I'm gonna write this down in case anyone ever reads this, probably not but still.

This is one of the three builds that I have for [Limbo] to actually make him viable in basically every situation you could use him for. One build is max range, other is minimum range and the last is big enough to be viable and not too big to be annoying.

I personally highly recommend the minimum range for anything except very specific squads because it is annoying as hell to have a big range [Limbo]. You might be able to use the Cataclysm build I made for Excavation in public lobbies if people like to hide in them, but that's it.

This is the minimum range build. Basically, if you ever play public squads with [Limbo], use this build unless it's Excavation. I insist on this because you can obscure teammates really well with a bigger than 30% range [Limbo]. This build is perfect for Defense, Mobile Defense, Survival, Excavation, anything really. It works with any mission even in solo play because it is small enough not to obscure but big enough to [Protect] the objective and the duration is also good. [Natural Talent] is used to minimize the risk of objectives or yourself getting hurt.
Cataclystic Continuum is not viable here because enemies inside a 30% range bubble are highly unlikely if it ever happens. The point of this build is therefore also to be a full support and does not serve any purpose other than shielding the objective or protecting yourself in solo Survival.

PS: Even Infested don't really get inside this bubble because once theres a few Chargers in there they basically block out the rest. Literally not even Infested fit in it. I speak from experience.

Edit 2022/03/28 - This build sucks. I have added [Primed Flow] for Energy Reduction Sorties, to not make it suck there. Can swap out when necessary. [Flow] is only necessary for that energy reduction because you don't keep enough energy to pop your 4. Either [Flow] or some modification for a little bit of Efficiency is required there.
