Gothic 3 Problem finding spells

I'm level 28 with 110 ak. I've located 4 shrines of Innos. They all provide flame sword, flame wave, banish evil, fire rain and heal other. I've located 7 shrines of Beliar, all providing amnesia, bloodlust, summun skelly and demon and soul travel.
Where the heck is fireball and lightning? I've tried learning the above provided spells (the ones i have enough ak for) in the hopes of opening new ones at the shrines, but none ever appear even after sleeping or visiting another shrine of the same god.

Hmmm ... I'm trying to recall where I picked up fireball - I think it might have been in Ardea. Gawd I love that spell ... except when it misses

Lightning I think was outside Montera, right after the rebel camp on the corner.

Did you check for the advanced spells?

IIRC, each shrine has two groups of spells that it gives - sounds to me like you're only checking one group.

I got my Ligthning spell in the Beliar shrine nea Cape Dun... Try there
