Djinn duels, also known as Cagliostro Duels, are often settled medicinally where each djinn brings three pills, two of which are harmless, but the third containing a dimunuendo binding. Each one is swallowed in turn. The first person who swallows the pill with a dimunuendo binding shrinks and becomes the loser. Such nature of the duels are likely due to the Blue Djinn's decrees against open confrontational destruction, which allow them djinn duels for a less violent way to settle disputes. In the nature of djinn duels, it is largely determined by luck, something the djinn have strong influence in. Nimrod has fought and won one of these duels against Ramjus, an Ifrit.
