Current abilities
  • Sticky BombLobs a Sticky Bomb towards the target area. If it lands next to an enemy hero, the bomb will stick to it, slowing its movement speed. After a few seconds the bomb will explode, dealing damage in an area around the detonation and applying a secondary slow for 3 seconds.
  • Reactive TazerTechies trigger an electric charge on the target ally, giving them bonus movement speed for a short period of time. Enemies attacking the target take damage and are temporarily disarmed and get a Basic Dispel. At the end of the effect or if detonated early with the sub-ability, the charge explodes, disarming all enemies within the radius and dealing damage.
  • Blast Off!Techies hurtle themselves into the enemy's midst, detonating charges upon impact which deal massive area of effect damage and stun enemies. Upon landing, the assault deals Techies non-lethal damage equal to a percentage of their current health.
  • M.A.D. innateTechies gain a percentage of their mana pool as bonus mana regeneration. When Techies die, they leave behind a barrel that explodes after 1.5s, damaging enemies in an area around it. Damage is based on Techies' max mana.
  • Minefield SignPlant a warning sign, causing Proximity Mines within its radius to be invulnerable and deal 15% more damage. Only one sign can exist at a time. Lasts 240 seconds. When an enemy Hero walks within 200 units of a minefield sign, the 1000 units area around the sign will become a minefield for 10 seconds, dealing damage to enemy Heroes any time they move within its area. Minefield Sign is destroyed after this effect ends.
  • Proximity MinesPlant an invisible mine that cannot be detected by True Sight, but is visible if an enemy is within the active 500 AoE of the mine. Mines detonate if an enemy is standing within the active AoE for 1 seconds dealing damage and temporarily reducing the enemy's Magic Resistance. The explosion deals full damage if the target is within 150 radius and decreases down to 50% on the edge. Deals 30% damage to buildings.
