Engineer

The Engineer is a playable character in Risk of Rain 2.

With an assortment of deployable gadgets, the Engineer's strength comes not from him alone, but rather his ability to set up a variety of defensive measures.

The Engineer's signature ability is his deployable turrets, which inherit his collected Items. This makes him unique as item selection doesn't exactly come down to what benefits himself, but rather what benefits his turrets most.

Tips

 * Getting several and stacking TR12 Gauss Auto-Turrets beside one another is an effective method for dealing with bosses and high-damage enemies, as a it provides a small zone of healing readily defended with the addition of a deployed Bubble Shield. This isn't as effective on the  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.


 * TR12 Gauss Auto-Turrets can block one another's shots depending on how they're placed, so some care must be taken to space them out just enough to still benefit from items such as.


 * Getting plenty of AoE and/or proc items for your TR58 Carbonizer Turrets (like, , , , etc.) and some healing items for the early game (like ) 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 can allow for 100% uptime of Bubble Shield.


 * Both the TR12 Gauss Auto-Turrets and TR58 Carbonizer Turrets would benefit from getting, most likely stacking multiple buffs gained from elite enemies.


 * Moving the targeting reticle of Thermal Harpoons off of a target resets the lock on delay, allowing you to immediately target them again. This means that by wiping the reticle back and forth over a single or multiple targets, you can lock on much faster.


 * Stacking 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.


 * Both Pressure Mines and Spider Mines can be stuck onto the outside surface of the Bubble Shield. is highly useful for both mines.


 * Placing Spider Mines on elevated positions may allow them to jump onto airborne enemies. Similarly they can be placed onto NPCs and other survivors in a coop situation unlike the immobile Pressure Mines.


 * An easy way to amass large amounts of healing on TR58 Carbonizer Turrets during mid-game or late-game is to stack for healing on crit and +5% crit chance,  for attack speed buffs on crit and another +5% crit chance, and at least 9   for +90% crit chance. This combination of items results in guaranteed crits as well as healing from every instance of damage dealt that increases with the amount of  the turrets have.


 * Due to their faster firing speed, TR58 Carbonizer Turrets are better at proccing certain item such as, , and . and  may improve them further (though these are universally good on both turrets).


 * Due to the AI behavior of TR58 Carbonizer Turret, might be useful when they eventually haphazardly charge into enemies. A  and a few  or  can allow them to turn this caveat into a positive.


 * You may sprint while Bouncing Grenades is charging up. Deploying Bubble Shield will not stop sprinting.


 * Acquiring, , and as many as possible will allow the stationary TR12 Gauss Auto-Turret 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 continuously 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.


 * Both turrets greatly benefit from as the 3 second invincibility time will always reset on newly deployed turrets as long as the Dio's Best Friend has not been used up on the Engineer himself. This is an especially important item during Monsoon runs.


 * can be used to offset the long cooldown of the turrets, though TR58 Carbonizer Turrets can pick the ammo packs up by walking atop them. This may not be a problem if you and your turrets have.


 * The TR58 Carbonizer Turret still benefit from attack speed even though they shoot lasers, i.e. 1 makes them go from 2-3 hits per second to 4-5.


 * TR12 Gauss Auto-Turrets can be used to press the pressure plates on Abandoned Aqueduct.


 * Though TR58 Carbonizer Turrets can activate the pressure plates on Abandoned Aqueduct, they cannot be practically relied on to remain standing on them.
 * The Bubble Shield can be used an effective method to avoid the Wandering Vagrant's explosion attack.
