To the Skies! does not follow the target's movements; if the target uses a movement ability or Flash, Jayce will still land at the target's original position.
To the Skies! will bring Jayce to a location linearly in front of his target.
Shock Blast briefly reveals Fog of War in the area where it explodes.
Shock Blast's range increase when used with Acceleration Gate is not affected by when the projectile actually passes through the gate; the boost simply re-targets Shock Blast to reach a location further along the same path of travel, but further away from Jayce's original position.
Lightning Field and Hyper Charge have no cast time and do not interrupt Jayce's previous orders.
Hyper Charge will reset Jayce's attack timer on cast.
Hyper Charge goes on cooldown after the third shot and not on cast.
Hyper Charge will grant Jayce maximum attack speed (2.5) by itself. However, combined with attack speed reductions such as WitherNasus, he may not achieve maximum attack speed.
The enhanced attacks can critically strike and will stack with critical strike damage multiplicatively (i.e. at rank 5 a critical strike with no modifiers and Hyper Charge active will deal 110% × 2 = 220% damage).
The buff lasts for 4 seconds, total, regardless of how many attacks were used.
Active: Jayce swings his hammer at target enemy, knocking them back over 0.75 seconds and dealing magic damage equal to a percentage of their maximum health plus Jayce's bonus attack damage. This damage is capped against monsters.
Total Magic Damage:8 / 11 / 14 / 17 / 20% of target's maximum health(+100% bonus AD)
Max Damage to Monsters: 200 / 300 / 400 / 500 / 600
Similarly with HeadbuttAlistar, the target is "suppressed" for the duration it would take to travel the entire distance of the knock-back, if the target is knocked back near a wall or structure and cannot travel the whole distance.
Acceleration Gate has no cast time and does not interrupt Jayce's previous orders.
Acceleration Gate does not increase the movement speed of pets or minions.
Acceleration Gate reveals Fog of War in the area where the gate generators are.
Active: Transforms the Mercury HammerMercury Hammer into the Mercury Cannon, gaining new abilities and ranged attacks. Jayce gains 375 range (500 total range).
The next attack in Cannon Stance reduces the enemy's armor and magic resist for 5 seconds.
