A few notes to spell scrolls:

• The most interesting part about spell books is the fact that you can trigger the effect from Sun and Moon with the Warden or Templar. The Warden has a cold tree but no fire, and the Templar has a fire tree but no cold. If you have for example a codex with a fire skill and use it with the Warden, you get the cold bonus from Sun and Moon ! This enables a lot of new builds for both classes.
  
• If you have the skill in a skill tree and you cast the corresponding spell scroll or spell book, then the level and all passive skills in the skill tree will be used.
  
• You can actually use 7 (or more) skills at the same time (and still gain their passives).
  
• The cooldown of the scroll may not be lowered by cooldown reduction.
