Let's say I'm level 15 and have Lone Wolf. That'd mean I have 15 additional ability points. If I respec, thus losing Lone Wolf, will I also lose those extra ability points? Or would I re-acquire them if I were to take Lone Wolf again.

Also, as I understand, some skill books appear to only be obtainable once, such as Burning Blaze gotten after beating the boss in the church in Cyseal. Since respeccing makes you forget all skills, does that mean these rare skills are lost forever?
