You can probably convince a DM to provide you with the cantrip scrolls if you are a wizard.
I suppose a certain DM Nocturne would be a DM who can be convinced..... lol
I think convincing a DM to do that is the best way to get one along with finding one IG.
Giving scroll out because it's Halloween or because there is a NCE isn't a good reason. This is a RP place... giving out stuff to every single player for a special occasion feel like we are in some big business MMORPG who give out special item to promoted their game.
If a DM to chose to give out a scroll to someone, well it's a DM, he/she must have a reason to do it.
This server isn't made for lazy people, RP'ing isn't made for easy people, I say go out there and find yourself a scroll. You might buy it from a merchant find it on an expedition, get someone to give it to you.
I highly prefer getting my stuff in legit RP way IG rather then having something because it's a special OOC occasion and everyone gets one.
Edit because someone posted while I was writing :
Well if they aren't in the loot table yet, I suppose you can always convince a DM to give you one or maybe you'll get one of the new scroll through DM event and stuff like that, but even though we can't loot them yet, I personally prefer if we get scroll in a legit way IG
