In the previous game, there was an NPC sorcerer you could talk to in order to reset your skills. This time, there’s a magic potion. The respec potion is very rare, so it would probably be a good idea to snag it as soon as you see it, no matter the cost. It might be pricey, but having it on you will allow for some peace of mind.
Once you drink it, all of your skills will reset, and all your ability points will go back into the “available” pool, including the ones you got from Places of Power. You will then be able to invest them any way you like, again.
Potion of Clearance
The first vendor that sells the Potion of Clearance is Keira Metz. After finishing the Magic Lamp quest, you’ll start another – An Invitation From Keira Metz. Go to Keira’s hut north-east of Midcopse, and ask her to trade. You’ll see the potion in her inventory. It costs 1000 Crowns, and lets you redistribute your ability points.
