While Clove’s self-reviving ultimate gives them a powerful advantage in VALORANT, they must also secure a kill or damaging assist to reap its benefit. One strange interaction with Killjoy’s Lockdown seems to nullify the kill/damage condition of Not Dead Yet, however, giving Clove an unfair advantage in some cases.
As showcased in a clip uploaded to Reddit, if Clove activates Not Dead Yet and gets detained in enemy Killjoy’s ultimate right after or at the same time, they no longer need to grab a kill or damaging assist to stay alive in VALORANT. Looking at how it cancels an essential condition, it seems to be a significant bug requiring Riot’s attention.
