Hi,
In Unspoken Word 2: Thieves Arm Jeff Khyer wrote up heroquest for the Sandals of Darkness.
In some ways it saddens me that these lovely details of Glorantha have been lost in the pulp cults produced in CoG 1 and 2, which are so hugely in need of a massive overhaul.
I did piddle around with rune casting but I have given up and gone for a retro feel 'Common Magic' Skill, a bit like the old Spirit Magic and Battle Magic skills, however I have specifically restricted magic to those available from the cult or associates. I have allowed the players to use Pact points to gain the benefits of the cult runes as if the had intergrated them. However as Greg always says, Your Glorantha May Vary and this works for my players.
