Urgot fires a missile towards the cursor dealing 10 / 40 / 70 / 100 / 130 (+.85 of total Attack Damage) physical damage and applying his passive (does not apply other on-hit effects). Missile-lock can be achieved by holding the cursor over target afflicted by Noxian Corrosive Charge. It's missile lock range is 1200 units. It will lock onto invisible units, but it will not reveal targets hit. If Acid Hunter kills an enemy, half the mana cost is refunded.
Depends. If you already bomb-ed your target, aiming with the the Acid Hunter is that much easier - not to mention more effective.
Has quite a long range so take advantage of that
Very good for pushing champions out lanes
