Acid Hunter: Urgot fires a straight line missile that deals damage to the first enemy it hits. If an enemy is hit by a Corrosive Charge then Acid Hunter can target lock onto them, guaranteeing a hit.
Terror Capacitor: Urgot is shielded from damage and slows enemies with each hit.
Noxian Corrosive Charge: Urgot fires a corrosive missile to a location that splashes to enemies on impact, dealing damage and lowering their armor. Allows target locking with Acid Hunter.
Hyper-Kinetic Position Reverser (Ultimate): Urgot locks an enemy champion in place as he swaps positions with them, gaining armor and magic resist in the process.
Judgment now reduces the duration of new slows by 50% rather than granting immunity to slowing effects. It will still completely clear any exisiting slows when activated.
Passive: it now increases attack speed by 10/15/20/25/30% instead of giving 13/16/19/22/26% armor penetration.
Active: the projectile now reduces the target's armor by 5/10/15/20/25 for 4 seconds, instead of doubling Kog'Maw's previous passive armor penetration.
Starcall: mana cost reduced to 40/50/60/70/80 from 42/54/66/78/90.
Astral Blessing: mana cost increased to 90/110/130/150/170 from 80/100/120/140/160.
Infuse will now infuse half of the mana value to the target, and half of the value to Soraka when targeting an ally instead of giving the full value to the target. Soraka will get the full benefit of Infuse when she casts it on herself.
Elixirs will now activate immediately if purchased when your inventory is full.
