Reading through the class, it seems to imply that you can't get to the higher levels of your curse until later levels: "At higher levels, you can cast more revelation spells, progressing your curse to its major stage and then an extreme stage; these stronger curses are cumulative with the effects of the lower stages and can alter them."
If I'm reading the abilities right, though, you could do it at level 1. Does the following work? I cast my focus spell and hit the minor curse level. Then I refocus and go back to two focus points. After doing that, I can cast two focus spells with the two points available and move to moderate and then major levels of my curse?
I ask if that's possible, because the major curses seem pretty powerful for level 1. Especially the idea of walking around with a 4d6 fire aura that causes 2d6 persistant fire damage from the focus spell while being concealed from everyone.
