The Rift Guardian - [Limbo] | 0 Forma Builds
This build is for cheesing mobile defense missions and helping to [Protect] your defense targets during sorties.
The two main skills you'll be focusing on during these missions are:
Cataclysm - This skill creates a large dome that's centered on your crosshair that shrinks in size over time. The dome causes all players, enemies and objects within it's area of effect to be "rifted". Attacks from outside the dome will not affect those within and vice versa (with a few frame abilities as exceptions).
Cataclysm will also prevent all players from interacting with objects, such as mobile defense consoles and hacking consoles. Therefore, this skill should only be used after object interactions are complete.
Stasis - Pairing this skill with Cataclysm causes all enemies that enter the dome to be temporarily frozen in time. Cataclysm + Statis combo is an exceptional CC and Survivability utility allowing by stopping all enemy targets within, preventing them from moving or attacking.
TLDR; Run to objective. Interact with required object if necessary. Pop skill 4 and skill 2. Dance a while. If there are nullifiers, run out and kill them then come back to dance.
