i'd like to try this, but got some questions

because of the 55 base int, i think i'll have a nice amount of mana or should i go for like 70 int or more/less?
with clubs, should i try to keep the dex/str equal or is 80 dex enough?

any other advices are welcome^^

Honestly depends on how much fg you're looking to spend, but i think a good balance would be:

65 int Statted first
No vita
90 str after gear
90 dex after gear
60 hm after gear

this should breed for a nice hybrid, so stat your dex/str however you can to get them as close to 90 or 100 as possible, and then make sure you get AT LEAST 60 hm on your gear.

I'd agree, and you really want to work that dex/str early on or else your levels will be slow. Should get full chains easily though, just might be a little slower than the other classes.
