Editing Shadowjack's GURPS House Rules (section)

==== Place of Power ====
Place of Power [1/level, max. 5 levels], a new advantage for use with the Ritual Path Magic rules. You control a consecrated ritual space that has a history or location that grants +level to all energy-gathering rolls. You are entirely familiar with the location and have placed wards upon it at your highest possible skill level against any category of threat that you are aware of. Others can use the space, but they have to get past you, first.
