This build is focused around [Rift Torrent], an augment for [Limbo] that can be obtained from Cephalon Suda or the Arbiters of Hexis. The mod at base is incredibly powerful, especially for solo play. This is the most effective build for [Limbo] in terms of killing, keeping casts up and staying alive.
Our huge range is to get as many enemies inside cataclysm as you can, let them wander in and then use stasis. [Overextended] does take away a bit of strength, but having more enemies inside your cataclysm makes up for it, because your Rift Torrent multiplier will be able to stack more. Your damage will be incredibly high and you'll be able to easily one-shot enemies that you couldn't otherwise. You'll also be getting a lot more energy as enemies are killed in the rift, as detailed below. This is important due to the efficiency of the build as recorded above is negative.
Power strength mods are in order to increase the base damage multiplier on [Rift Torrent]. [Blind Rage] can be replaced by [Augur Secrets] for better efficiency if desired, as your abilities will be quite expensive with the negative efficiency from [Blind Rage]. Casting [Rift Torrent] takes a lot of energy, even with [Limbo]'s energy passives factored in (He gains 10 energy for every riftbound enemy killed, in addition to him and his team regenerating energy inside the rift). If you do go along with this and replace [Blind Rage] with [Augur Secrets], consider to replace [Augur Reach] with a duration mod like [Constitution] or [Augur Message].
Exilus mod here is written down as [Cunning Drift], however this will require a forma. It's absolutely fine to not use this mod, however, as your range will still be more than sufficient. [Power Drift] is also a very good choice for this build due to increasing power strength. Either way, pick a mod that you like for this slot: I personally like to use Mobilize a lot to aimglide longer.
As always with Limbo builds, be wary of nullifiers in Corpus/Corrupted missions! They will instantly cancel your cataclysm which typically leads to your death.
