The agondray is a standard unit of measure for magic. It is abbreviated Ag. The conversion factor between agondrays and kigamms (the metric measurement) is 1.7/1. (That is, there are approximately 1.7 agondrays in a kigamm.) An experienced wizard can cast spells of about 29.4 Ag heavy, if the wizard can master all elements in the spell and each element in the spell must be mastered by at least one dragon the wizard is bonded too. Wands of the right element can strengthen the spell with another 5.58 Ag.
