Spell scroll of Lightning Lure
On the island used by gnolls to summon demons, the party found an unoccupied bunkroom in the southeast of the mountain temple, which Anrel unlocked using the Chime of Opening. There were four bedrolls to the south and a single bed against the northeast wall. While Anrel stood guard by a set of steps leading up from the northern corner of the room, Vichthart and Grokko searched the room.
Underneath the bed to the north they found a small chest containing Rrekkeh's journal, a drift globe, carved bones, and a rolled up piece of parchment, which Grokko unfurls and sees is a spell scroll of Lightning Lure, then passes to Anrel.
On 29 Thirkuoss, Anrel used the spell scroll of Lightning Lure while fighting Srir Silthallow, Rrekkeh Stormcrawler, gnoll cultists and several summoned demons at the summit of the Zaheer mountain temple. The spell did not work, and the scroll disintegrated.
