Event Unique Potential Scrolls

Used the first one on my lvl 130 Katara and worked, however it got 9% int and % avoid

Used the second one on the dagger of the same char, worked, however it got 6% int

For the love of god, why is it so easy to get INT potential?

Used on my Ele staff 7, 15% luk, 6%int
