Notes

"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 if it is not currently removed from its table.
• 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:
  • Predator when not near enemy champions, and less likely to get it when in combat with nearby enemy champions.
  • Dark Harvest when near low health enemy champions.
  • Hail of Blades when near low health enemy champions and building attack speed or attack damage.
  • Conqueror when the user and other enemy champions have high health, further increased chance for melee champions.
  • Glacial Augment if the user owns an active item with a slow that is off  cooldown.
  • Fleet Footwork if the user is low health and below Level 9.
  • Summon Aery if the user has  healing and shielding power and are near a low health ally who is in combat.

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 per map, meaning it can be lower or higher depending on the mode. (The following are based on Summoner's Rift, with Dark Harvest dealing 5 damage per soul):
  • Conqueror gains (+ 2.5% per Soul) more adaptive force
    • PENDING FOR TEST: Is this per stack?
  • Fleet Footwork gains (+ 5 per soul) healing and (+ 5% per soul) bonus movement speed when activated.
  • Lethal Tempo gains (+ 5% per Soul) bonus attack speed when activated.
  • Press the Attack gains (+ 10 per soul) adaptive damage when activated.
    • Notably, the damage from Exposed doesn't increase.
  • Electrocute gains (+ 5 per soul) adaptive damage when activated.
  • Hail of Blades gains (+ 5% per soul) bonus attack speed when activated.
  • Predator gains (+ 5 per soul) adaptive damage.
    • Notably, no bonus movement speed is gained on activation.
  • Arcane Comet gains (+ 5 per soul) adaptive damage when activated.
  • Phase Rush gains (+ 5% per Soul) bonus movement speed and slow resistance when activated.
  • Summon Aery gains (+ 5 per soul) enemy adaptive damage or ally shielding when activated.
  • Aftershock gains (+ 2.5% per Soul) bonus armor and armor scaling, (+ 2.5% per Soul) bonus magic resistance and magic resistance scaling, and (+ 3.75 per Soul) more magic damage.
    • PENDING FOR TEST: Does the resistance scaling increase additively or multiplicatively?
  • Grasp of the Undying gains (+ 3.333334% per Soul) healing and damage per empowered attack, and also, (+ 5% per Soul) maximum health per stack, including ones previously gained.
  • Glacial Augment gains (+ 2.5% per Soul) slow effectiveness.
