The DQ rules include a ritual available to all adepts that allows them to store spells inside of objects for casting later. This is under [32.3] Investment Ritual. Because there were essentially no limits placed upon what items could be invested with spells or how many invested items one could wield a set of rules developed over time in my campaigns. I've linked to the handout as a downloadable PDF on the Downloads page of this blog.
The costs for "investable" items were derived from the Shaping rules and also Rune Magics runestick materials.
Hope it is useful or provides food for thought for other DQ players.
