The new champion Gnar has been released on PBE, and one of is skills is a jump.
According to the champion page,
Gnar jumps in a target direction and gains a moderate attack speed boost. If Gnar lands on a unit, he bounces, hopping again in the same direction. If Gnar hops onto an enemy unit, he also damages and slows them.
If he continues to land on units, does he continue to hop, or would he stop?
