go with limbo.

Try to get as much duration as possible and range should be 100% or lower.

You get lower range and higher duration via narrow minded, but if you don't have that, just focus on duration.

As aura, if you have corrosive projection, use that. If not, I guess any will do.

Take really good status +critical weapons with you, at 40 min +, pure (critical) damage won't cut it.

Make your energy color greyish darkish, just not white or anything neon.

The way you will play is, load in, "roll", reach location with kuva (former survival) module, cast stasis. cast cataclysm. Kill annoying enemies before recasting stasis so you can time stasis well and how it suits you. Roll out of cataclysm into the rift to pop cataclysm and cast it again on the spot you need. Only cast cataclysm while stasis is active. Limbo is squishy.

Pick up lil "kuva battery" while you are inside the cataclysm, don't pick up any that are very close to a life support our you'll activate life support.

Make sure to not cast cataclysm anywhere that isn't on top of the survival/kuva harvester/module. Your job is to cast stasis/rift around the harvester. And stay in the rift. Always stay in the rift. Revive your team mates and if you feel like leaving the rift only do so as the op.
