Looking for a rule: modifying spell effects

RogerBW · 12-29-2016, 09:56 AM

I have a dim recollection of having seen, somewhere in GURPS 4e, a rule for applying Enhancements to standard GURPS Magic effects. I think that it produced either penalties to cast, or increased energy cost, or both.

Anyone know what I'm talking about?

You're probably looking for Spell Defaults from Thaumatology p. 39. Basically, a mage can apply 5% of enhancements for a skill penalty and increased energy cost.

These rules got expanded in Thaumatology: Magical Styles and used by Antoni Ten Monrós to create his Essential Magic spells in PYR 3.25 - though he gave 10% of enhancements for the same changes, but then these were fixed spells not on-the-fly modifications.

Thanks! I think it was the Magical Styles version I was thinking of.
