Overview

Ova are tied to a major story-progress system. The Gloom Siphon can send them onward, and the more Ova you recover, the better their odds of survival.

What The System Does

Ova are not ordinary pickups. They are tied to survival odds and story progress, so treat every Ova-related prompt as a route decision.

When To Send Them

Do not use the Gloom Siphon casually. Check nearby routes and optional objectives before choosing to advance this part of the story.

Why It Matters

The tutorial language links Ova recovery to survival odds. That makes Ova a natural checklist item for completion-focused players.
