rosary
if you do not have those accesories xDD that give you 40 str more (I do not know the name)
I think that there are many cool build taking care as equipment, If you use a Alice like Pet this gives you mdef + 1 I think so.
In my server there are a Flower that can be equiped on the upper + a gibbet card this gives you mdef + 20
you can put a sungalsses with gibbet mdef + 5
My paladin has Base Int 33 and the server rate is 5x5x5
mi equipment against magical atacks is
Dropping cat = mdef + 15
ragamuffin = mdef + 10
Valky shield + seeker = mdef 15?
shoes of a bride = I do not know the correct name but these give you mdef +10
accesories = x 2 Total mdef = 10 rosaries without slot
weidding dress = mdef + 15
endure lvl 10 = mdef + 10

mi amount total of mdef using this equipment is = 85 + 40 I think so.
Most of scholars jobs make me a damage below 100 per hit. I mean A cold bolt has 10 hits 10 x 100 this give a amount total of damage of 1000 per bolt.
Making probes in the same server but in the test server I discover that 100 of Mdef + Bonus the most of Mage class miss you their attacks.
You are totally vulnerable to Physical atacks but this is very helpful to magical atacks.
I probe other build without mdef very helpful too. Bolts make a damage of 70 being generous with any mdef in your build.
This was a Dokeby card in your armor valkyrya armor with thara
Scuba diving mask
tidal shoes
you should switch your garmet between marse and jakk card and dustiness card
the point of this build is to consume a fire resistant potion.
If you have a dokebi card in your armor you are very vulnerable to fire magical atacks for this reason you shueld consume a fire potion. The only atacks that can cause a great damage is Earth property.
There are other Godlike accesories that give you mdef + 8.
