Techies

The Goblin Techies or Goblin Sappers are as yet unreleased heroes (slated for release after The International 2014).

Having little direct combat ability, the Goblin Techies have an unorthodox, if effective, method of dealing damage to the enemy team in the form of powerful laid explosive mines and stasis traps that enable other heroes to set up a gank or retreat. Their mines, set across key points of the map -and even less conventional locations- are an effective method of denying area and guaranteeing damage if enemies dare to initiate.

They have an even more bizarre 'skill' in the form of their Suicide Squad, Attack! which causes them to violently explode and die but deal massive damage (at early - mid game) in a moderate area of effect.

The unique mechanics of the mines mean that the Goblin Techies utilise mechanics not used by any other hero, including preemptive mine concaves and such strong area denial that they actively play a large role in securing the area controlled by friendly heroes.

The Goblin Techies have statistics aligned to those of semi-carries, but largely play a passive, defensive role throughout the game. Their unique utility is slowly lost throughout the latter part of the game, but as with other supports their long cooldown skill Suicide Squad can still be quite effective.
