Minions (known as Creeps in Defense of the Ancients: Allstars) are expendable units that are trained automatically to charge into battle with the purpose of attacking enemy units in the lanes they are assigned.
The blue and purple team minions spawn every 30 seconds from the Nexus in order to support the champions. Minions begin spawning 1 minute 30 seconds after the game has begun. Every 3 minutes the minion waves will grow stronger, with every type of minion gaining different stats. Minions deal 50% increased damage to turrets and deal about 15% reduced damage to enemy champions. Minions should not be confused with monsters, which are neutral unless attacked and reside in the jungle. (Read more on Wikia)
