Potion of Holy Water

Potion of Holy Water
The Potion of Holy Water is a bright yellow potion that inflicts the Angelic effect. It will heal entities similarly to the vanilla Potion of Regeneration, but will also cause huge damage to undead creatures. If it is thrown on an infected zombie villager, they will immediately heal and will be restored to their former state.

The Potion of Holy Water is brewed from the vanilla Potion of Regeneration and Blessed Powder. If the base potion is brewed with glowstone dust, the Potion of Holy Water II (which does double the damage/heal) is created. Similarly, if the Potion of Holy Water II is brewed with a Plagued/Pure Tear (a Plagued Tear, in this case), a Potion of Holy Water III (four times the damage) is created.

If the base potion is brewed with redstone, a Potion of Holy Water with double duration is created. If this doubled potion is brewed with a Pure Tear, the duration is again doubled, resulting in quadruple duration.
