Meta-Essence serves as Alice Liddell's primary source of regenerating both health and willpower. It can be found in some areas of each section, or dropped by enemies when killed. Meta-Essence released by slain enemies evaporates or degrades in a short amount of time. As it degrades, it transforms into smaller shapes until it finally disappears.
Meta-Essence appear as red, translucent, crystal-like structures with pale blue light shining from their centers and give a set amount of health and willpower depending on its size. In order of highest to lowest health and will:
Large heart Meta-Essence
Small heart Meta-Essence
Like the Roses in Alice: Madness Returns, Meta-Essence dropped by enemies is temporary, so it is recommended to pick it up immediately if Alice is low on health or willpower.
