Source magic has two primary uses.
- Providing power to other streams
- Investigating magic
A Source mage can tell at a glance what sort of power another mage has and whether they have any active effects running. With a little concentration, the Source mage can tell what those effects are doing.
Those with real skill can shut down another mage’s effects entirely, or even cut someone off from their power.
Source mages are more likely to be male.
