Roshan



Roshan, sometimes also referred to as Roshan the Immortal, is the most powerful neutral creep in Dota 2. It easily outmatches most heroes in one vs one combat. A team generally waits until later in the game where the damage dealers have better items, or tries to take it on with the entire team.

Every 4 minutes (starting at first lane creep spawn) Roshan gets stronger, gaining 20 extra Slam damage, +500 hp, +10 damage and +0.5 armor (given by an aura).

Respawning


Roshan respawns randomly between 20-30 minutes after he was last killed. His respawning cannot be stopped (unlike other neutral creeps) by placing wards and/or standing in his area.

Abilities
Roshan has four abilities at his disposal:

Aegis and Cheese
When Roshan is killed, he always drops an Aegis. Once picked up, this item cannot be dropped or given to another hero. When the carrier of Aegis dies, a tombstone spawns on the corpse. After five seconds the hero respawns with full hp and mana on top of the tombstone, which consumes the Aegis. If the Aegis carrier does not die within five minutes of picking it up, the Aegis is removed from the carrier's inventory, and subsequently, is returned to Roshan, along with regenerating their Health and Mana to full, but this buff dispels upon taking damage.

After Roshan has been killed two times, on his next respawn he begins to carry Cheese along with an Aegis. Cheese can be shared with allies, or sold for 500 gold. When used, it will instantly restore 2500 hp and 1000 mana to the user.

Protected area
Units must be within Roshan's spawn location in order to attack him. Roshan, however can attack anyone in his attack range, even if he is not in his cave. Units outside of his cave cannot see inside without going into it. So, units that are attacking Roshan will not be seen by other enemies outside of the cave, unless an ability that gives vision such as Templar Assassin's Psionic Trap, Invoker's Sun Strike, Ancient Apparition's Ice Vortex, or Clockwerk's Rocket Flare is used inside of the pit.

Trivia

 * Roshan was named after Guinsoo's bowling ball.
 * According to the Are We Heroes Yet? comic, Roshan killed a Shopkeeper, thus claiming the Aegis of the Immortal, and being cursed to have his treasure stolen from him again and again.
