Guys, Ekko's W passive only works when a target is below 30% HP
Every post so far I have read, everyone is saying his W passive does %HP damage to the target at any time. NO it is only against targets with 30% HP or lower
Parallel Convergence [ W ]
Cooldown: 22/20/18/16/14 seconds || Mana Cost: 30/40/50/60/70
Passive: Ekko’s basic attacks deal bonus magic damage to enemies under 30% health, equal to 5% [ +1% per 45 AP ] of their missing health (capped at 400 damage vs. minions and monsters).
