Engineer

Throw your Keg at target location, dealing 80 / 150 / 220 / 290 Magic Damage and a 1.6 / 1.9 / 2.2 / 2.5 second Stun in an area around that position.

Units hit with this ability are pushed away from the impact. You can be pushed, but not damaged or Stunned.

Deploy a Steam Turret at target location that deals 26 / 44 / 62 / 80 Physical Damage per hit. The Turret has 450 / 475 / 500 / 525 Attack Range and inherits your Inventory and 50% of the Attack Speed granted by Agility from you.

Steam Turret is unaffected by all sources of heals, Health or Mana Regeneration.

Steam Turret dies in 3 hits from melee heroes, Bosses and enemy buildings ( 6 from ranged heroes and 12 hits from other units) and does not aggro Lane Creeps. Its Health regenerates to full after not taking damage for 4 seconds.

You can destroy your own turret by attacking it.

Apply Overdrive to yourself for 4 / 6 / 8 / 10 seconds. While active, gains 25 Attack Speed per second until the end of the effect. During the effect, nearby towers and turrets receive the bonus too.

Create an Energy Field around you that deals 50 / 75 / 100 Magic Damage per second for 6 / 8 / 10 seconds with a Modulator at its center.

Enemies who enter or exit the Field have their Buffs purged, take 100 true damage and get a 2 second Silence and Perplex with a tapering 100% Movement Speed Slow.

Killing the Modulator stops the Energy Field.

Staff of the Master: Energy Field can now be thrown up to 800 units away. Energy Field now procs its effects immediately upon spawning. Now also deals 1.5% of the enemy hero's Max Health per second as Magic Damage.
