Dawnport Testing Vocations
Solution 1:
No. You'll gain 5 life, 5 mana and 10 Oz (capacity) for each level even after level 8.
Attention: If you go to the main land above level 8 as a Knight you'll have lost 10 life points and 15 Oz for each level. Only level up above 9+ in dawnport if you want to keep you character there.
