Engineer

The Engineer is one of the playable characters in Risk of Rain 2.

How to Unlock
The Engineer is unlocked upon completing the Challenge "Engineering Perfection" (Complete 30 stages.)

Tips

 * Getting several Bustling Fungus and stacking TR12 Gauss Auto-Turrets on top of each other is a great way to cheese certain bosses. This isn't as effective on the Magma Worm as it tends to knock the Engineer out of the healing radius or outright destroy the turrets, but the Turrets' auto-aim may make this boss easier to fight nonetheless.
 * Getting plenty of AoE and/or proc items for your TR58 Carbonizer Turrets (like Sticky Bomb, Ukulele, Will-o'-the-wisp, Sentient Meat Hook, etc.) and some healing items for the early game (like Monster Tooth) will turn them into fairly self-sufficient powerhouses. If you manage to get the right items, both damage and defense wise, these turrets will pretty much clear stages by themselves!


 * A single Hardlight Afterburner can allow for 100% uptime of Bubble Shield.
 * Stacking Bandolier can lead to a constant up time of your Bubble Shield, allowing for good cover from Wisps and Titans/Colossi as the game progresses. It also proves useful to refresh your Turrets' cooldown, giving you a backup in case one of them gets destroyed.
 * Pressure Mines can be stuck onto the outside surface of the Bubble Shield, as well as other players and friendly entities such as Utilities.
 * Leeching Seed is a high priority item, as it heals your Turrets as they deal damage.
 * You may sprint while Bouncing Grenades is charging up. Deploying Bubble Shield will not stop sprinting.
 * Acquiring Rejuvenation Rack, N'Kuhana's Opinion, and as many Bustling Fungus as possible will allow your turret's to spawn many of the flaming skull projectiles as you and both your turrets will all heal each other causing N'Kuhana's Opinion to proc.
 * TR12 Gauss Auto-Turret and the TR58 Carbonizer Turret will not receive new items their Engineer picks up after deployment. Their items are only updated upon redeployment.
