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 the projectile to reach a location further along the same path of travel, but further away from Jayce's original position.
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).
Similarly with Alistar'sHeadbutt, 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.
