Darksaber / Poison Spear / Bows

The Idea of this build is to debuff your opponent with the help of your weapons and crit them as soon as possible to death.

With the help of Poison Ivy you'll Poison your opponent when you generate spikes.

That's why you need a lot of Stones to craft Strong Stone Skin Potions. Trigger them earlywith the help of other Stone Skin Potions or Pestilence Flasks to trigger.

You need 45 Block to trigger your Block Potions so you'll play Leather Armor early to convert them into Vampiric Armor later on.
If you find Amulet of Steel you only need one Protective Purse to get 45 Block at the start of the fight to trigger the potions.

Your main weapon is Dark Saber. With a lot of Debuffs you'll get a lot of damage on this weapon. You want Mana to blind your opponent with it. 

Poison Spear is your best weapon before Dark Saber.

Belladonna's Whisper synergizes very well with it. More damage and even more poison.

Tusk Piercer give you Spikes and more burst damage aswell.

You'll need Strong Heroic Potions with a 3 weapon build. Especially against Shield Builds.

Smelly Wall generates a lot of Poison in this build.

It's important to buy every Lucky Clover you can finde because it's really difficult to gain Luck with this build and you want Nature Items for Poison Ivy aswell.

Use two Acorn Collars between your weapons to give them all a lot of critical hit chance. Very important.

Amulet of Steel can give you a lot of Empower in this build.

Amulet of Alchemy is really strong in big potions builds.

Moon Shield, Winged Boots and Cap of Discomfort can be very helpful defensive options.
