Wow thanks for the insight. Well if its just that im okay with it. I think thats correct jmerry, because i also noticed that the LESSER air, water, fire and earth elemental desciptions are not correct in the mage spellbooks. The normal ones are good.
All of those say " Eye of Stone - This eye absorbs an petrification attack casted on the mage" instead of the normal spell information. This is a rough translation from me, i did not found anything related to "eye of stone", could be an item of some sort -.-
So if its missing the spelldescription in the spellbook, it can also be connected to the scroll which is missing in the store. but yea, i have no idea - i not a modder.
However, maybe it will be fixed in the next version of scs. For now im good with that.
