Nai'Shedareth
It was a ritual duel between to priestess of Lolth, where the resultant victor is presumed to be the most favored by the goddess. The priestesses can chant a prayer to Lolth, if no manifestation of the goddess could be summonned— meaning that none of them had her favour— they would be summarily executed. However, if the goddess responded to the prayer of one of the priestesses, she was accounted the winner and could demand death, dethronement, or worse for her vanquished rival. So far, only one instance of it has been shown, when Shakti Hunzrin challenged Liriel Baenre. Liriel accepted the challenge, and having become a Zedrinset, killed Shakti's snake whip and sent her to the Abyss.
