Nechryael

Nechryael are level 115 demons that require level 80 Slayer to kill. They are found on the top floor of the Slayer Tower in Morytania and in the Chaos Tunnels. They give 105 Slayer experience when killed and do not require any special equipment to kill. They are also currently the only monster to drop Rune boots. Their drops are very similar to the drops of greater demons.

Strategy
As Nechryael are demons, the magical abilities of Silverlight, Darklight, and Holy water affect them.

When engaged in melee combat, a Nechryael may randomly summon up to two level 46 Death spawns to assist them. These will attack the player even if the player is standing in a single combat zone and is already under attack. Players being attacked by death spawn will not automatically attack them even if auto-retaliate is switched on.

Death spawn can be avoided by running a fair distance away, such as to the opposite end of the room. After a few seconds, the Death spawn loses interest and stops trying to attack the player. This is easiest to do in the Slayer Tower, with its large rooms but is also fairly easy to do in the Chaos Tunnels. This tactic works best after the summoning Nechryael is killed, or otherwise a Death spawn that disappears will soon be replaced by a newly summoned one.

Death spawn drop nothing but ashes when killed. Most players with a high defence choose to ignore them completely because they inflict so little damage that they are not worth the time to avoid. However, Death spawns have a magic based attack so they will be able to hit through melee prayer. This could be an issue if you choose to use Dharok's armour while killing Nechryaels.

Using a Guthan's set against Nechryael is extremely effective. Also, one could use Guthan's/Saradomin Godsword special/other healing method on the death spawn because of their low defence compared to nechryael.

Additionally, bursting/barraging/chinning Nechryael are a great source of crimson charms for players (in the Chaos tunnels) because the rune drops can offset some of the cost of the runes or chinchompas.

For those who wish to mage/range Nechryael in the Slayer Tower, there is a table in the northwest corner of the room that can be effectively used as a safespot. Another good strategy is to stand behind a Death spawn so the Nechryael will get trapped behind it (as seen in the screenshot).

Trivia

 * One of Nechryael's attack is using its head, which appears to be a bite, somewhat similar to how Vampires occasionally attack, though the Nechryael could simply be headbutting the player.
 * A death spawn apparently remembers which Nechryael called it forth. Once its Nechryael is killed, it will disappear after a few moments, even if it is still attacking you.
 * If you kill a death spawn's Nechryeal or run away from the death spawn, it will give up trying to attack you at about the same time (if not precisely the same time) that a familiar will teleport to get close to you.
 * Nechryael are a great monster for collecting seeds, as they drop high level seeds very often, especially Toadflax seeds.
 * Although auto-retaliate does not work against Death spawns, their attack will still interrupt teleporting with a 2-click teleport like a Ring of duelling (unless you equip the item and then teleport through the Equipment screen).
 * You can log out while a Death spawn attacks you.
 * The Nechryael has an odd resemblance to Ankous, though they have very little in common.
 * The Home Teleport spell is not interrupted by Death spawns.
 * Despite having an undead appearance, Nechryael's are not weak to the Salve Amulet.
 * Many players feel that it is unfair to have multiple monsters attacking you in a single-way combat zone, as this is what happens in the slayer tower, but in most regards the Death spawns do not count as monsters.
