In Pathfinder Society, what happens to the spells stored in a Vibrant Purple Prism between sessions. I assume they would stay, but that could lead to shenanigans.
I have a character that has no caster levels. I was pondering buying a few Cracked Vibrant Purple Prisms and a hand full of pearls of power. When one of my buddies has a first level spell I like, I could have him cast the spell into one of the ioun stones and then recharge the spell with a pearl of power. If it's a spell I find especially handy, I could have the magic slinging party member cast it into 2 or 3 ioun stones and save them for future adventures. I was also pondering getting a metamagic rod of extend. Having a couple extended castings of Shield or Enlarge Person could come in handy.
Is this allowed?
I think there is a limit to what spells carry over between games.
However, for the purposes of making them easier to track, buy wands for 2PP of the basics (Shield, Longstrider, Lead Blades).
Then invest in one point of UMD so that you can at least roll until you get it or it comes up a 1 (which still lets other people try to work it for you).
I only mark them off once I actually burn the charge from the stone, instead of when I originally activate the wand (provided it isn't the last charge).
Wands are fine, but with the short duration of spells like Shield, if you are playing honest you can burn an awful lot of charges on a single dungeon. If you can get a 7th level buddy to cast a few extended shields into Vibrant Purple Prisms you can save a lot of wand charges. Also, some spells just aren't very useful cast from a wand, but could be very useful if you could get a higher level caster to cast them for you. Like vanish or Blade Tutor's Spirit.
Usually when I post a question like this over there, it gets kicked over to the rules forum.
It'll really depend on the question. If it's clearly worded like yours was and references PFS things, like in between PFS sessions, it normally stays in the PFS section. It really depends if the question is 'how does this work in PFS' vs 'how does this work in general'.
Well, I posted in the Society section and had an answer with a link to the errata in 6 minutes. Thanks Graystone.
Glad it worked for you. Happy gaming! :)
