I will hunt alongside you if it is truely dark elves you have spotted.
Can this get fixed with fresh and exact info?
If it comes to editing the script, it would be nice if there was a variable that consumables used that told the script how many spells that specific item can remove.
It may be CL for transparency, or a hidden variable for balance reasons.
One can always include it in the item description, right?
As for the live-cast version of the spell, it could well be the default value (three, do I remember correctly?) or use a reagent like the summon themes for stronger effect.
