With the addition of Overguard, we’ve updated the scope of which abilities are considered to be crowd control. Note that these abilities will still do their intended damage -- it is only the crowd-control effect of the abilities that won’t apply while Overguard is present
　（中略）
　・Limbo's Banish
　　　Eximus ignore the knockdown effect of Banish while Overguard is active,
　　　however they can still be sent to the Rift plane regardless of Overguard
　・Limbo’s Stasis

Limbo’s Rift & Eximus
Limbo can still send Eximus to the Rift plane where their damage will be avoided, but Eximus Abilities will now ignore the Rift plane.
　　・Originally this Workshop listed ‘Limbo's Rift & Cataclysm’ to now be considered CC, but this was not an accurate description. Limbo can still send Eximus to the Rift plane while Overguard is active.
