Snape grass

Snape grass is a members-only item used in the making of prayer potions and fishing potions. It can be used in a hangover cure, which is needed in the Plague City quest and the Mogres miniquest.

Three clumps spawn at the Hobgoblin Peninsula south-west of the Crafting Guild, and twenty-seven spawn around Waterbirth Island. Three of those spawns require the use of Telekinetic Grab. Chaos Druids and Waterfiends drop them, and players can also loot it from implings.

Collecting and money making
A player can make a great deal of money by collecting and selling snape grass through the Grand Exchange. Snape grass is coins each; for comparison, pure essence is  coins.

Players who have completed the The Fremennik Trials can travel to Waterbirth Island. They can collect 28 snape grass and can either walk or teleport to the nearest bank. If they haven't completed The Fremennik Trials, players can go to Waterbirth Island for the cost of 1,000 coins. If a player has the Fremennik Sea Boots 1, they can then use Peer the Seer to deposit their items. However, this only allows players to collect 27 snape grass (except on the first trip), and they must access a bank to withdraw the coins to go to Waterbirth Island. However, players can work around this by dropping their money beforehand; but if a player gets a random event and is teleported away, they may lose their coins, so this is not recommended. If you have completed The Fremennik Trials, you can go to Waterbirth for free.

Players can repeat this process indefinitely, but it would be a good idea to wear weight-reducing items, such as boots of lightness and a spotted cape, to help their energy last longer. Players who have completed the quest can also make money from snape grass by using the banks in Neitiznot, Jatizso, and Miscellania if they have done the required quests to access these areas.

Players with a POH (player-owned house) can have their house moved to Rellekka (via an estate agent), ride the boat to the snape grass, then teleport to a bank with teleporting jewellery.

Another good way for money making with snape grass is by using Lunar Magicks spell Waterbirth Teleport. While equipped with a Mystic mud staff or Mud battlestaff, a seal of passage, as much weight reduction equipment as possible, and a large quantity of law runes and astral runes, teleport to Waterbirth Island, collect snape grass from anywhere on the island. Then teleport to Catherby using the Catherby Teleport spell,(as this is the closest Lunar teleport to a bank) or a Ring of Duelling teleport to Castle Wars which will teleport you right beside a bank. Using this method will allow you to collect 26 snape grass for each run as you will have the law and astral runes, or 28 snape grass for each run with RODs. If you have a Magic level of 73 or higher and are using a mud battlestaff or mystic mud staff, it is suggested you use Tele Group Waterbirth and Tele Group Moonclan as you will use the same amount of runes but will gain more Magic experience.

After 1 hour of consecutive test runs, using a spirit terrorbird, and rings of duelling, this method made just over 520k an hour if done fast enough. Using other familiars that holds items won't help much, as they do not restore run energy like the spirit terrorbird does (the bull ant also does this, but it holds fewer items).

Trivia

 * Getting this from waterbirth island is a popular way for new players to get money. That's one of the reasons the price went down in the grand exchange.
 * Some people think that snape grass is a reference to Severus Snape (the potions master in the 'Harry Potter' series).
