Enhanced Excalibur

The Enhanced excalibur is an upgraded version of Excalibur that may be obtained upon completion of the Seers' Village Diary. The Lady of the Lake will enhance Excalibur after completing the hard portion of the Seers' Village Diary and wearing the Seers' headband 3 (not necessary if obtaining a replacement). Enhanced Excalibur's stats are comparable to that of a rune longsword, and it has an enhanced special attack that, in addition to a 15% boost in defence, heals the player 40 life points every 2 seconds for 10 seconds for a total of 200 life points. This increases up to 400 life points over 20 seconds for players who have finished the elite tasks for the Seers' Village Diary. This uses up 100% of the special attack bar.

NOTE: If you happen to log out during the special's effect, the special will NOT continue healing you after you log in again. However, the effect will continue if you switch weapons.

Like poison damage, the effect will stop when a player is banking and continue immediately when the bank is closed.

Once enhanced, it can no longer be mounted onto the wall of a player's Quest Hall, however when reclaming the excalibur from the Lady of the Lake it will give you the option to get the original one instead.

If lost, you can receive a new one from the Lady of the Lake. It costs 500gp to get a replacement.

Uses for the special attack

 * Saving many inventory spaces during quests by not having to bring as much food or a familiar.
 * Having in inventory as a staple special weapon when you have a chaotic weapon.
 * Healing at the bank when lifepoints are low.
 * Keeping in inventory for those times when you can't think of a good special weapon to bring.
 * Healing when training Thieving or Agility.
 * Replacement for Saradomin Godsword, but one that doesn't unequip your shield or protect over your other items.
 * Healing when training Ranged or Magic as many ranged and magic weapons do not use Special Attack energy (E.g. Aviansies/Kree'arra).
 * Replacement for waterskins or enchanted water tiara during desert travels.
 * Defence boost in combat activities like Soul Wars or Barbarian Assault.
 * Romping around RuneScape without having to bring multiple food or bunyip backup.
 * Healing during the Fight Caves while giving a Defence bonus.
 * Healing during trips to the Abyss.
 * Healing when doing Phoenix Lair.
 * Healing when doing long trips at Barrows.
 * Camping at certain areas without having to bank for food.
 * Replacement for defence potions and food during Slayer tasks or when training combat.
 * Healing while fighting Waterfiends, which usually negates the need for a healing familiar or food with high Defence and Magic levels.
 * While mining or fishing at the Living Rock Caverns with good armour there is little need for a healing familiar or food.

Trivia

 * After the Game Engine update of 2 September 2009, the special attack did not activate until you attacked something. This was fixed later the same day.
 * The special attack can be used while resting - the player will stand to perform the special attack emote, but resume sitting afterward.
 * Some players have reported a glitch where the Enhanced excalibur will perform its special attack randomly. The sword would remain within their inventory and will perform the special attack, but without the player having to click on Special Attack. This sword does not have a right-click option in the inventory menu to activate its special(fixed in September 2010 with a hidden update).
 * Multiple Enhanced Excaliburs may be obtained. If a player possesses multiple Excaliburs and takes them to the Lady of the Lake to be enhanced after completion of Seers' Diary 3, they will all be upgraded. Similarly, a player may buy a new Excalibur if he/she loses destroys it and choose between having the original or enhanced version (note that the player must have no enhanced version to buy more). By choosing originals, dropping them to buy the desired amount and picking them all up, a player can talk to the Lady of the Lake and have all Excaliburs enhanced in one go.
 * Its special attack is similar to the saradomin godsword as they both heal the player. In non-combat situations where you still need more LP, the Enchanted excalibur is considered to have the best special attack as it activates directly by clicking the bar.
 * Many players wield this in PvP whilst gaining Earning potential to decrease the chances of being targeted as it looks exceedingly similar to Vesta's longsword (although the colour of the hilt differs).
 * According to the actual legend, this sword could only be used to its full potiential when wielded by Uther (King Arthur's father), and can defeat any opponent. It was also enchanted by a dragon rather than the Lady of the Lake.
