Possessions are tradeable, and spells are possessions.. This always seamed wierd to me..
Spells are stored in your memory, since the game makes you lose spells from memory losses, damage to the head etcetra.. And when casting spells, the game quite often straight out says that you try to remember the words of the spell..
But some how, spells are tradeable?? How does that happen? Do the investigators transfer them via some bluetooth in their heads, or something??

I used to wonder about this too. My explanation is that they are carrying a tome with the spell text in it, or some small trinket that allows the person carrying it to cast the spell (or even just a piece of paper ripped from a tome, or copied from one). But in order to use either you need a clear head and be able to recite the spell properly (so even if you read it but say it wrong, it could blow up in your face).

Then again spells don't count as items when you are limited in how many items you can carry, which is why I lean more towards the "magical trinket" or "piece of paper with spell written on it", which are small enough to be worn or tucked in a pocket, so having a busted arm wouldn't prevent you from carrying it.

Well.. that would not explain the whole "getting hit in your head so hard that you forgett the magic words and must discard a spell"-events..

Items = Common and Unique Items

Possessions = Items + Spells

Normally when you find a spell, the app describes you finding a sheet of paper or some other small item - most of these seem small enough to carry in a pocket. Most of the items tend to be larger.

Admittedly, there are times when the description of using spell don't match up with the description of how you found the spell. Sometimes it still makes sense given the strangeness of spells in the mythos, but sometimes it just doesn't. The app doesn't track what spells you have available, and even if it did it wouldn't know which you were using if there were multiple spells in play. And even if you got to choose the spell in the app each time, it would still have to remember what description was related to obtaining the spell.

Not worth all the extra coding that could be better invested into more scenarios. I'd rather have the occasional disjointed description

Yes, we find spells in books and scribbled on papers.. But the events says that you read the words. So I was thinking that the spell get etched into your mind, since the investigator have to take horror with learning the spell. Since when learning the spell they learn a lot of heavy truths about the world..
