  • Conqueror Conqueror or Press the Attack Press the Attack cannot be gained as the first keystone.
    • The Exposed debuff from Press the Attack Press the Attack will increase the damage of any subsequent damaging Keystones by 8% − 12% (based on level), so long as the Keystone is triggered prior to the Exposed debuff expiring.
  • Omnistone Omnistone can still grant Predator Predator if the user has Magical Footwear Magical Footwear but has not been granted the boots yet.
    • This can only happen once, as once Omnistone Omnistone refills its table of Keystones, Predator Predator can no longer be rolled if the owner does not have boots in their inventory.
    • This can also happen to Cassiopeia Cassiopeia, who can neither purchase boots, nor can she take Magical Footwear Magical Footwear.

"Smart" Keystone Chances[]

  • "Smart" selection takes place before Omnistone rolls its table of Keystones; if an ideal situation is found it will have an 8 - 15% increased chance to roll the relevant Keystone.[1] If you would otherwise not roll a relevant Keystone due to it being removed from the table, Omnistone Omnistone will refill its table of Keystones, and grant you the relevant Keystone.
  • "Smart" selection cannot grant you the same Keystone consecutively.
  • A specific Keystone will be given to the user under many circumstances fit for the gameplay scenario. The following have an increased chance to be given:
    • Conqueror Conqueror when the user and other enemy champions have Champions killed with Comeuppance (R)high health, further increased chance for melee champions.
    • Fleet Footwork Fleet Footwork if the user is Champions killed with Comeuppance (R)low health and below level 9.
    • Dark Harvest Dark Harvest when near Champions killed with Comeuppance (R)low health enemy champions.
    • Hail of Blades Hail of Blades when near Champions killed with Comeuppance (R)low health enemy champions and building Champions hit with Martial Cadence (P)attack speed or Champions hit with Bandage Toss (Q) at greater than 75% of max rangeattack damage.
    • Predator Predator when not near enemy champions, and less likely to get it when in combat with nearby enemy champions.
    • Summon Aery Summon Aery if the user has  healing and shielding power and are near a Champions killed with Comeuppance (R)low health ally who is in combat.
    • Glacial Augment Glacial Augment if the user owns an active item with a slow that is off  cooldown.
  • If you are a Melee champion, the bonuses from Conqueror Conqueror and Lethal Tempo Lethal Tempo last longer than the cooldown of Prototype: Omnistone Prototype: Omnistone, which can affect "Smart" selection, as well as empower other keystones.

Dark Harvest Dark Harvest Soul Bonuses[]

  • The following Keystones have their stats enhanced based on the number of Dark Harvest stacks. Soul bonuses are relative to the damage per stack of Dark Harvest Dark Harvest per map, meaning it can be lower or higher depending on the mode.[2] (The following are based on Summoner's Rift, with Dark Harvest dealing 5 damage per Rend (E) stacks transferred to champions with Pierce (Q)soul):
    • Conqueror Conqueror gains Rend (E) stacks transferred to champions with Pierce (Q)(+ 2.5% per Soul) more adaptive force.
    • Fleet Footwork Fleet Footwork gains Rend (E) stacks transferred to champions with Pierce (Q)(+ 5 per soul) healing and Rend (E) stacks transferred to champions with Pierce (Q)(+ 5% per soul) Champions killed 5s before or after using Chronobreak (R)bonus movement speed when activated.
    • Lethal Tempo Lethal Tempo gains Rend (E) stacks transferred to champions with Pierce (Q)(+ 5% per Soul) Champions hit with Martial Cadence (P)bonus attack speed when activated.

    • Phase Rush Phase Rush gains Rend (E) stacks transferred to champions with Pierce (Q)(+ 5% per Soul) Champions killed 5s before or after using Chronobreak (R)bonus movement speed and slow resist when activated.
      • It is possible to reach and exceed 100% slow resist, and thus become immune to slows.
    • Summon Aery Summon Aery gains Rend (E) stacks transferred to champions with Pierce (Q)(+ 5 per soul) enemy adaptive damage or ally shielding when activated.

    • Glacial Augment Glacial Augment gains Rend (E) stacks transferred to champions with Pierce (Q)(+ 2.5% per Soul) slow strength.

Strategy[]

Omnistone's Omnistone's best use scenario is not maximizing the potential of every keystone, but rather to dispense the keystones you use least effectively in order to gain access to your most efficient ones. As such, if there are keystones you can roll, but cannot dispense due to a champion's inherent kit design (e.g Karthus Karthus, or Anivia Anivia, whose kits do not allow much use of auto attacks), Omnistone is most likely to not be the best fit for you.

General tips:

If you are a melee champion:

  • Due to the lack of target access that melee champions inherently have as a range class, maintaining your distance to increase the likelihood of rolling Predator Predator will allow you to better access your targets, or to enhance any existing engage spells, such as Nunu's Nunu's Biggest Snowball Ever! Biggest Snowball Ever! or Warwick's Warwick's Infinite Duress Infinite Duress.
  • Conqueror's Conqueror's probability to be rolled is based on the  Champions killed with Comeuppance (R)percent current health of nearby enemies, which makes your likelihood of rolling Conqueror Conqueror greatest in a teamfight.
    • Paired with the above point, using Predator Predator to close the gap and access high priority targets, and subsequently rolling Conqueror Conqueror increases your likelihood of fully stacking the keystone, giving you immense combat power.
  • For melee champions, Prototype: Omnistone Prototype: Omnistone has a [5-3] second scaling cooldown. The following buffs persist long enough that they can help you proc other keystones, empower subsequent keystones, as well as impact Smart Selection:
    • Conqueror Conqueror
      • If you are an  Champions stunned with Pyromania (P)AD champion, fully stacking Conqueror will increase the likelihood of rolling Hail of Blades Hail of Blades.
    • Lethal Tempo Lethal Tempo
      • The buff can last up to 6 seconds after an initial delay, allowing to possibly dispense up-to 2 keystones during its duration.
      • The boost in  Champions hit with Martial Cadence (P)attack speed increases the likelihood of rolling Hail of Blades. As such, it is possible to obtain a minimum boost of up to 220% attack speed for 3 auto attacks, which can burst unsuspecting targets in a fight.
        • This is especially beneficial for melee champions who build  Time champions spent slowed by Miasma (W)Critical Strike Chance, such as Tryndamere Tryndamere, Yasuo Yasuo, and Yone Yone, as with enough Critical Strike Chance, they can potentially critically strike 3 times in rapid succession.
    • Grasp of the Undying Grasp of the Undying
      • The healing and resulting health gain can push you into the threshold to boost the likelihood of rolling Conqueror.
    • Glacial Augment Glacial Augment*
      • *If triggered by an active item with a slow.


If you are a ranged champion:
