|Release date||11 April 2017 (Update)|
|Growth time||900 minutes|
|Examine||Everyone starts out somewhere. And now you have one follower!|
A prime colossus has three stages of growth. It will take approximately 15 hours to reach the adolescent stage and an additional 25 hours to reach the adult stage, though this can be sped up by interacting with the pet. Stages can be skipped by using a Growth Surge on the pet, e.g. baby to adolescent or adolescent to adult.
Like all pets and summoning familiars, it cannot enter or use its abilities in certain areas.
Legendary pets have several unique abilities, described below. Pets in the baby stage can have one active ability, adolescent pets can have two, and adult pets can have three. Abilities can be switched out at any time unless that ability is on cooldown. Active abilites are switched via the pet interface by clicking on the "Abilities" button at the bottom right corner.
Life Saver, Slayer Finisher, Repair Item and Fertiliser are not available for Ironman accounts.
|Forage||The pet can randomly forage items when they are summoned. This can also be triggered actively. The foraged item is always one of the following:|
|Banking||The pet is able to take an item to your bank; they can take one item every 10 minutes, and a stack of noted items are banked all at once. The pet's ability to bank does not work beyond level 1 Wilderness. If one just crosses the Wilderness wall (and the Wilderness level display does not actually appear; thus can be considered "Wilderness level 0") and does not walk north, then the pet's banking ability still can be used.|
|Scavenge|| The pet is able to scavenge dropped items from the moment it is obtained. To access the scavenge feature, 'Interact' with the pet and select 'Convenience', then select 'Scavenge'. When scavenge is selected, a menu interface will appear; the pet will automatically collect charms, but is able to pick up other items too. You can make the pet scavenge: Gold, Runes & Talismans, Herbs & Seeds, Weapons, Armour, Metal Bars & Ore, Bones & Ashes, Raw & Cooked food and Miscellaneous.
The pet will only pick up one item from a slain enemy; if an enemy drops two or more items, the pet will only pick up one. The pet will not always pick up items after a kill. There is a chance that the item picked up by the pet will appear in your bank rather than being in your inventory. This ability has a cooldown of 10 seconds.
To deactivate scavenge, 'interact' with your pet, select 'convenience' and select 'Heel'.
|Life Saver||Your pet will save you from death, as per a ring of life. This does not work in PvP areas and has a two-hour cooldown (logged-in time).|
|Slayer Finisher||Your pet will automatically finish off Slayer monsters that usually require an item, saving you an inventory slot.|
|Item Repair||Once per hour, you can use a repairable degrading item on your pet to repair it immediately. This works – and costs – the same as using the POH armour stand.|
|Beast of Burden||Using a Beast of Burden familiar pouch on the pet allows it to act as a version of that familiar with 10,600 life points and the same time limit. Using multiple pouches on the pet lets you extend the time for up to two hours. Unlike most Beasts of Burden, legendary pets do not use Summoning points. This ability cannot be used in the Wilderness.|
|High Level Alchemy||Once per 10 minutes, use an item on your pet to convert it to coins, as per the High Alchemy spell. This requires 55 Magic, but does not need runes and gives no experience.|
|Fertiliser||Every hour (of logged in time), the pet can be interacted to spawn pet droppings. It can be picked up for six buckets of compost or supercompost if the player is on a member's world. It also has a 1 in 10,000 chance of spawning Mod Daze's homework or Mod Dolan's rubber duck.|
