Dreadnip

A Dreadnip is a stackable item that will spawn a level 565 Dreadnip.

It is a reward from the Dominion Tower - to obtain 100 Dreadnips, one must kill 450 bosses in the Dominion Tower and spectate one other player's match. Thereafter, 100 Dreadnips can be obtained every 5 activities completed within the Tower.

Dreadnips cannot be used in the Dominion Tower, against players, against treasure trail foes or against certain high level or boss monsters. It is thought that the monsters the Dreadnip can't attack are quest monsters, as it can attack any regular boss from the King Black Dragon to Nex. They are not considered familiars and therefore can be used with another summoning familiar or in the TzHaar Fight Cave. It can, however, attack other players' summoning familiars. Monsters do not retaliate against the Dreadnip and players cannot attack it. Players' summoning familiars are also unable to attack the Dreadnip as it yields the message "You can't attack this NPC."

Only one can be spawned at a time, and it only attacks one target. To spawn a Dreadnip to attack an enemy, the enemy must be attacking you, OR you must be attacking it. If you exit combat or stray too far from the Dreadnip, it will disappear. The Dreadnip also naturally disappears after around 30 seconds (5 combat actions), if the target dies, or if it loses sight of the player. Another can be spawned immediately after the previous one disappears.

The Dreadnip hits for up to 550 typeless damage (no icon indicating its damage type). As such, it is able to damage enemies that are otherwise invincible (e.g. A shielded Frost dragon). It can also damage enemies that you do not have the sufficient Slayer level to kill. It is unknown if this is intended. It only attacks at melee range. It attacks more slowly than a Dark bow on Accurate, having a 6.0 second delay between attacks and thus an attack speed of 0. The Dreadnip can hold the target in place for 20 seconds (similar to Entangle) and poison it (starting from 108). Each subsequent poison splash is two less than the previous.

If it does not attack, make sure it has a clear path to the targeted monster (it cannot walk through players). If Monster Examine is cast on a Dreadnip, it will only say, "You can't find out their stats."

A dreadnip also totally ignores the rules of multicombat. If the player attacks a monster in a singleway combat zone then the Dreadnip will be able to attack the same monster.

You receive experience in the last melee skill you dealt damage in for the damage inflicted by the Dreadnip.

Monsters that the Dreadnip cannot target
If you attempt to have a dreadnip attack one of these, it would yield the message "The dreadnip couldn't attack so it left."
 * Barrows brothers
 * Saradomin wizards while doing hard coordinate clues
 * Double agents while doing hard emote clues

Trivia

 * Even though the examine text says, "Don't look it in the eyes!", the dreadnip only has one eye.
 * It counts as a "non-combat item" and cannot be taken into Soul Wars.
 * Dreadnips can damage targets requiring special equipments to fight, such as the Wild Jade Vine or Vampyres, and may inflict poison damage against them which is otherwise impossible.
 * Dreadnips can attack Kree'arra, who normally requires Ranged or Mage attacks to be damaged.
 * The best way to deploy Dreadnips is click "deploy", click its picture, click the enemy, wait until it is deployed, then re-attack the enemy.
 * Deployment typically takes 0.6 seconds, and doing something (such as clicking to attack the enemy) during that 0.6 seconds will interrupt and cancel deployment.
 * Until a recent update, players were allowed to target dreadnips at monsters that they were not engaged in combat with as long as the player was in combat, even in a non mulit-combat area. Attempting to do so now will yield a message saying that the targeted monster must first either attack or be attacked.
 * The dreadnip's max hit is severely reduced when used against monsters in the Polypore Dungeon, which are all highly resistant to melee and ranged.
