Slaying the Rift Herald drops the Eye of the Herald at the entrance of the pit, which grants Empowered Recall and the ability to summon the Rift Herald to push a lane. The Eye of the Herald can be picked up by one member of the slayer's team and despawns 20 seconds after it drops.
The Rift Herald spawns up to two times per game. It despawns permanently at 19:45, or 19:55 if in combat. The second Rift Herald only spawns if the first one is killed before 13:45. If the first Rift Herald is killed when the timer shows exactly 13:44, the second Rift Herald will spawn at 19:45 and instantly despawn. Baron Nashor spawns in the same position at 20:00.
The level of the Rift Herald is the average of all champions' levels when she spawns, with a minimum of level 6.
Colossal Strength: The Rift Herald's basic attacks deal 4% of target's current healthbonus physical damage.
Monstrous Toughness: Effects that deal damage based on the Rift Herald's health and are not usually capped, are capped at 50 damage.
The Eye of Baron: The Rift Herald has a vulnerable eye on her back. Champion basic attacks against it deal 12% of Rift Herald'smaximum healthbonus true damage. When the eye is hit, it closes for 10 seconds, reduced by 2.5 seconds every time she is struck by a champion's basic attack. The eye doesn't open more than once every 3 seconds or if the Rift Herald is below 15% maximum health.
Charge: At the start of the fight, the Rift Herald winds up for 2.5 seconds to leap forward, dealing 200% ADphysical damage to enemies within her path and knocking them aside, though not through terrain.
While in the pit, she charges at the current location of the enemy who first damaged her.
Swipe: At 65.75% and 32.75% of Rift Herald'smaximum health, she winds up for 1.5 seconds to strike in a cone in front of her, dealing 300% ADphysical damage to enemies hit.
The Eye of the Herald can be crushed to summon the Rift Herald. The summoned Rift Herald relentlessly pushes her way to the enemy Nexus. The summoned Rift Herald has different statistics, effects and abilities than the pit Rift Herald:
She heads to the closest lane and start pushing it.
She focuses mainly on the closest minions and targetable structures.
Her level is the average of the levels of the champions of both teams the moment the Eye is picked up.
She grants her kill credit to the champion she was summoned by; any unit she kills and any turret plate she destroys is accredited to the summoner, granting them the gold.
Her basic attacks deal 1.75% of Herald'scurrent healthbonus physical damage and knock back all enemy minions in front of her.
The Eye of Baron: Every 3 seconds, the eye on Rift Herald's back will open. Champion basic attacks against the eye deal 40% of Rift Herald'smaximum healthbonus true damage.
Leap Attack: When the Rift Herald approaches a targetable structure, she winds up for 2.5 seconds to leap into her attack range of the structure. Upon arrival, she headbutts the structure, dealing 2000 − 2750 (based on level)true damage to it, 200% ADphysical damage to nearby enemy champions and knocking them back, and 66% of her current health as true damage to herself if she damaged the structure.
She can be teleported even while winding up on a structure or during her leap. She will still start her charge even after blinking during the windup (unless her windup completes during the 0.75 seconds where she is unable to act, in which case she will not start her charge).
The Rift Herald can be targeted by Teleport while in summoned form.
The summoned Rift Herald has a hefty amount of health and damage and several skills focused on taking down towers. The leap deals the same amount of damage regardless of current health, enabling the Rift Herald to rapidly destroy multiple turrets if left unchallenged.
Since a summoned Rift Herald prioritizes minions and structures, it is not possible to distract it from smashing towers. The only way to stop the Rift Herald is to take it down.
In its neutral monster form, the Rift Herald will dance if a champion dances nearby. In its summoned form, she will dance if she is still alive when a Nexus from either team is destroyed.
If the Rift Herald is in range of two structures and winds up to charge at a structure that gets destroyed before she starts to charge, she will charge to the next available structure instead from the same wind-up.
In patch V7.9, it was stated that Rift Heralds were exclusively female.
From patch V5.22 to patch V7.9, the Rift Herald had a wildly different appearance. It can be seen in the 'Skins' tab.
While she looked like this, her animations were recycled from the Blue Sentinel's.
Bug Fix: Fixed a bug where canceling Eye of the Herald's summoning ritual at the very end of its 0.25 seconds wind-up (before the uncancellable 3-second channel begins) could cause the item to go on an extremely long cooldown, preventing it from being used before it expires.
New Effect: Rift Herald is captured in the Eye of the Herald when killed. Any member of the team that killed Rift Herald can pick it up, temporarily replacing their trinket. Eye of the Herald grants Empowered Recall while held and expires after 4 minutes if not used. Channeling Eye of the Herald for 3.5 seconds will crush it to summon Rift Herald from the void as your team's ally.
Has 4000 - 6400 health, 425 movement speed, 80 - 200 attack damage.
Basic attacks deal 3% of Herald's current healthbonus damage, in addition to base AD.
When Rift Herald approaches turrets she winds up and leaps into melee range, dealing 150 damage (+ 25% of her current health) to the turret and herself.
Eye opens every 3 seconds.
Poking Rift Herald's eye deals 20% of her maximum health as damage.
Rift Herald can be affected by most forms of crowd control.
Rift Herald disables turret backdoor defenses even when no allied minions are nearby.
While there are no allies nearby, you take 5% damage reduction from enemy champions and generate X / Y (based on level) Corruption stacks per second. At 100 stacks, your next basic attack consumes all stacks to deal 15 / 270 (based on level) bonus magic damage. Works versus structures, damage halved for ranged champions.
Lasts for 20 minutes and is retained even if slain.
