OSRS Boss Pets: All 54 Pets and Their Drop Rates

OSRS Boss Pets: The Short Answer

The OSRS Wiki lists 54 boss pets, almost all of them tertiary drops rolled on top of your normal loot. Most sit between 1/2,000 and 1/5,000. The shortest per-kill odds are Skotos from Skotizo at 1/65, and the longest is Tiny tempor from Tempoross at 1/8,000.

When a pet drops you see the message "You have a funny feeling like you're being followed." If you already have a follower out, it goes to your inventory instead. Pets can be banked, and a menagerie with the highest-level pet house holds up to 71.

Every Boss Pet and Its Drop Rate

Rates are per kill unless the table says otherwise. Raid pets roll on the raid completion, and the Phoenix and Tiny tempor roll when you collect from the Wintertodt reward cart or the Tempoross reward pool.

Pets You Can Gamble For

Four pets can be gambled for as well as dropped. Three of them cost the item you earned: TzRek-Jad takes a fire cape, Jal-Nib-Rek an infernal cape and Smol Heredit a Dizana's quiver, and each sacrifice makes the same roll as a kill (1/200, 1/100 and 1/200). The Pet Penance Queen comes from the Barbarian Assault gamble at 1/1,000. You cannot gamble for a pet you already own in your bank, inventory, menagerie or as a follower.

Each Jal-Nib-Rek gamble uses up a whole infernal cape. If you have not earned your first one yet, the infernal cape service is done by hand.

How to Raise Your Pet Chance

• Slayer tasks: TzRek-Jad goes from 1/200 to 1/100 per kill on task, and Jal-Nib-Rek from 1/100 to 1/75.
• Give up the loot: sacrificing Royal Titans loot or destroying Araxxor instead of harvesting it doubles the pet chance to 1/1,500.
• Delve deeper: the Doom of Mokhaiotl pet improves from 1/1,000 at delve level 6 to 1/250 at level 9 and beyond.
• Smaller teams: Little Nightmare is 1/800 solo and gets worse with every extra player, down to 1/4,000 at five or more.
• Contracts: a Contract of Familiar Acquisition makes Yami 1/100.
• Pick the right version: Corrupted Gauntlet (1/800) beats the normal Gauntlet (1/2,000), and Callisto, Venenatis and Vet'ion (1/1,500) beat Artio, Spindel and Calvar'ion (1/2,800).
• Abyssal Sire: each unsired used on the Font of Consumption has a 5/128 chance at the Abyssal orphan.
• Theatre of Blood: Lil' Zik is 1/650 at best in Normal Mode and falls toward 1/6,500 with poor personal performance, while Hard Mode starts at 1/500.

Pets Are a Volume Game

Every roll is independent, so nobody is ever due a pet. At a 1/5,000 rate, about 37% of players still have no pet after 5,000 kills and about 14% after 10,000. Pick a boss you would farm anyway for its drops, raise your kills per hour and let the pet turn up when it does.

Boss Guide Index: Access Requirements

The table below covers the 97 bosses we have guides for, sorted by group and difficulty, with the requirement you need before your first kill. Not every entry has its own pet (raid sub-bosses share the raid's pet, for example), but every pet above comes from one of these fights or its raid.

FAQ

What is the rarest boss pet in OSRS?

By listed rate, Tiny tempor at 1/8,000 from the Tempoross reward pool. Among combat bosses the rarest are the 1/5,000 pets: the four God Wars Dungeon generals, the three Dagannoth Kings and the Corporeal Beast's pet dark core. The Phoenix from Wintertodt is also 1/5,000.

What is the easiest boss pet to get?

Skotos at 1/65 per Skotizo kill has the shortest per-kill odds. The Olmlet's 1/53 looks better, but it only rolls for the player who receives a unique from Chambers of Xeric.

How many boss pets are there?

54 on the wiki's boss pet list as of October 2026, counting a pet once even when two bosses share it (Callisto and Artio both give the Callisto cub). The Pet Penance Queen from Barbarian Assault is listed separately.

Does anything increase pet chance?

At some bosses, yes: Slayer tasks at the Fight Caves and Inferno, giving up loot at the Royal Titans and Araxxor, deeper Doom of Mokhaiotl delves, smaller Nightmare teams and the Yama contract. Everywhere else, kills per hour is the only lever you control.

Bottom Line

54 boss pets, with per-kill rates from 1/65 to 1/8,000 and a handful of bosses where you can push the odds in your favour.

Beef from Brutus (the Cow Boss) at 1/1,000 and Skotos at 1/65 are realistic early pets. The 1/5,000 group is a long-term side effect of farming the God Wars Dungeon, the Dagannoth Kings or the Corporeal Beast. Each row in the boss index links to its own guide for mechanics and drops.
