Okay
1. Make a level 1 priest
2. Go the shortest way to the great sea
3. Swim out to fatigue
4. When the fatigue bar is done and you begin taking damage the level 1 ticks or w/e will let you heal your self, swim forward, heal your self, swim, heal, swim.... you are able to do this because since you are level 1 your mana will regenerate faster and you are taking less damage because of your low level.
Lemme know what you think
