Engineer

Tips

 * Engineers gain a lot of utility from the Missile Drone and Guardian starter items. Almost all summon items scale well throughout the game, but the Missile Drone in particular gets extra damage from recycling items.
 * It may be prudent to immediately recycle any shot-triggered passive items with friendly fire risk. Your drones can inadvertently trigger those items with their weapon shots and create some unpleasant surprises.
 * Your summons, including your Sentry Turret, count as enemies for the purpose of lifesteal and Healing Crystal power.
