As an aoe frost mage is having patience, we could give you the best tip about leveling (Mabinogi Gold) up. We leveled like 20-60 by aoe grinding and we enjoyed every moment of it. Nothing like having a group of people come by and just stand there and watch while you take out a huge group of mobs all at once especially when they get angry for you killing all the quest mobs they need. You do not have to have the best gear to pull off aoe blizz grinding in fact many wear green gear while doing it.
Every bit of mana and plus damage you can get helps but it is not 100% needed. Learn how the mobs in your area spawns and grind so that the group of mobs, once you take out the final group of mobs you first killed are already spawning again. Any questions just shoot us a PM or ask in the thread and we will try to help in the game.
