IMD (Instantly Mine Deepslate)
IMD is a lightweight, no‑nonsense datapack that supercharges your deepslate mining experience. Whenever you’re holding a Netherite pickaxe enchanted with Efficiency V and under the effect of Haste II, IMD automatically bumps your mining_efficiency attribute to 30, letting you break deepslate in a single tick. Remove either Haste II or the enchanted tool, and your efficiency resets to its default, ensuring balanced gameplay.
