Baron Nashor's pit

Baron Nashor is the most powerful neutral Monster icon.png monster on Summoner's Rift icon.png Summoner's Rift.

Killing Baron Nashor grants Hand of Baron Hand of Baron to all living teammates for 180 seconds, which grants Attack damage icon.png bonus attack damage, Ability power icon.png bonus ability power, Empowered Recall Empowered Recall, and an aura that greatly increases the power of nearby Minion icon.png minions.


Basic Attacks

Baron Nashor will attack the unit closest to him.

  • Single-target rear Attack: If the target is behind Baron Nashor, he erects a spike that deals them 100% AD physical damage.
  • Ranged attack: If the target is in front of Baron Nashor, he spits an acid missile at them that upon arrival deals 100% AD physical damage and applies two stacks of Voracious Corrosion buff.png Voracious Corrosion.
  • Melee attack: If the target is in front of Baron Nashor within about melee range, he occasionally uses a Melee role.png melee attack instead of a Ranged role.png ranged attack, dealing them 100% AD physical damage and 50% AD physical damage to nearby units.


  • Presence of the Baron: While Baron Nashor is alive, all obstructing Champion icon.png champions, Summon Tibbers.png pets, and Ward icon.png wards that are on top of him are pushed to a location in front of him. Additionally, Baron Nashor is immune to Ghost.png ghosting effects (ghosted units cannot pass through him).
    • Upon spawning in his pit, Baron Nashor Airborne icon.png knocks back all units that are within his collision radius.
  • Debuff Immunity: Baron Nashor is Cc-immune icon.png immune to all crowd control, except Stasis icon.png stasis. Additionally, Baron Nashor's stats cannot be modified by any means.
  • Baron's Gaze Baron's Gaze: Baron Nashor takes 50% reduced damage from the unit that it has most recently attacked for 8 seconds, being effective only against one unit at a time.
  • Voracious Corrosion Voracious Corrosion: Baron Nashor's attacks apply a stack to the target, each one reducing their Armor icon.png armor and Magic resistance icon.png magic resistance by 0.5, stacking up to 100 times for a total of 50 maximum resistances reduction. This lasts for 8 seconds, but will be removed 4 seconds after Baron Nashor is slain instead due to its corpse despawning.
  • Void Corruption: Basic attacks cause another burst of 70 (+ 20% AD) bonus magic damage that can occur every 0.75 seconds. This attack targets the nearest Champion icon.png champion with the lowest number of Voracious Corrosion buff.png Voracious Corrosion stacks, applying another stack.
  • Delayed Evolution: Baron Nashor waits 30 seconds after it leaves combat (dealing or taking damage) before it can level up and gain stats.


Baron Nashor will activate an ability once every 6 basic attacks. Baron's first ability will be random. However, all abilities after the first may be predicted; Baron Nashor's ability rotation is cyclical (ex. Acid Pool > Acid Shot > Tentacle Knockup > Acid Pool). If there are more units behind Baron Nashor than in front of him, he will activate the area-of-effect rear attack instead.
  • Acid Pool: After winding up for 2 seconds, Baron Nashor spits out 3 pools of acid in a cone in front of him, landing over 0.75 seconds and dealing 10% AD magic damage to all champions upon impact as well as creating a field for 2.5 seconds that Slow icon.png slows those within by 50%.
  • Acid Shot: After winding up for 2 seconds, Baron Nashor spits acid down along a straight line over 2 seconds, dealing 20% AD magic damage to all units it hits.
  • Tentacle Knockup: Baron Nashor summons a tremor beneath the target's location that erupts with a tentacle after 1.25 seconds, dealing 25% AD magic damage to units within and Airborne icon.png knocking them up for 1.25 seconds. Units near the edge of the area are also slightly knocked away.
  • Area-of-effect rear Attack: Baron Nashor erects a cluster of spikes behind him, dealing 50% AD physical damage to units within the area and Stun icon.png stunning them for 0.5 seconds.


Baron Nashor is a highly coveted objective that is difficult to fight without proper strength and personnel. A Tank icon.png tank to endure the damage is almost always required, otherwise there are few champions that can battle the monster self-sufficiently, mainly utilizing immense sustainability and DPS.

Securing Baron Nashor is a high-risk investment with the resistance-shred debuff and the confined pit providing an advantage to an intervening counterattack. Sight icon.png Sight control of the pit is also essential to securing the kill, obscuring the opportune moment to intervene and steal the objective. With these risks, fighting Baron Nashor is preferably conducted while the enemy is indisposed.
