I've had alot of luck with my 24/12 build (30). It ultimately will be a 24/15 build (34), once i've loomed every scrap of what I use in battle.
IF 8
PS 8
SH 4 (eventually 5)
ATH 4
RID 1 (eventually 5)
WPM 4
1h Prof 121 (138 eventually)
no other proficiencies
Slow, but powerful. shield skill is nominally high, but a heavy shield is necessary, one with a lot of hitpoints. I personally use a spathion and heavy heater.
you will not outstep someone, but blow for blow you can match 2 handers and heavy polearm, and do quite a bit of damage. Its almost mandatory to carry a secondary weapon with this build, I carry a warhammer; its length or its lack thereof is an advantage with the spamminess of the 1h build. finally, to top it off, i carry a dagger (116 speed) for all these shielder and dagger spammers, and for pole spammers. oh, and mobs, it works wonders
The only problem with this build is that it is relatively slow, with weak shield skill. you'll eventually have to manual block, and at that point you'll be sort of a duck out of water.
