The Lingering Potion of Regeneration (II) creates a lingering cloud that applies an intensified Regeneration effect to players and mobs within its area of effect for 5 seconds. This stronger effect restores health at a faster rate over a shorter duration. It is brewed by combining a Splash Potion of Regeneration (II) with Dragon's Breath in a Brewing Stand. This potion is especially useful in intense combat or critical moments where rapid healing is essential. The lingering cloud allows multiple entities to benefit from the powerful Regeneration effect, making it a strategic tool for group recovery in high-stakes scenarios.
