Edition notes

In Java, brew a fermented spider eye straight into a water bottle. Bedrock also accepts it on awkward, mundane and thick potions, and corrupts Strength II into Weakness. Keep some ready when a zombie villager shows up: Weakness plus a golden apple cures it. Added in 1.0.0 (Beta 1.9-pre2).
