Using scrolls of spells you can't cast

[leo1925]

When you use a scroll of a spell that is on your spell list but you can't yet cast do you have to have a high enough casting stat?
For example a 10th level wizard trying to use a scroll of wish, does he have to have an INT if 19 or not?

(I know about the caster level check needed to use a scroll in the above way so there is no need to focus on that)

Yes.

Both a 10th level and a 20th level wizard will need that Int of 19 to cast Wish from a scroll.

You are free, however, to attempt an UMD Check with a DC of 34 to emulate said Int score.

You are correct, i re-checked and i don't know how i miseed it.
Another question, does a temporary bonus count for meeting the prerequisite?

A wizard can prepare a 9th level slot with a temporary ability score, so it should work fine for a scroll.

That said, the UMD check to activate the scroll may be high enough to emulate that score anyways. 1-5 spells the ability score emulation is harder than the scroll activation, they're even (dc31) for level 6 spells, and scroll activation is harder for 7th level and higher.
