黄铜爆音

Replace a summoner spell with Brass Blast. Brass Blast - Active: You summon a large trumpet in front of you and begin charging for a minimum of 0.25 seconds and up to 2.5 seconds to increase Brass Blast's range, damage, and knock back distance over the first 1.5 seconds of the channel. While charging, you are slowed by 10% and can reactivate the spell. The recast occurs automatically if the charge reaches its maximum duration or is interrupted. Recast: After a 0.5-second delay, blow into the trumpet, unleashing a blast of sound in a cone in the target direction that deals between 120 – 140 (based on level) (+ 70% bonus AD) (+ 50% AP) to 200 – 600 (based on level) (+ 115% bonus AD) (+ 80% AP) magic damage to enemy champions hit and knocking back all enemies hit up to 500 units over 0.75 seconds. If the charge is interrupted, 50% of the cooldown is refunded. Brass Blast uses quick casting by default, which requires the active to be held and the recast to occur on release. The cone has an initial radius of 700 units. Knock back speed is 1300.
