Holy water

Holy water is a powerful Ranged weapon that is used just like throwing knives and darts; however, it is only effective against demons. Holy water is nontradeable and has a +6 Ranged attack bonus when wielded. It is very effective against most types of demon (except Tormented Demons) and leaves behind smashed glass when used.

The making of Holy water is learned during the Legends Quest. It cannot be made by players who have not made sufficient progress into the quest. A blessed gold bowl, blessed by Gujuo, must be used to transfer the pure sparkling clear water found within the Kharazi pool into enchanted vials to make Holy water. Once the water is gathered into the bowl via a cut reed, it will need to be poured into enchanted vials which, when filled, are stackable. One bowl will fill ten enchanted vials.

The most effective way to make Holy water in bulk is to make 26 or 27 blessed gold bowls (takes a while), fill them, and use Karamja gloves 3 to teleport to Shilo Village. The most effective way to make the enchanted vials is to use restore potions along with the sulphur spring spa in Oo'glog with its nearby bank. Alternately use the bank at the Ourania Altar with the prayer altar directly above the bank (use cheap runes to bank, like body runes). Using these methods can cut cost and reduce time in making Holy water, potentially making up to 1,000 Holy water per hour (estimated).

Trivia

 * If worn along with the Mourner clothes you would look like some mourners from East Ardougne as they seem to carry vials of blue liquid.
