Ghast Tear

Ghast Tears are items dropped by Ghasts when they are killed. They are relatively difficult to obtain due to the fact that Ghasts commonly hover over lava or unreachable areas and that Ghasts only drop 0-1 tears.

As a brewing ingredient
Ghast Tears are solely used in brewing. They turn an Awkward Potion into a Potion of Regeneration, or a Water Bottle into a Mundane Potion.
