In order to successfully capture the flavor of the Moorcock novels I had to create some new skills and modify the Magic system. Each skill is listed with a genre based upon the story scenario it should be played with.
SPELL CASTING!!!! Mana levels fluctuate between NONE and HIGH depending on where you are in the Young Kingdoms. As a rule of thumb, the more Chaos oriented a region...the higher the Mana (and vice versa!). All spells are cast using the RITUAL and RUNE magic rules (as per GURPS Magic). All Casting Times are at least 1 second more than listed and the GM determines which Rune Lores the Sorceror/Priest must know before he can learn the desired spell...it is not easy to begin with, but as you progress, it is all worth it.
