Ghostly warrior

The Ghostly warrior was released 29 July 2008, with the quest Spirit of Summer, that is required to access them. They have fairly low defence, so may get very popular for training. These monsters are a variation of ghosts, so can be used on such slayer task. Also, as undead they are affected by the Salve amulet and Crumble Undead spell. To fight them, it's recommended to bring alchemy runes, because of the common steel armour drops. They are also good droppers of cosmic and mind runes. You need Jennica's ring to get to them, but it is recommended to switch to and wear a Ring of Wealth once there.

Habitat(s)
To access them, you must have completed the Spirit of Summer quest. In the Axe Hut, deep Wilderness, wear Jennica's ring, and operate it when standing right next to the portal you see. You will be taken to the Spirit Realm, where, in place of the Magic axes, there will now be Ghostly warriors (who don't wield an axe). To leave, just step into the portal and operate the ring again, or run away from the building. The best way to access the portal is using Ardougne's lever to Wilderness. They are aggressive to all levels, but with time become tolerant.

As the Spirit Realm is classed as outside the wilderness, all methods of teleportation can be used. However, entering the Spirit Realm (via the portal) is counted as a teleport, so bringing a Forinthry brace to counter a Revenant's teleblock is recommended.

Note: You will also need to bring a lock-pick for the doors into the spirit axe hut.

Trivia

 * The examine of the warrior, "A spectral warrior with no axe", this implies that their non-spiritual counterparts are Magic axes.
 * Soon after the release of Spirit of Summer, it was possible to enter the hut without a lockpick; this has since been changed by Jagex.
