The most likely answer is that there isn’t a confirmed Elation sustain yet, and the current discussion points more toward Nihilux or Pearl as future candidates than a settled, official choice. Some community guides and leak discussions suggest Elation may not get a sustain at all, while others speculate Pearl is the more likely Preservation-style option and Nihilux could fill a different support role.
What’s actually known
At this point, nothing official confirms a dedicated Elation sustain. The strongest public claims are still speculative, and they do not agree on the exact role of the rumored characters.
One recurring idea is that Pearl would fit a sustain slot better because she is repeatedly described by community speculation as the more probable defensive option. Another line of discussion says Nihilux may instead act more like an Elation MC replacement or a broader Elation support rather than a pure healer or shielder.
Why the confusion exists
Elation is being discussed as a newer, synergy-heavy path, so players are trying to infer the missing pieces from leaked kits and theorycrafting. That leads to a lot of overlap between terms like sustain, support, and defensive utility, especially when people talk about future mono-Elation teams.
The current Elation Trailblazer discussions also make it sound like the archetype is being built around damage amplification and team synergy first, not around a clearly defined healer or shielder right away.
Most likely takeaway
If you mean “who is the Elation sustain supposed to be,” the honest answer is no one confirmed yet. Based on the current chatter, Pearl is the safer guess for a true sustain role, while Nihilux is more often framed as a support or path-defining unit rather than a dedicated sustain.
Until there is an official reveal, any answer beyond that stays in rumor territory.
