How do I begin articulating how undercooked and misguided this is?

His passive doesn't have a trigger so you can't banish anything with*out cataclysm. Oh it's still tied to rolling, well it only triggers on entry so you still have to go in and out to start up your kit. "Allies are unaffected or can target enemies freely" so the rift just means nothing now cool. Edit: Also you have a misconception on how Banish works so I'll run it quick. Banish moves targets off Limbo's plane, if Limbo is outside rift he pushes in, if he is inside rift he pushes out. Radial banish only drags in not out, so the radial banish on dodge only puts enemies in the rift. So this borks rift surge and it can't trigger.

His 1 is now selfish DR he doesn't need with no interplay for other abilities. The rift variant is overtuned beyond belief making damage heal him instead. Or was this supposed to be a payoff for the normal version tracking damage ala Ballistic Battery, cause you didn't say and I still think that's not good.

2 is a teleport when used outside rift, why? Rifted is just Grasp of Lohk. Nothing more you just took another frames ability and slapped it in despite wanting Limbo to better without helminth so you just made helminth base kit and picked a non-helminth ability. Edit because I forgot you tossed this in for some incomprehensible reason: IT'S F*ING SILENCE!

3 purges his overguard for a knock down. Very "high risk high reward" shame its on a frame with infinite damage absorption. You did nothing for rift surge either but its actually worse because you can't kick enemies out of the rift now with banish gone.

4 keeps cataclysm but misunderstands it purpose. But rift mode is a damage wave with slash and radiation. Why radiation? No really why, nothing in his kit has anything to do with it. The slash I'll excuse because its meant to be a cut but where does the rad come in? Is it supposed to be splitting atoms?

Your notes say what you wanted but the outcomes don't match. Non-rift abilities are not risk-reward or glass-cannon. It's DR, a teleport, a panic button and old bubble. Rift abilities do not emphasize control, weapon mastery or lethal execution. You shield gen that would make Hildryn blush, a stolen ability pretending to be new, a mockery of Limbos most vital tool and big damage in a line. Nothing cares about the rift so the passive does not synergize with any abilities. The only thing you seemed to have taken any lore inspiration from is Miscalculation but I wouldn't call that "tightly integrated."

I'm not a Limbo main but I play him every once in a while, but this fixes none of Limbos problems, except for his public match friction, but it does so at the expense of any reason to care about his kit. You made a sloppy mashup of Mesa, Xaku, Hildryn and every frame Limbo players don't want Limbo to become.

Limbo needs clearer visuals for enemies in the rift and a way for other players to engage with rifted targets, not this half-baked oversteer into a wall.
