I was wondering how you'd do
Dying Earth-style Vancian magic in TFT. In
Dying Earth spells had to be memorised, squatted in the memoriser's mind causing mental stress, could be used once and were then forgotten.
I think a natural way to do it would be:
- Characters learn spells as usual.
- Learning a spell allows you to memorise it by reading from a book.
- Memorising a spell reduces the wizard's adjusted IQ by 1.
- All the IQ tasks like perception and willpower checks use adjIQ.
- Casting a spell costs no ST.
- When you cast the spell you forget it.
- When you cast the spell you get the adjIQ back.
A few ambiguities and unanswered questions:
- Do you need adjIQ equal to a spell's IQ requirement to memorise a spell? I think probably yes.
- Do you need adjIQ equal to a spell's IQ requirement to cast a spell? I think probably yes.
- Can you forget a spell and recover the adjIQ without casting it? I think probably yes.
- Can you memorise several copies of a spell? You never see anyone doing this in Dying Earth, but it's not clearly ruled out either.
- How do you pay the per-turn cost of a spell?
- How long does it take to memorise a spell?
Some interesting consequences:
- Wizards would have to start with weaker spells and finish with strong ones as their adjIQ recovered.
- Wizards wouldn't be as useful as scouts, since a lot of the time they walk around with low adjIQ.
- Wizards wouldn't increase their fragility as they cast.
- Wizards might use a wider variety of spells.
- Wizards will need to bring their spell books with them.
