Stat Distribution (Assuming Wretch):

Lv: 60,  VIG: 24   MND: base   END: 15  STR: 14   DEX: 37   INT: base   FTH: base   ARC: 20

Level up Strength and Endurance to match your weapons / shields.

This build aims to take advantage of the Hemorrhage status effect, by using a weapon like Reduvia and using the Ashes of War: Bloody Slash.

Putting points into Arcane will increase the blood loss buildup, because blood loss scales with the stat, ensuring that Hemorrage will trigger faster.

You may also want to put points into your Mind stat for spamming Bloody Slash.

Increase your Strength according to your weapon's requirements while also increasing Dexterity, as many weapons that inflict Bleed also have Dexterity scalings as well.

However, keep in mind that there are enemies who are resistant or even immune to Hemorrhage. Having a weapon you can rely on without causing bleed build up, such as one with decent Dexterity scaling, will make your build much more versatile.
