Engineer

The  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.

Completing the Engineering Perfection challenge will unlock Engineer as a playable survivor.

Tips

 * Turrets will not receive new items that Engineer picks up after they have been deployed. Their items are only updated upon redeployment.
 * Turrets will not inherit, , , , , and.
 * Turrets will inherit Engineer's equipment, as well as any items that modify skill slots:
 * The replace the turrets' primary attack with . This increases their raw damage and proc potential significantly, and also replaces Bouncing Grenades with a significantly easier-to-use skill for Engineer himself.
 * The and   will be passed on to the turrets, but since they have no secondary or utility skill, the items have no effect.
 * The allows the turrets to throw shurikens for extra damage and range. This also gives them an easy way to activate, , and , giving them a significant damage boost.
 * Likewise, the turrets cannot use their inherited equipment unless it has a passive effect (even with ).
 * If Engineer has Elite equipment, the Turrets themselves will also become Elites.
 * The TR12 Gauss Auto-Turrets and TR58 Carbonizer Turrets have almost identical damage output and proc rate, making on-hit items like the universally good for both.
 * The turrets' attacks do not have a specific maximum range. Instead, they have a maximum distance where they will notice and attack an enemy. Notably, the TR58 Carbonizer Turrets have a much shorter maximum range than the TR12 Gauss Auto-Turrets (likely since the Carbonizer Turrets can simply walk closer to their target). This remains true even when their primary attack is replaced by Hungering Gaze.
 * Acquiring a will reduce the cooldown of Thermal Harpoons (and Hungering Gaze) to 0.5s. When using both Purity and Visions of Heresy, the turrets' raw damage output is dramatically increased to 4 times their normal amount. However, this sacrifices random chance effects like on-hit items in favor of pure damage.
 * 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 Visions of Heresy.
 * A single allows for nearly 100% uptime of Bubble Shield.
 * The Bubble Shield can be used an effective method to avoid the Genesis Supernova.
 * 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.
 * 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 percentage 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).
 * It is not recommended to obtain if using the TR12 Gauss Auto-Turrets, as the Weeping Fungus will not benefit them and they will not be able to heal Engineer.
 * 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 Bustling Fungus.
 * 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 the behavior of TR58 Carbonizer Turrets, 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.
 * 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.
 * The has a similar effect, although it corrupts all possible items into void items. This is especially pertinent for the aforementioned Bustling Fungus strategy, as they are corrupted into.
 * Engineer does not gain gold when his turrets are hit if they have the.
 * Both turrets benefit from the and have a good chance of stacking multiple Elite buffs at at time.
 * This may backfire upon killing an or  enemy, as these Elite buffs replace HP with shields, making the aforementioned healing strategies less effective (especially the Bustling Fungus 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.
 * A very risky but rewarding strategy is to acquire the at the start of a run. Both turrets get their own Fuel Array and will explode when sufficiently damaged, dealing huge damage to whatever was attacking them. This requires the player to dodge well enough to avoid exploding themself, however. This strategy is much more viable in multiplayer, as dying from the Fuel Array will not end the run.
 * Having a lets Engineer deploy 3 turrets at a time, instead of 2. Stacking more Lysate Cells will not further increase the number of turrets that can be deployed, but still provides extra charges. This comes at the cost of  equipment synergy, however.
 * Players should be aware that their turrets' kills don't count toward the user's  HP boost. Instead, their boost from the Infusion is always set to 0 when they are deployed, requiring them to each kill 100 enemies to receive the full boost. As a result, the Infusion is generally only useful for Engineer himself.
 * The will dramatically empower the turrets, giving them more attack speed, reduced cooldowns (relevant for Hungering Gaze), an extra chain gun attack, and a bonus attack akin to an . However, they will not summon their own.
