Actually, the "Orb of *" spells aren't ray spells.

Incidentally, this allows them to work on tarrasques.

hm.. good that we arent that strict looking at that

well then exchange the spell to "Enervation", doesnt do that much damage then but with a nice empower it does also hurt a bit 2-4 * 5 HPs due neg LVL

for some additional spell pimpinmg add empower or instead of the empower a maximize does also add in some extra fun, of course even better to have them all

two jucie rays which deliver a neat lot of neg level and it is only an 8th level spell slot needed

of course twin empower split ray sudden maximize Enervation does even do more fun
