Budding Crystal
The Hollow DimensionConfirmed block name from the Aug 7, 2026 marketplace changelog, which lists a fix so 'Budding Crystal blocks grow crystals' (implying it periodically generates more crystal growth, similar to vanilla budding amethyst). Tool/tier and drops are not documented anywhere public, so both are omitted. Image is a screenshot crop showing a glowing teal crystal cluster on a stone pedestal inside the Hollow Dimension; this identification (crystal cluster = Budding Crystal) is an inference from the changelog wording plus its visual similarity to budding amethyst, not an explicit in-game caption.
