Necromancer spells: Conglaciation of Bone, Gangrenous Touch of Zum'uul

[baonecroman]

Conglaciation of Bone - Wiki says it is currently 'bugged' and suggests as Chardok drop, I assume it means it is not dropping due to bug?
According to Allakhazam, it drops from Velketor's Lab
The earliest date of Allakhazam comment is 2003, so it may not have dropped during Velious era and thus should be removed from Wiki


Gangrenous Touch of Zum'uul - I see some WTS on search around time when Chardok revamp was released, I suppose this has been removed? It looks like earliest comments on Allakhazam is dated post Velious, ie end of 2002, and seem to be the reason. However, it shows that it is 'Kunark' expansion on it, so this could just mean the location

Can I assume these two spells do not, and will not exist on P99?
