executive known for being in 'The Know' about almost EVERYTHING, due being an accomplished inflitrator/information gatherer, as his best friend, he could have solicited more information about Z-Crystals at anytime. Whether or not because they got curious enough to ask what the heck were so special about them, or wanting to further educate himself after Weavile got Z-Moved into oblivion. Come up with a decent enough backstory reason as to HOW he first learned more about them, and I'll say you know at the Poison, Dark, Ice, and Dragon Dances (As those are the three Pokémon types you originally started out with). Mew can teach you the rest/teach you them period, but given that they are not going to be in the best state of mind when they realize they've under gone a Transformative Thursday, that would have to be at a later date.

Oh, and yes, Key Stone act as catalysts for Z-Crystals as well, mate! Much simplier to do it this way, rather that require everyone to lug around/find a Z Bracelt to use them as well!

Well, Z-crystals are weird in and of themselves in that they're their own catalysts in the games.  You only need to get one, and they somehow replicate themselves in Sun and Moon when you give them to a pokemon to hold, while the trainer holds the original one in the bracelet.  Kinda weird, tbh.

Petrel educating Reiner on them after a blundered pickpocketing sounds like a pretty good reasoning for how he learned about them in the first place.  And Reiner might have also asked Petrel for some demonstrations on them afterwards...partially for his own curiosity, partially so he knew what to watch for in the future.  Though when he realized they all started the exact same way (crossed arms in front of the trainer.  Real easy to spot if you're paying attention, particularly since the dances that follow are lengthy), he really only paid special attention to the five types that his 3 pokemon (at the time) have, in case he ever got the chance to use those in the future.  (That sufficient enough for him to know the Dragon, Water, Ice, Dark, and Poison dances?)

Speaking of Z-moves, how do they work in this campaign since we don't have any mechanics for them in Skull Ruins?
