In what way can a single caster reasonably cast the Youth spell (GURPS Magic, p. 94)?
The Youth spell costs 100 which makes a huge problem to cast it.
The possible ways I found are
- Write a scroll - 100 days
- Slow and sure enchantment - if GM allows it - 100 days
- Ritual casting - which will require a lot of people or 10 very skilled mages
- Having energy reserve or fatigue 100 - which would cost 300 character points
- Having a power or mana stone with 100 points
All those ways needs a lot of resources: time, contacts, money, character points.
Did I miss something? Is there a reasonable way to cast a spell which cost 100 other than that?
