I've just noticed a peace pipe too, that looks handy for a little bit of reduction?
Any reduction is welcome, but keep in mind if you can give it other uses with other chars to justify the zeny spent.
Also keep in mind the advice regarding the Homun, Since Amistr cant dispatch mobs fast you'll be in danger so is also wise to choose a spot with at least another AFKemist nearby. Chances are the other Homun will take some mobs off of you too.
Leveling in OD2 is like real state: Location, location, location.
