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.
Poison Spear needs as many active stars in front to destroy Block.
Your main damage weapon in lategame is Darksaber. With a lot of debuffs you'll get a lot of damage on this weapon. You want Mana to blind your opponent with it so Moon Shield help with Mana at the start of combat.
You'll need Strong Heroic Potion with a 2 weapon build. Especially against shield builds.
Smelly Wall is the best skill and generates a lot of poison in this build.
It's important to buy every Lucky Clover you can find because it's really difficult to gain Luck with this build and you want Nature Items for Poison Ivy aswell. Blueberries can generate luck if you have over 10 Mana.
Use two Acorn Collars to giveyour weapons a lot of crit 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.
Winged Boots and Cap of Discomfort can be very helpful defensive options.
If you can generate a lot of Mana you can try to trigger Mana Orb. If it can happen you could use Djinn Lamp for extra damage. Very late game scenario!
