Stat Distribution (Assuming Wretch):

Lv: 60,  VIG: any   MND: 30   END: base  STR: 14   DEX: 18   INT: 37   FTH: base   ARC: base

Level up Endurance to match your weapons / shields.

This build prioritizes 3 different stats, although your main stat will be Intelligence as your main source of damage.

Strength ensures you can wield the weapons you need, while Dexterity scales well with certain weapons, such as Moonveil and Crystal Knife.

More Dexterity also means less casting time for your spells, so you can cast more spells for less time than pure Magic builds.

However, since you are not running a pure Magic build, we are compensating the lack of damage for what we can deal with a melee weapon.
