i suggest making a faith build.... since its the easiest build to use.
this are what your stats should be when you are at SL 120
Start with Templar Knight
Vitality : 50 (As this build only really pours points into two other stats, you'll find yourself with plenty to spare leading up to SL 120 )
Intelligence : 18 ( For 3 spell slots and Second Chance )
Endurance : 50 ( Max stamina )
Magic : 10 ( To learn spells from Sage Freke )
Faith : 50 ( For maximum damage )
Luck : 7 (Don't ever increase it )
Weapons
Left Hand : Talisman Of Beast/God ( For miracles and spells )
Adjudicator Shield 5 ( For health regen )
Dark Silver Shield ( Good fighting against mages )
Right Hand : All weapons that can be blessed 5
Blessed Mirdan Hammer 5 etc..
Armor : Ancient King's Set ( From King Doran )
Magic/Miracles : Warding and Second Chance
Higher HP than most SL 120 PvP Builds , Excellent Magic Defense due to high Faith
18HP/s regeneration with a 5 Blessed weapon , Regenerator's Ring and Adjudicator's Shield
Reasonably versatile in melee attack style , like a Dex build
Damage is in part magical , so Warding is not much of a hindrance
Can use Miracles, non-scaling Spells and Melee effectively , No reliance upon weapon buffs.
I'd recommend that you increase the stats roughly in a ratio to those above, with a lesser emphasis on Faith until you've obtained a decent blessed weapon.
Try to cap Endurance reasonably soon, Stamina is the most precious resource in DS and it never hurts to have more.
Also, getting the Int and Str to meet the weapon base requirements is a given.
Get the Blessed Mace at 5-1 and Cresent Falchion at 4-1 at your game should be a breeze.
Oh and don't forget to grab the Mirdan Hammer ASAP at 5-2.
