Ironmouse Sprite: Everything We Know

The Ironmouse Sprite is a Mythic that regenerates health over time when you're low, granting Cloak and low gravity while it heals. It arrived with the v41.30 update as a datamined/rolling-out entry. It's Base-only and, because it isn't fully released, isn't counted in the 109-entry total.
Ironmouse is the newest Sprite to surface, a collab companion that showed up with patch v41.30. Here's what's confirmed so far.
Ability
Regenerate health over time when low. While regenerating, gain Cloak and low gravity — a defensive escape tool that turns being low into a chance to reposition. Healing scales 60 → 100 across levels.
Release status
Ironmouse is a Mythic found in Relic Chests (6,750 Dust to summon) with no variants. Because it's datamined/rolling out rather than fully live, we track it separately so it doesn't inflate your completion total until it's confirmed obtainable.
