Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

Some days ago I got the feat and the 9th circle spell is sacrificed alright, but I can't drag the feat anywhere and I can't click it.

I assume there must be others who use this, so if anyone could tell me how to turn it on, I would appreciate it :3

In the Quick Cast menu there is a Spontaneous Conversion button

You, sir, are a gentleman and a scholar. Thanks!
