To get a level 212 you will need to do the following:
- Upgrade your Great Hall to level 10 FIRST.
- Get to level 199, do NOT go over.
- The xp for the hero at level 199 should be 3500XP or as close as possible without getting to level 200.
- Buy a gandalf training token (100 mithril)
- Use it on your level 199 hero. You will now have a level 212.
