Paper talismans

[Plane]

M58 has Enchantment spells Talisman and Amulet...
M220 has Alchemical Charms / Alchemical Talismans
Not sure how close this would be to what WAWS wants.

The Talisman spell does 1-time boons which operate like a bonus to roll.

M57 has "scroll" which lets spells be cast from them if you can read... it might be interesting if you had some way to activate customized scrolls without reading them, like via burning paper instead.

"Temporary Enchantment" would cover when you can't read the spell and don't want it indefinitely reusable: 15% the cost if it's 1-use. Not usually as cheap as a scroll, but then you don't need to read to use it.
