Is there any one out there who is really had an experience in using a spellhowler can tell me exactly what is the best combination for combining a tatto coz my current set up of my tatto(sorry if i didnt spell it ryt^^) is
Con + 4 Str-5
Int+4 Men-5
Wit+4 Men-5

is this a good combination? coz im kinda not satisfied with the attack that is given to me by my spellhowler im using a +6Homo and an avadon set
with out a buff of empower my Matk is 770 but with a buff it is 1772.

You're ok with dyes.
But try to get the +4/-4 ones, from mammon, they're not cheap. But you really need then, you'll start to feel the lack of men when receive debuffs.

You just need a better weapon and you'll get a good M. Atk. ^^

Yep...you are ok with dyes.
Like Vawned already said...swich them with +4/-4 .
Your matk is not ok?
For PVE you can use this combination
+4INT -4MEN
+4WIT -4MEN
+1INT - 2MEN
but only for pve and use btm and cdl.Anyway...the one that you have is the perfect combination for mages.
Huh...and always use buffs like empower and bersek on SH.
For PVE you can use Demon's set for more matk (+4INT)....but it has no cast speed....so go to some areas where you can CDL.
For weapon...since you are already B grade...skip SOW and try to get SOM.
You will be ok .

you are in avadon so, 52+
try to get a wizard tears instead of your homu +6
homu+6 : 128matk
wizard tears clean : 132 matk, 141 with +3
you can also buy a valhalla (122 base, 131 with +3)

as i always suggest
dont use cast spd sets if u want dmg output(for farming)
use at least demons set with +4 int and with the +4 int dyes u will see the difference
if u want better dmg output use cdl
another option is droping even more ur cast spd(wich is not a big deal since u have LOW cast spd) and use +magical power weapon

my personal suggestion:skip b grade
ppl say u save money by buying only 1 shot instead of 3 and u can carry more
thats true!but if u want to do it that way dont craft a weapon-just buy shadow weapon
and the next step is SoM

Yeah, Demon Sword and a Ecliptic Sword (Better than SoWD) with Magic Power it's good.
