The OSRS Holy Grail is the subject of many myths and legends. Traditional belief holds that the Holy Grail is the cup Jesus Christ drank from at His Last Supper, and Joseph of Arimathea used to draw Jesus' blood during the time of his death. Everyone can be a part of this mythical tale in OSRS.
The OSRS Holy Grail quest is part of the Camelot quest series where King Arthur is trying to find the OSRS Holy Grail. Also, you are being taken by King Arthur on a quest.
The requirements and items required for OSRS Holy Grail Quest
Before you can start this quest, you must to complete Merlin's crystal quest. After that, you will encounter in the quest some levels 120 Black Knight Titan, so you need to take them down and you must have at least 20 Attack skill.
For the things you only need one, and that's Excalibur. I would also suggest bringing along Teleport to Camelot Teleport to Falador, Antipoison and some food items.
King Arthur Arthur
To begin the OSRS Holy Grail quest you have to talk to King Arthur to tell you about the holy the grail. After that talk to Merlin who is on the first floor of Camelot Castle.
He will be found once you reach the south-east side of the castle, by climbing up the steps. He will tell that you should talk to one of the people on a "holy island" and also Sir Galahad who lives somewhere west of McGrubor's Wood.
The Holy Island of Entrana
Now, go to Port Sarim and speak to the monks who are on the pier about sailing to Entrana. Monks won't let you to enter Entrana when you are carrying weapons or armour. There is a bank deposit box right next to the monks, in case you forget to bank your gear.
Speak to the priest high up, and he'll inform you that the OSRS Holy Grail isn't accessible. A strange old crone will then appear and tell you that Fisher King is in trouble. You'll need to locate six stone heads across the globe, and then go to where they point when you have a magic whistle.
You can teleport to the Ranging Guild using a combat bracelet. Go to Galahad in the west of the house McGrubor’s Wood. Tell him you're looking for an item that comes from the Fisher Realm, and he will give you a holy table napkin.
Then, go up the stairs of Draynor Manor into the southern room, which is occupied by Professor Oddenstein. The table napkin that is holy must be present to see the whistle respawn. You can then take two magic whistles.
The Black Knight Titan
The fastest way to Brimhaven is to use the scroll of redirection feature on an teleporter to house tablet and then redirecting it to Brimhaven. Charter ships that go to Brimhaven can be taken from Port Sarim or the Catherby docks for 1,600gp each.
It is also possible to use the Fishing Trawler minigame to teleport and easily charter a ship to Brimhaven for 1,600gp. Once you arrive in Brimhaven then head to the north-west of the town, which is where the gold mine is.
You'll be teleported to the Fisher King's Realm if you find a guard tower north from the gold rocks. Bring Antipoison with you in case you're below Combat Level 41. There are level 20 poisonous scorpions.
To speak with the Fisher King, you will require crossing the bridge. The Black Knight Titan is there and will not let you go without fighting. The titan has to be defeated with the Excalibur blade only, although you may make use of other weapons to bring down his health.
Although the titan isn't very prone to attack styles, he is resistive to Ranged or Magical attacks. This is the reason why Melee is recommended. Use the hit-and-run method to kill him however, make sure the final blow comes from the Excalibur.
After you've killed the titan After you've killed the titan, cross the bridge, and continue south along the river until you come across the Fisherman. Speak to him and ask what you need to do to enter the castle. You'll need to ring the bell.
You will find a grail bell at the castle entrance. When the dialogue has ended then ring the bell to enter the castle. When you are inside, take the magical whistle off the floor.
Talk to the Fisher King by climbing up the steps. Choose option 3. He is extremely sick and would like to see his son again. Percival is the son of a knight at the table. If you're wearing the runes, blow your whistle a second time for teleportation.
The Final part of The Holy Grail Quest
Talk with King Arthur. He will tell you that Percival isn't within his control. King Arthur will present you with an enchanted gold feather which points to the gold boots Percival was wearing. It is possible to blow on the feather to direct you towards Goblin Village. Teleport to Falador and then turn north.
When you reach the Goblin Village go into the house on the east side, unzip the sacks and there's Sir Percival. Inform him that your father would like to meet you. Percival does not know how to reach the castle so the last whistle from your collection will be given automatically to him when the conversation ends.
Head back to the Fisher King's Realm like before. You can teleport there using fairy rings (BJR). Visit the spot in which the Fisher King was and then enter the castle.
Go through the south-eastern entrance and climb the stairs up to the tower. Then, you will be able to find the Holy Grail by climbing up the ladder. Following that, head back to King Arthur in Camelot and speak to him.
