Neutral creeps

Neutral creeps are a type of creep not controlled by any player. They are aligned to neither of the teams, and offer an alternative source of gold and experience. Neutral creeps appear in small camps scattered in the jungle on both sides of the map. They come with different power levels and most of them have unique abilities. Roshan, who sits in his den at the river, is also considered a neutral creep.

Types
There are many different types of neutral creeps which spawn in small groups inside of camps within the jungle. These camps are categorised into small, medium, large and ancient creep camps.

Small camps
Small creeps are the weakest of the neutral creeps. They give little gold and experience, deal low damage and have low health, making them easy to kill for any hero at any time of the game. Usually, jungling heroes start farming these camps before other camps.

There are 6 different types of small camps, conisting of Kobolds, Hill Trolls, Vhouls, Ghosts and Harpies. The sixth camp type is a combination of kobolds and trolls. Besides the kobold camp which consists of 5 units, all small camps consist of 3 units.

Kobolds are the smallest creeps, but come in bigger groups. They are all melee and have no abilities besides one movement speed buffing aura on the biggest Kobold. Hill Trolls are ranged creeps, with one of the 3 having an active Heal ability which it spams whenever an ally is damaged, and a mana regen boosting aura. Vhouls are also ranged creeps and have all poisoned weapons, which afflicts damage over time. The ghost camp consist of 2 melee units and 1 ranged unit, which has a slowing attack. The Harpies are ranged creeps with effectively no ability. Although one of the Harpies has a very potent Chain Lightning, but it never uses it.

Medium camps
Medium creeps are also relatively weak camps, but stronger than the small creeps. They give a bit more gold and experience, deal low to moderate damage and have more health. Some of them can be dealt with early on, but some may be too strong.

There are 5 different types of medium camps, conisting of Centaurs, Wolves, Satyrs, Ogres and Golems. The number of units varies between 2 and 4 based on the camp.

The Centaurs are melee creeps, one of them being small and the other being big. The big centaur has a small area stun, which it only uses when enough enemies are within its range. The Wolves come in a pack of 3, all of them having Critical Strike. The big wolf also has an attack damage boosting aura, which makes this camp deal the most damage. The Satyr camp consists 2 small satyrs, which are comparable to the creeps in the small creep camp power-wise, are ranged, and have a Purge ability which they never use, and 2 medium Satyrs, which are melee and have a mana burning ability which they also never use. Ogres are melee creeps which come in a group of 3, from which one has the Ice Armor ability which it never uses. Golems come in pairs, but split each into 2 smaller golems on their death. They are melee and have a long ranged stun which they do not use.

1 Values include 4 Shard Golems.

Large camps
Large creeps are the strongest of the regular camps. Their gold and experience bounties per camp are on the same level as the bounty of a lane creep wave. They consist of strong creeps with strong abilities and are very difficult to deal with early on.

There are 5 different types of large camps, conisting of Centaurs, Satyrs, Hellbears, Wildwings and Trolls. Besides the Hellbear camp which consists of 2 units, all large camps consist of 3 units.

The Centaurs of the large camp are the same as the ones from the medium camp, except that the large camp contains two small centaurs and one big one, instead of one of each. The large Satyr is similar to the medium one. It contains the same small and medium Satyr, but one of each instead of two, and has a big Satyr, which is a strong melee creep with a strong long-ranged area nuke which it uses only if enough enemies are within range, and a strong health regen boosting aura. The Hellbears are strong creeps which come in pairs, both being melee. One of them has an area damage and slow ability which it only uses when enough enemies are within range, and an attack speed boosting aura. Wildwings are 3 melee creeps, two of them being small and relatively weak and one of them being big and able to summon a Tornado which deals area damage over time for a long duration. However it never uses that spell. Besides that, it also has an armor boosting aura. The trolls are ranged creeps, two of them being small and without abilities and the other being big, with two abilities. It can ensnare a target for a short duration, and temporarily bring the dead back to live, summoning 2 skeletons from a nearby corpse.

1 Values include 2 Skeleton Warriors.

Ancient camps
Ancient creeps are very powerful special creeps. Unlike the regular creeps, these creeps have as pecial unit type, the Ancient type, which makes them generally immune to many spells, such as dominating spells. They are impossible to deal with early on, and for some heroes even later into the game. They have very high health, deal high damage and have strong auras. They also have spell immunity, making it impossible to clear them with spells.

There are 3 different types of ancient camps, conisting of Dragons, Hides and Golems. All 3 camps consist of 3 units.

The Dragons are ranged creeps but have a short attack range. There are 3 dragons, 2 of them being small and relatively weak and one big dragon. The small dragons are the only ancient creeps without spell immunity. Ontop of being spell immune, the big dragon has 3 abilities: It is able to spit a fireball which engulfs a target area in flames, dealing damage over time, a passive splash attack which causes each of its attack to deal area damage and an armor boosting aura. The Dragon never uses its Fireball ability. The Hides are, similar to the dragons, ranged creeps with a short attack range. Also similar to the dragons, it conists of 2 smaller Rumblehides, and one bigger Thunderhide. But unlike the dragons, all 3 of them are spell immune. The Thunderhide also has 3 abilities: It can slam the ground, dealing area damage and slowing hit enemies, it can temporarily frenzy an ally, boosting its attack speed significantly and it has an aura which boosts attack damage and attack speed of nearby allies. The Thunderhide never uses the Slam ability, but does cast Frenzy on itself. The Golems are strong melee creeps. One of the three golems is stronger than the other 2, having much more health and a bit more damage. The big golem also has an aura which increases the healh capacity of nearby allies, making them the tankiest creeps of all, not only due to their high and boosted health, but also due to their high armor and spell immunity.

1 Ancient Granite Golem's increases nearby unit's maximum health by 15%.

Roshan
Roshan is a unique creep that spawns near the middle of the map. He also counts as an ancient creep and also has its own unique category. In addition to providing a large experience and gold bounty when killed, Roshan also drops the. The third time he is killed in a single game (and every time thereafter), a also drops from Roshan. Roshan's power increases as time passes.

Roshan has a high respawn timer when killed. He possesses 4 abilities from which one is active. His first ability is an area slam which damages and slows nearby enemies. The damage gets stronger as time passes. His second ability grants his attacks a chance to bash an enemy, stunning and dealing bonus damage. His third ability passively protects Roshan from a single-target spell every few seconds. His last ability grants Roshan permanent bonuses as time passes, increasing his health, armor and attack damage, while also grants him phased movement and also instantly kills any illusion which dares to attack Roshan.

Spawning
The first neutral creeps spawn 30 seconds after the first lane creeps spawn, which is at 00:30 game time. From there on, neutral creeps spawn on every minute mark (01:00, 02:00, 03:00, etc). A camp does not spawn neutral creeps when there are units within the spawn box of the camp. The spawn box areas can be seen by holding down the ALT key (if the option is enabled). However, some units are ignored and cannot block a creep camp.

Neutral creeps spawn every minute-mark after the first creep spawn, with the first spawn being at 00:30. Aggravated creeps follow units out of their camp for up to 7 seconds, and then start returning to the camp area. This delay in the return can be used for Creep Pulling, which pulls neutral creeps into contact with Lane creeps, and Creep Stacking, which causes multiple camps of creeps to spawn in one area.

Neutral creeps do not spawn if there is a unit (excluding lane creeps) within their camp. This includes heroes, player-controlled units, neutral creeps, certain projectiles such as, and wards. Neutral camps do not spawn the same set of creeps twice in a row. Lane creeps do not block spawning.

Each team's jungle includes one small creep camp, two medium creep camps, and three large creep camps. On average, a run through the jungle (not including ancients) yields 533 gold and 893 experience.

On average, completing both ancient camps yields 528 gold and 710 experience.
