Ghast Tear

Ghast Tears are items dropped by Ghasts when they are killed. Ghast tears are relatively rare, as not many Ghasts will drop tears. Ghasts are very difficult to defeat successfully, and normally the tear drops into lava and is lost.

Use
Ghast Tears are items used in brewing. They will turn an awkward potion into a potion of regeneration, or a water bottle into a mundane potion.

History
In 1.9 pre-releases 2-3 Ghast Tears were used to make Potions of Healing, but since 1.9 pre-release 4 they have been used in Potions of Regeneration. This was due to the sheer amount of difficulty in obtaining them. Glistering Melons were added to create Potions of Healing.
