Pestigoon - A Nurgle-inspired build (Wrangler Difficulty Abyss 90+)

This build was actually created flavor first - inspired by Nurgle, Chaos God of Pestilence and Decay. But it turns out the blessings of Nurgle enable his followers to conquer the abyss.

Skills and Perks

Recovery Vault - Simply attack to heal. Grandfather Nurgle keeps his followers alive to revel in his glorious diseases.

Funky Flippers & Miasma - Adds damage ticks around you and your clones that help deal with high armor enemies. And can kill weak enemies just by standing around. Share the gift of pestilence with your enemies!

Dripping & Sticky Strike - Use Dripping to cover your enemies in slime to slow and damage them. Adds a ton of damage ticks when sprayed onto bosses. Can consistantly keep up 5 slow stacks for a 125% damage bonus from Sticky Strike. Exploding your clones with your secondary skill can add even more slow stacks for up to 10 stacks - 250% more damage! Do it like a Beast of Nurgle and give your new friends a slimy hug!

Catalyzers

Fire rate is extremely important to both heal and spread slime as quickly as possible.
Feel free to replace some of the hp stuff with whatever you like to maybe boost speed/damage/armor. You usually do not need that much hp - but it just feels right for a demon of Nurgle to have bloated hp numbers.

Gameplay flow

For large numbers of enemies or when you have to defend an area, jump into the air and attack from their to spray a larger area with slime as to control the field and spread damage all around. Get close to tougher/healing enemies so they actually suffer your miasma damage. Explode your minions for damage bursts as needed.

For bosses, you actually wanna stick to the ground where possible so your attacks spawn damage puddles to boost your dps. Explode your minions whenever your secondary skill is at max charges to keep up maximum slow stacks.
