Intro: This is my personal guide and rules I go by when leveling. You don’t have to follow these rule, it’s just something I go by Mabinogi Gold. There’s really only one rule to follow, don’t be greedy.
I see so many 20’s and early 30’s trying to kill doggies all the time and then complain about dying a lot and need reviving because they will lose 10k exp if they don’t get revive.
Exp/Time: There’s a little tip to live by, stop trying to go for purple monsters. Sure it’s more exp. Pts. But this guide is for leveling.
The time I test by is per 30 min. You can set it at an hr or so if you want, but I go by per speed med. I can kill guardian doggie all day if I want and they provide a lot more exp but if I look at how much exp I’m actually getting in term of time, its about 10% / 30 min I could have killed Devil Troop for 20% / 30 min.
It’s more of trial and error at each level. So figure out what gives you the most exp/time. This is based on your own pace of fighting whether you use pots or water or not at all.
