Solo/Duo NightmareI tested the build with many variations, and on Nightmare difficulty this proved to be the most reliable and most stable setup. While it holds its own even solo, the true potential of the abilities is especially effective in Duo. The synergy between the gear and abilities guarantees constant damage and almost indestructible survivability.+446

One Man Army(Latest update: Version 0.2.0.4) This build focuses on the spells and their synergies as well as your jokers. It shines the most whether solo or co-op not only due to its ability to clear hordes easily, but also with its ability to keep yourself healthy. I have tried and tested this build in both Nightmare and Very Hard difficulties with my personal record of 2,812 kills, 84,000+ damage, and 70,000+ EXP (shotgun and revolvers combined) on Nightmare difficulty so far. It is really up to you on how you will use the spells but! I recommend you use Wisp first, shoot it (using the revolvers) to make it blue, activate acid rain on where most enemies are, and use Blizzard last. Watch the spells take out enemies before you can even say "Yeehaw". (Feel free to swap out Helping Hand joker with any).+23

Aiming Burst🎯Quad Cylinder & BowJoker Aiming Burst got some interesting changes and feels really fun to play now.+21
Poney's High Sustain Quad CylinderIt's the setup I’ve been using for a long time now, both in Solo/Co-op, up to Nightmare. Thunderstrike and Rain for wave clear and regain lot of health. Doll for emergency, or to revive teammates. Bottle Crate for emergency healing, or to help teammates. Quad Cylinder with a speedster build. Move fast, shoot fast, jump high and never run out of ammo with Ammo Supply. With this setup you are the one who will survive, the one who will never disappoint.+15

How it plays

Playbook

The Acid school's big curtain call. Rain calls down sustained acid across a wide area for its full duration, layering corrosion on everything caught underneath. It's not subtle and it's not fast to recharge, but nothing else in the school covers this much ground continuously.

Strategy

Drop it on objectives, doorways, or boss arenas where you know enemies will be forced to stand still. The sustained damage is most effective when targets can't leave the area. Combine with Contagion beforehand to maximize the debuff overlap.

Strengths

Widest area coverage in the Acid school
Sustained damage over duration rather than one burst
Extremely effective on objective-based encounters

Weaknesses

Longest cooldown in the school
Moving enemies can walk out of the rain area
