They want you to bruteforce their bad stats through equipment. And even then her dex is hilariously bad for a trickster cleric.
Why does she need dex?
She can use only light and med armor. Both these types add dex to ac, in her situation - substract. There are 2 ways: take heavy armor feat on 4 lvl, then you lose +2 wisdom, so lover DC and accuracy with spells, or add 1 dex on 4th level, and so you still lose +2 wisdom. I also think, 9 dex should be changed
