I think I got most, if not all, listed here. Good luck with your new char.
- The disarm feat is useless on Layo, since the weapons creatures carry aren't droppable.
- Crafting wand and scribe scroll are not used in Layo. There's a more difficult craftingsystem for in place.
- The skills create armor, create weapon and such aren't worked with on Layo, since it has its own craftingsystem. It's only used for customizing the look of clothing or weapons, but the DC for that is so low, you hardly have to put points in it.
Next to this.. there are a few custom feats I think that can be taken always, but are actually specific to a class or race. So if you encounter a new feat, read the description well.
