How are the spell slots determined in the various spell lists? I was looking at the lists in the Guild Companion for February and was curious how people decide spell X is level 8 while spell y is level 10. I understand that many of the higher level spells are duration/range/# affected increments, but if you have spells: Open Door and Close Door, how do you determine which is the higher level one? Having created spells for HARP, there is a formula for spell creation. Is there something similar in RM? Thanks!
