This role focuses on 2 parts for Early and Mid.

*Lane Domination thru Blast Off*
With focusing on Tranquil Boots, Cloak and Soul Ring, high life regen with Magic Resistance enables superior damage into the enemy.
For Laning, the first 3 levels, let whoever it is farm. Focus on hitting enemies and threatening them with Blast Off.

To compensate farming, at lv5 the Prox Mines will clear any lane and some creep camps.

*Techies Farm Security Services*
By securing all the ramps on your side of the map with dual Prox Mines and center Statis, no one is coming into the Jungle or Triangle without triggering something. Invisible or otherwise.
With extra "Safety" Prox+Statis spots immediately behind the tower, enemy cannot dive successfully either.

This enables security for your 1 and 2 to farm happily, zoning out the opponent. With proper pressure, you will generally control more than half the map's farm.

For late game, its very open in terms of what happens. Generally employ the usual ambushes with Remotes and place Prox+Statis on all the routes.
If the team is pushing, hang back with a trail of Prox and Statis and Remotes to "fake" retreat to.
