The bread of the build is the weapon passive: you'll need any weapon with the Gourdo's Community Garden skill, I usually use the Basherball since strikers have the highest weapon damage (for other effects).



You see, the passive deals up to thrice your healing in damage, as long as you heal at least 11hp. That damage will help you fill up your skill stacks. Powers that heal on-damage will trigger on the weapon's passive damage, and that healing might trigger the weapon again, leading to funny interactions with other abilities. The more enemies near you, the longer you can hold your skill, and more hits will pop on your ears, so this is best for hunts like Blisterbane Bog, Molded Grave, and maybe Splintershard Cavern.

The butter of the build is our armor: The Wollusk Helmet and any chest piece that creates acid pools. Wollusk Hauberk spawns large and short-lived acid pools on dodge, so it's easier to keep the acid going. Gloop Top Glaze spawns medium/small and long-lived pools on kill, allowing a better pairing with Colossaphire Greaves (Gloop Top also might kill allies summoned by powers that trigger on kill). If you have a friend to create acid pools for you, or you're hunting on Molded Grave, you can pick Bullrog Gauntlets for some more damage.



Wollusk Helmet heals us for up to 70% of the acid damage you take, and acid deals on base 30 damage, that's 21 healing. Not only that, but since you can't heal at full hp, the acid ticks helps you keep the healing going.

And that's the gist of the build: summon acid pool->stand on it->praise the gourdo->???->profit!

Important details about using this weapon:

• The weapon's passive counts as an Attack, but won't count as Light nor Heavy;
  
• The weapon's passive won't count as attacking;
  
• The weapon's passive can't focus hit;
  
• The weapon's passive can't crit but it might trigger damage powers that can;
  
• The weapon's passive counts as your damage, so it can refill the skill if you deal enough damage;
  
• The weapon's passive counts as a hit for hitstreaks;
  
• The acid damage will break your hitstreak often (you can make hitstreak powers work with Attack Dice and enough enemies tho);
  
• The acid damage triggers any power with a "take damage" condition, good or bad;
  
• The acid damage will break shields;
  
• The acid damage doesn't count as your damage (or anyone's else) Player acid now counts the respective player as its source, thus refilling your skill and counting for hitstreaks;
  
• The acid will affect allies, players or not. Player acid will only affect players using the proper gem;
  
• Player acid stacks with hazard acid, thus increasing your damage input and output;
  
• The acid damage might trigger Deus Ex and instantly kill you.

Well, you got your hands occupied, and you might be running around in donald the duck fashion, so you're left with the legs to cover up, lets go over the trouser tier list:

Gourdo Weapons have 2 sustain and 1 support slot, but I'll give advice on damage gems just in case, although I recommend you to focus on the slot buffs.

These two builds are the ones I use the most (Sometimes switching legs with Quetzi Waist Guard).

This build works best on higher super frenzies, but also has way less room for customization, you'll need the following armor combination:

And the following gems:

The reason being that you'll need as much healing sources and healing increases as you can, and you'll need a way to compensate for Ribbat Surcoat's teffra consumption (Which also ends up being a teffra source). I picked bow here because it has better attacks than strikers, while having the same Weapon Damage stat.
With this build you'll have to dodge some hits early on, but might end up just spamming the skill on later rooms. Although gourdo's passive doesn't crit, it does trigger dice, which crits. So if you get Morale Booster, Attack Dice, and some crit source, you'll become nearly unkillable.
