Yorick takes 5% less damage and his basic attacks deal 5% more damage for each of his active summons. All of Yorick's basic abilities summon a Ghoul . Omen of Death summons a Revenant (benefit from minion-enhancing auras).
Ghouls: Each Ghoul loses 20% of its max health each second, limiting its duration to 5 seconds. All ghouls take 50% less damage from multi-target abilities.
Each has a special effect determined by the ability used to summon it.
Ghoul Health:35% of Yorick's maximum health
Attack Damage:35% of Yorick's AD
Armor / Magic Resist: 10 + (2 × Yorick's level)
Attack Speed: 0.670
Move Speed:300 / 340 / 390 / 443
Unholy Covenant grants a self-buff while Yorick has active summons.
Ghouls count as allied minions and award gold if killed.
They lose 20% max health every second. Even if healed, they expire after 5 seconds.
Their attacks count as physical damage from Yorick.
They use Yorick's armor penetration and can trigger The Black Cleaver passive that reduce armor.
They can make a maximum of 3 basic attacks before they expire.
They will initially attack the target of the spell which summoned them, then prioritizing enemy champions, minions, and turrets, in that order.
They will pursue a champion until they die or lose sight of them.
They take 50% reduced damage from AoE spells.
Only one Ghoul of each type can exist simultaneously. Summoning a duplicate destroys the oldest.
Omen of War
COST: 40 mana
COOLDOWN: 9 / 8 / 7 / 6 / 5
Active: Yorick's next basic attack within 10 seconds will deal bonus physical damage and summon a Spectral Ghoul.
Spell shields will block the damage and prevent the ghoul from being summoned.
The initial heal is calculated post-mitigation.
The on-attack heal is independent of any damage dealt.
Omen of Death
COST: 100 mana
COOLDOWN: 120 / 105 / 90
Active: Yorick conjures a Revenant in the image of an allied champion. If that ally takes lethal damage before the Revenant dies, the Revenant sacrifices itself to reanimate them and give them 10 seconds to enact vengeance.
Revenant: A Revenant lasts 10 seconds. It has health and attack damage calculated from the target's totals.
Revenant Health: 50 / 75 / 100% of the ally's health
Attack Damage: 45 / 60 / 75% of the ally's AD
Omen of Death can target a single allied champion.
Any other revive will trigger first because this revive is temporary.
This revive effect differs greatly from all other revive effects.
The ally has full health restored.
It puts the ally where the Revenant was. Possibly to inform them that the effect occurred and they have 10 seconds left to act.
There is no stasis or inactive period.
Items which lose stacks upon death will do so before the revive and not after. The loss of stacks only occurs once, as normal.
Is a pet yet counts as a champion for aura effects.
Will have the on-hit effects of the ally but not their auras, runes or masteries.
The Revenant only has a percentage of the target champion's Attack Damage while it is under Yorick's control.
Thus if the allied champion dies and takes control of the Revenant, it will gain 100% of the champion's Attack Damage regardless of Omen of Death's rank.
