The Obelisk of Water is located on the Water Obelisk Island off the shore of Catherby. It can be reached by climbing the ladder near the black dragons in Taverley dungeon. Players may grapple from the island to Catherby although they can't go the other way.
The obelisk is used to charge an unpowered orb into a water orb using the Charge Water Orb spell (with level 56 Magic, 3 cosmic runes and 30 water runes). A staff of water, or another staff that gives free water runes, is recommended to save on runes. A water orb is needed to craft a water battlestaff. Water orbs are also used in Summoning when making hydra pouches.
An effective route for charging multiple orbs is to bank in Catherby, grapple over White Wolf Mountain and head south to Taverley dungeon. Upon navigating the dungeon reaching the obelisk, the player can then charge, bank and repeat as required. This method requires a mithril grapple and any crossbow of mithril or higher quality, 39 Ranged, 36 Agility and 35 Strength. Level 70 or 80 Agility is very helpful for navigating Taverley dungeon more quickly.
An alternative route to grappling the mountain is to lodestone teleport to Taverley, run south to dungeon and then continue as above.
You can also build a hidey-hole from the water obelisk island, you don't have to bring further materials from then on. Level 49 Construction, 4 teak planks, a mithril crossbow and a mithril grapple along with a hammer and saw are needed.
