From publisher blurb:
Magic in Savage Worlds depends on Power Points. The core book provides the alternative No Power Points Setting Rule, yet that still relies on the underlying structure of Power Point cost and makes upper Rank powers highly unreliable in use.
Furious Magic is built from the ground up to provide magic use with no reliance on or reference to Power Point cost. Basic spellcasting stays fast and reliable, while Power Modifiers bring difficulty and the potential of consequences for using more powerful magic. In Furious Magic, spellcasters can choose between easy casting of basic spells or risking higher chances of failure and Backlash for additional effects. In the same spirit, duration of powers works differently and becomes a conscious choice between short use of duration powers or the benefit of long-running powers at a price. This leads to an overall increase in power (pun intended) of arcane heroes and we highly recommend setting-specific limitations like restricted power and Power Modifier lists for each Arcane Background.
