Not sure if there any any specific you expect but yeah there a plenty like:
- Adrenaline gives 2 ap in the current turn but removes 2 in the next one.
- Teleport has had its ranged reduce and cost increased to 2 ap.
- Bless now costs a source point.
- Executioner only procs once per turn.
- Certain spells have a higher minimum requirement (in terms of skills spec)
- Skill crafting (although it's more crosspath skills than skill crafting but it's cool anyway)
And not everything has been announced and I am probably forgetting a lot so... Anything specific in your mind?
