Guardian of Yendor

*'This is it, this is the legendary, dreaded **Guardian of Yendor'*****. The instant you dare to pick up the famous Amulet of Yendor, its guardian will attack and chase you wherever you go.**

HINT: *'There are almost as many stories about the Guardian of Yendor, as there are about the Amulet of Yendor itself. Most of the stories about the guardian also report that the legendary amulet is still safely tucked away in this dungeon. Good thing they let you know where to find it, so can take it and go home. Right? Right! What could possibly go wrong?'*

The Guardian of Yendor will appear soon after acquiring the Amulet of Yendor from the dragon guarding it. But only after leaving the floor where the amulet is acquired. A message will indicate that the guardian has arrived. The Guardian will chase the player back up through the entire dungeon up to the top level. It is not required and not recommended to kill the guardian.

The Guardian of Yendor is the most powerful enemy in the game, and has the following attributes:

* The guardian always carries a +3 great sword with a random strong positive prefix (e.g. lightning, vampiric, frost) and a +3 short sword of mastery. If you can kill him, the great sword (both swords?) has infinite magic charge. A good enchantment (e.g. vampiric) makes it easy to farm respawning enemies for stupid amounts of gold or other valuables (e.g. dragon scales from wyrms, or creep skulls from creeps). However, the infinite charge is lost if the sword gets corroded; hold on to a protect scroll if you plan on farming creeps.
* The guardian has 1000 health.
* He floats.
* He can't be disarmed.
* He Is immune to most arrows fired from a bow. Special attacks from magic bows (e.g. lightning, magic missiles) still work.
* Mirrors melee damage; hitting the guardian in melee causes equal damage to the player, plus weapon effects.
* The guardian frequently teleports near you, and will hit you with a teleport butt-rape attack (where, like many other teleporters, he instantly automatically hits you with the poke attack from his sword). This can be instant, unvoidable game over if the Guardian has a nasty weapon (e.g. a sword of slaying).
* The guardian can shoot lightning that often bounces from walls, and stuns the target. Can be another instant kill if he follows up with a teleport stab after stunning you with lightning.
* The guardian can NOT see an invisible player. He will still teleport near the player however, so invisibility isn't foolproof. Run before you invisibility expires. Also, it is worth it to switch to a non-poke weapon (e.g. axe, mace, morning star) so you don't accidentally poke the guardian while he is teleporting around, which would dispel your invisibility.
* The guardian seem to be an unholy creature, thus, holy water flask does 20 damage to him and light scroll damages him and stunts him.

The safest way to fight the guardian is with magic staves. The guardian is vunerable to most damage spells. A fireball staff can hit twice per shot (direct hit and then another hit from the shockwave), for up to 48 damage per hit for a +5 staff. A high-level triple-missile staff also works well, though doesn't do nearly as much damage as the fireball staff. One or more of these and several scrolls of recharge is enough for victory. The guardian can't dive in water, and can't attack you if you are under water. Also, your own explosion spells won't hit you under water. Thus, fighting him near deep water is a significant advantage. You can surface, shoot spells at him, and then dive for cover. A helm of the deep makes this tactic much easier. Even the fiery doom stave can be shot while standing on land, and then you can dive, and the staff will continue shooting the other 9 shots while you are safely under water.

Other than gaining bragging rights and the nice swords after defeating the Guardian, the merchant at the end of the game will sell one additional painting about the victory over the Guardian, while also expressing disbelief that you could kill him.
