Roshan

Roshan, sometimes also referred to as Roshan the Immortal, is the most powerful neutral creep in Dota 2. It is the first unit which spawns, right as the match is loaded and is the only NPC which scales over time. During the early to mid game, he easily outmatches every hero in one vs one combat. Very few heroes can take him on alone during the mid game. Even in the late game, lots of heroes struggle fighting him one on one, since Roshan grows stronger as time passes. Roshan is not a creep which can just be farmed like the other neutral creep camps, fighting him is an important team decision, as it needs the correct timing and approach since it can decide the future of the match. Usually, it is fought as a team when it is safe to do so, meaning when the enemy team does not display a threat at the moment (for example after a successful team fight).

Roshan Pit
Roshan can be found inside his pit, which is located to the right of the bottom rune spawn point. The entry is connected with the river, and faces west. The pit has about 1000 range length and 250-300 range width. Roshan always stays at the end of the pit when not attacking and only attacks if enemy units come within 150 range of him, or damage him from within 1800 range. Roshan cannot be attacked from outside the pit; however, he can always attack.

Vision inside the pit
The only way to gain vision over the pit is to enter it. Units with ground vision (this includes wards and any spell) from outside cannot see into the pit, no matter how far their sight range goes or if they are on an elevated area like the ward spots. s and s cannot be placed inside the pit at all. However, units with flying, or unobstructed vision can see inside the pit from the outside. So the only way to gain vision inside the pit is to have an owned unit with ground vision in there (e.g. the hero itself, summoned units or wards such as, or ), cast a ground vision providing spell like  or  inside there, have a unit with flying vision (e.g.  with  or the hawks from ) near the pit, or cast a flying vision providing spell like  or  near the pit. Scan does not react on the presence of heroes inside the Roshan Pit.

Roshan's death
When Roshan is slain, a global sound resembling its Roshan_Death.wav screaming, along with a special piece of Roshan_Death_Default_Music.mp3 music and an announcement from the announcer are played for all 10 players. Along with that, a screen message appears, announcing its death and which team killed it.

Respawning
When Roshan is slain, he respawns after a random time between 8-11 minutes. Unlike with other neutral creeps, the respawn cannot be prevented by any means. The players do not get any indicator for when exactly he respawns, but spectators and casters can see a clock at Roshan's spawn point, showing the exact time left for the respawn (not until 5 minutes after Roshan was slain).

Kill rewards
Each player of the killing team is rewarded with 200 gold. This causes the hero who gets the last hit to effectively gain 350-600 gold.

Upon each death, Roshan always drops the, an undroppable item once picked up, which grants the owner a second life, reincarnating it upon death after a 5 second delay at the death location. If the carrier of the Aegis of the Immortal does not die within 5 minutes after picking it up, it is removed from its inventory and fully restores its health and mana over a short period of time. The restoring is canceled upon taking any damage greater than 20, including self-inflicted damage. If the Aegis of the Immortal is not picked up and left on the ground, it disappears once Roshan respawns. The Aegis of the Immortal can be picked up by any hero (except clones, s and 's Spirit Bear). It is not restricted to the team who slew Roshan, meaning an enemy hero can "snatch" the Aegis of the Immortal. It can also be denied by attacking it.

Upon Roshan's third death and onwards, he also drops the, a completely shareable consumable item, which can be sold for 500 gold by the player who initially picks it up, or used to instantly restore 2500 health and 1000 mana. Just like the Aegis, the Cheese can also be picked up by anyone. However, it is important to note that it can only be sold by the player who was first to pick it up. Therefore, if the Cheese is transferred from Player 1 to Player 2, only Player 1 can sell the Cheese and receive 500 gold.
