Excalibur

Excalibur is a member's only quest weapon, that was once and still wielded by the legendary King Arthur. To wield this weapon the player needs at least 20 Attack. To receive Excalibur the player must complete the Merlin's Crystal quest to a certain point. It can be displayed in a player-owned house with 38 Construction. This weapon cannot be made using the Smithing skill.

Excalibur has a special attack called Sanctuary. This raises the user's defense while the they shout "For Camelot!"

Excalibur is used again in the Holy Grail quest, and can be recovered if lost by paying 500 gp to the Lady of the Lake south of Taverley.

Excalibur has the same bonuses as an Adamant longsword, except Strength, and with the addition of a special attack.
