Roshan

Roshan, sometimes also referred to as Roshan the Immortal, is a powerful neutral creep boss who easily outmatches almost every hero without the right equipment or level. As time passes, Roshan continues to grow stronger throughout the match, and respawns endlessly when defeated.

Defeating Roshan rewards the team with strong single-use items, making him a very contested unit on the map and a possible key factor to the course of a match. Due to his strength, team coordination is usually required a lot to fight him, making it also quite risky, since the enemy team could intervene at any time..

Behavior
Roshan behaves similarly to other neutral creeps, idling inside his pit when not disturbed and only attacking when aggroed.

Unlike other units, Roshan prioritizes attacking ward-type units if there are no other units within his attack range currently, even if he is being attacked by other units from farther away.

Roshan moves between his 2 Roshan Pits depending on the daytime. When day turns to night, he moves to the pit on Dire's side of the map, and when night turns to day, he moves back to the pit on Radiant's side. Roshan uses the on this journey, teleporting across the map.

Roshan Pit
Roshan can be found inside one of his pits, which are located on the far north-west and south-east corners of the map. The pits are wedged right into the two corners of the map and lie very close to the Twin Gates. The entries of the pits faces towards the center of the map. The pits' shell is U-shaped and has a length of about 1250 range and width of about 1050 range. The passable area inside the pit has a length and width of about 750 to 550 range.

Limitations inside the pits
Roshan can only be attacked from within the pits' areas, with the skull poles and the torches at the entry marking where it begins. Abilities can target Roshan from anywhere and are not restricted like attacks. Roshan himself can also attack from anywhere, he does not have to be within his pit to attack. Roshan always stays at the end of the pit when not attacking and only attacks if enemy units come within range of him, or damage him from within 1800 range.

Vision is very restricted around the pits by a vision blocker, which prevents units with ground vision from seeing past the boundary of the pits in either direction (in or out), even if they are on high ground. The vision blocker affects units and abilities alike, so if an ability grants ground vision, its center has to be within the pits to see into it. However, the vision blocker does not affect units or abilities with flying vision: they can see through it normally in both directions.

and cannot be placed inside the pits. However, the True Sight of Sentry Wards still affects unside the pit if the ward is placed just outside the pit. All other ward-type units can be placed inside it as usual. cannot be planted within the pits either, so it is not possible to block the entries off, or to create additional fog inside the pits. has a unique behavior when used inside a pit, transforming the caster into, , or into , based on how often Roshan respawned. All other spells and items function normally inside the pit.

Roshan's death
When Roshan is slain, he lets loose a deafening misc rosh death.mp3 roar, audible on the entire map, The scream is accompanied by a special piece of music stingers dota2 music stinger 009.mp3 music and an announcement from the announcer is 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 –  minutes. Roshan respawns in Radiant's pit if it is daytime, and in Dire's pit if it is nighttime. 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 unreliable gold, and the hero who deals the killing blow gets an extra random bonus of, effectively gaining. The gold is granted to all players of the team, regardless of where they are. The experience follows the default experience bounty rule, getting split between all allies within range. Additionally, all Watchers on the map are instantly captured for the side that killed Roshan, regardless of their status.

Besides a big gold and experience reward, Roshan also drops several powerful consumable items on his death. These items can be picked up by any hero and are not limited to the player or team that has slain Roshan. When selecting Roshan, the items are visible in his inventory.

Spell interactions
Roshan is an ancient creep, so that all ancient creep interactions apply, unless stated otherwise here. He also has 100% resistance to forced movement so that spells cannot move him at all. Roshan has no mana either, making him automatically immune to anything that works with mana, or null the effects of spells which are based on mana (e.g. only stuns him). Furthermore, several spells have a unique behavior towards Roshan, treating him specifically different than any other unit.

Not affecting Roshan
These spells cannot affect Roshan specifically, regardless of the ancient unit tag he has (meaning, even if he was not an ancient creep, these spells still would not affect him).
