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. During the early to mid game, he easily outmatches almost every hero in one-on-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 left of the top river rune spot. The pit is completely inside the river, with the river splitting up at its entrance and merging again right behind the pit. The entry of the pit faces south-east, towards the mid lane. The pit 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.

Roshan's exact location on the map is (x = -2464.245, y = 2016.373).

Limitations inside the pit
Roshan can only be attacked from within that area, with the torches at the pit entry marking where it begins. Spells 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 pit by a vision blocker, which prevents units with ground vision from seeing past the boundary of the pit in either direction (in or out), even if they are on high ground. The vision blocker affects units and spells alike, so if a spell grants ground vision, its center has to be within the pit to see into it. However, the vision blocker does not affect units or spells with flying vision: they can see through it normally in both directions.

and cannot be placed inside the pit. However, Sentry Wards placed outside of it, and their True Sight area overlapping with the pit will function normally. All other ward-type units can be placed inside it as usual. cannot be planted within the pit either, so it is not possible to easily block the entry off, or to create additional fog inside the pit. has a unique behavior when used inside the 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 Roshan Death.wav roar, audible on the entire map, The scream is accompanied by a special piece of Music default dota2 music stinger 009.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 reliable gold, and the hero who deals the killing blow gets an extra random bonus of ‒ gold, effectively gaining – gold.

Upon each death, Roshan always drops the, an item which cannot be dropped once picked up. If the hero who picked it up dies, they reincarnate at their death location after a second delay. 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. This restoration can be canceled by taking any player-based damage, 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, illusions, and creep-heroes). It is not restricted to the team that slew Roshan, meaning an enemy hero can "snatch" the Aegis of the Immortal. It can also be denied by attacking it.

Upon Roshan's second death and onwards, he also drops the, a completely shareable consumable item, which can be sold for gold by the player who initially picks it up, or used to instantly restore  health and  mana. Just like the Aegis, the Cheese can also be picked up by anyone. However, 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.

Upon Roshan's third death and onwards, he also drops either the, or the , both having an equal chance of appearing. On his fourth death and onwards, he drops the Refresher Shard and the Aghanim's Scepter (Consumable), on top of dropping the Aegis of the Immortal and the Cheese.

The Refresher Shard is another completely shareable consumable item, which can also be sold for gold by the player who initially picks it up, or used to instantly restore the cooldowns of all abilities and items, and restore all charges of charge-based abilities of the user. The Refresher Shard can be picked up by anyone as well. But just like the Cheese, it can only be sold by the player who was first to pick it up.

The Aghanim's Scepter (Consumable), when dropped by Roshan, cannot be sold at all, unlike the bought version from the shop. Unlike the Cheese and Refresher Shard, it is not sharable, and gets bound to the player who picks it up.

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).

Forced movement interactions
Forced movement and teleport spells react differently to forced movement immunity. All not-listed forced movement or teleport spells cannot affect Roshan due to his status.

The following spells completely apply all their effects except for the movement itself. This includes the disable coming along with the movement.

2 Roshan gets stunned, instead of getting lifted. The AoE stun is applied instantly, since it is queued to happen after the lift, which gets fully skipped.

The following spells apply all effects as well, except for the disable along with the movement, so that they do not even interrupt Roshan.
