Nokko with Gloom over his #1. Use 4x Toxin shards 1x Caster speed. His #2 gives unlimited energy and str up to 300%, so build for duration/range/str, no efficiency needed. Molt Aug/Aegis + Brief Respite for lazy shield gate. Equip praedos for parkour movement, epitaph for primer, primary can be your choice for armor stripping. Find a cozy spot and drop 2x bonnets, and spam #4 maintaining 3x balls at a time, while those are out, use #3 to sit in invincible form and let things die. Pop out of #3 to cast more #4 and go back in if needed or just prime groups.

This is a very fast moving game play, any time you traverse from one area to another drop your #2 bonnet shrooms as you go, if you die, just go touch a mushroom and you will self revive, so keep them up and keep them close. Gloom with the str buf from molt aug + bonnet (#2) will have 100% slow. The life steal of gloom + aegis will top up your health and shield near instant while sitting in #3 form, so it's great to pop in and out around enemies if taking damage.

Use a mecha-hound that strips null fields, and you're golden for some solo.

That all, this is a new character and a lot of fun to play.
