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 gain the same Items that Engineer himself has. This makes him unique, as item selection doesn't necessarily come down to what benefits himself, but also what can benefit his turrets.

Tips

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


 * Placing Spider Mines on elevated positions may allow them to jump onto airborne enemies. They can also be placed onto allies and other Survivors, unlike the immobile Pressure Mines.


 * Stacking can lead to constant uptime of Bubble Shield, allowing for good cover from Wisps and Titans as the game progresses. It also proves useful to refresh the Turrets' cooldown, giving the player backups in case one of them gets destroyed.
 * Be wary that TR58 Carbonizer Turrets can pick up ammo packs by walking past them. This may not be an issue if they have.


 * A single allows for 100% uptime of Bubble Shield.


 * The Bubble Shield can be used an effective method to avoid the Genesis Supernova.
 * It also can block the wheel of flame, and should last for the entire duration of the attack.


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


 * Turrets will not inherit, , , , , and.


 * TR12 Gauss Auto-Turrets can block each other's shots if they're placed too close to each other, so some care must be taken to space them out just enough to still benefit from items such as.


 * Stacking several and placing TR12 Gauss Auto-Turrets beside one another is an effective method for dealing with bosses and high-damage enemies, as it provides a small zone of healing readily defended with the addition of a deployed Bubble Shield. Be wary that melee-oriented monsters may still knock Engineer out of the healing radius or the shielded area.
 * It is not recommended to pick up if using the Bustling Fungus strategy, as Bustling Fungus heals based on a % of max HP (which will become 1). If the player wants to use the Transcendence/ combo, they should use alternative forms of healing such as  or.
 * Acquiring, , and as many as possible will allow the stationary TR12 Gauss Auto-Turret to unleash a constant barrage of attacks, as the player and both their turrets will all heal each other (causing N'Kuhana's Opinion to continuously activate).


 * Getting plenty of AoE and/or on-hit items for the player's TR58 Carbonizer Turrets (like, , , , etc.) as well as some healing items for the early game (like ) will turn them into fairly self-sufficient powerhouses.


 * One method to amass large amounts of healing on TR58 Carbonizer Turrets during mid-game or late-game is to stack and enough  to reach guaranteed critical strike chance, preferably with a  for bonus attack speed. The constant, rapid critical strikes will heal the turrets as long as they have targets to attack.


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


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


 * Turrets 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 Engineer has not used up his own Dio's Best Friend.


 * Both turrets benefit from the, most likely stacking multiple buffs gained from Elite enemies.
 * This may backfire upon killing an Overloading or Perfected enemy, as this replaces HP with shields and makes the aforementioned healing strategies less effective, especially the strategy.


 * TR12 Gauss Auto-Turrets can be used to press the pressure plates on Abandoned Aqueduct.
 * Though TR58 Carbonizer Turrets can activate them as well, these turrets are liable to walk off the pressure plates.

Trivia

 * The Engineer was one of the playable characters in the first Risk of Rain.
 * Prior to the Anniversary Update, the Engineer's ending phrase was "...and so he left, more steel and circuit than man.", reiterating his ending message from Risk of Rain.
 * For some reason, the TR58 Carbonizer Turrets will not follow the player around on the Nintendo Switch version.
