Final one I can confirm for now:
Here is the hopefully complete list of new KIs and their triggers:
Siren - Teles - VoidCrystal x3, Voidsnapper x3, Siren's Hair x1, Maiden's Virelai x1
Galu - Zerde's cup - Voidweed x3. Ashen Crayfish x3, FlanMeatx10, Black Pudding x1
Naraka - Vinipata's blade - Voidcrystal x3, Duskcrawler x3, BoneChip x10, Scarletite Ingot x1
Catuare - Schah's gambit - Voidsnapper x3. GravewoodLogx3, Leisure Table x1, TrumpCardCase x1
Mandragora - Albumen's flower - Ashweed x3, Voidgrassx3, Vermihumus x1, Coalition Humus x1
Sandworm - Onychophora's soil - Voidcrystal x3, Voidgrass x3, Titanite x10, Worm Mulch x1 (?)
Amphitere - Erinys's beak - Voidsnapper x3, Ashweed x3, Mistmelt x1, TornadoScroll x1
Everything is personally confirmed by me but Sandworm. Worm Mulch drops from Ziryou or Pulling the Strings BC.
Has been a long day of looking at JP text and shuffling items. Everyone have fun getting tormented by the new NMs !
