@daermadm Not sure i follow, if i’m a straight up level 30 wizard, and i cast a ninth level spell sphere of ultimate destruction, its going to do 60d6 (with no small penis damage caps), and assuming a failed save.
Now i make a, Wand of Ultimate Destruction, CL30, 9th level spell Sphere of Ultimate Destruction, that does 60d6. Just as the same wizard cast it earlier, but now in wand form.
The 30th level caster doesn’t want a CL29/Spell level 15 affect, they want a CL30/Spell level 9 affect, the ‘why’ this caster would do that is really irrelevant, if for any other reason than to be difficult.
Which cube would i use from this table?
