A life hack for hermetic Magi with a few good virtues (source on Ars forums). In short – the idea is that a memory palace has a certain number of “rooms” which can contain a single document, and as a casting tablet is a single document – it can be memorised.
While I’ve no strong feelings on casting tablets, ever since I came up with the idea I’ve wanted to play a character with a personal vis source in mentem and the memory palace skill. the character would frequently use the Creo Mentem “add a room to your memory palace ritual” (I forgot the name) to memorize casting tablets thereby effectively learning (but not really learning) a whole mess of spells. – Erik Tyrrell
I love this. Its broken, but its great.
