This section is for all the TLDR people if all you want is our personal pointers and tips here you go.
- Maximizing In the Zone uptime (30-70 volatility) translates into buff uptime.
- Minimize dead GCD time and maximize counts of hardest hitting abilities
- Learn to sprint to avoid telegraphs, dashes should be saved for rotational needs to stay in the zone.
- Prioritize Bio Shell whenever it is off cooldown. It does the most DPS.
- Being strikethrough capped translates into a solid rotation of Bio Shell, 3x Bolt Caster, repeat.
- Use VI, Barrage, Strobe, Quick Burst, and Innate as often as possible, but Innate can and should be saved for times when burst is needed.
- Do not be afraid to run T4 RM and Repair Bot. RM is an extremely potent raid damage absorb and Repair Bot is great at shield heals.
- Keybind Primary Pet Action Bar Slot 3 (this kills your bots) and Primary Pet Action Bar Slot 4 (this moves your bots).
Vince Builds or other LAS addons are your friend.
One thing to always remember is that a single engineer must always run Bio Shell and if you are the only Engineer in the raid you will need to add tiers into Volatile Injection in order for it to have 100% uptime otherwise you will need to coordinate with the other Engineers in the raid to make sure you maintain proper uptime.
The builds below will have two missing amps since jabbithole has not updated how many amps you will now have at endgame. Also the last two LAS slots have been left empty to allow you to decide what is needed given the fight situation. If you want to do extra damage you can add in Unstable Anomaly to be cast inside the Bolt Caster GCD. If interrupts are needed on the fight you are able to grab OV, Zap, or Bruiserbot.
Note For Dungeons: You can make use of any of the below builds for dungeons. AoE Electrocute builds will be best on trash and multi-target fights, and Bolt Caster builds on single target. Bring T4 Zap and Obstruct Vision (tier down Artillerybot) in your utility slots and interrupt often.
Example Dungeon Build (base AMP/Ability Points) - Just add in T8 Electrocute or Bolt Caster as needed
Single Target
These are builds for single target fights. Bolt caster is the primary spender and bio shell and dashes are builders. In both builds there is room for extra utility skills as needed. If T4 Recursive matrix is required take tiers out of VI and Artillerybot. Urgent withdrawal, Diminisherbot and zap may also be removed for additional skills.
AoE
For AoE fights use Electrocute as a spender and either Bio Shell or Target Acquisition as a builder. When deciding on which build to use make sure all raid debuffs are already covered.
Single Target
The single target rotation begins with a double dash into an instant cast Bio Shell. Volatile Injection may be cast before the pull to start gaining volatility outside of combat, if not used then, cast to coincide with Innate. After casting the first Bio Shell begin spamming Bolt Caster. After reaching 30-40 Volatility, use Innate + Gadget and continue to spam Bolt Caster. Make sure to continue casting Volatile Injection, Quick Burst, Artillerybot, and Diminisherbot on cooldown. Use Bio Shell when its off cooldown, while between 30-70 volatility*. Throughout the rotation maintain “In the Zone” uptime by using dashes to generate volatility.
Notes: Bio Shell has a 0.5 second GCD and currently does more DPS then Bolt Caster so use Bio Shell as much as possible.
Due to Bolt Caster hits reducing the cooldown of Bio Shell, being strikethrough capped is extremely important. Lowering the cooldown of Bio Shell allows for less dashes in the rotation therefore increasing dps.
AoE
TA + MS
The AoE rotation begins with a half cast Target Acquisition followed by a Mortar Strike. Volatile Injection may be cast before the pull to start gaining volatility outside of combat, if not used then, cast to coincide with Innate. Immediately after Mortar Strike, use Innate + Gadget then spam Electrocute. TA + MS should be used during innate as innate counts as being in the zone. Make sure to continue casting Volatile Injection, Quick Burst, Artillerybot, and Diminisherbot on cooldown. Upon dropping below 30 volatility, recycle the opening rotation to maximise “In the Zone” uptime.
Bio Shell AoE
The AoE rotation begins with a double dash into an instant cast Bio Shell. Volatile Injection may be cast before the pull to start gaining volatility outside of combat, if not used then, cast to coincide with Innate. After casting the first Bio Shell immediately use Innate + Gadget and begin spamming Electrocute. Make sure to continue casting Volatile Injection, Quick Burst, Artillerybot, and Dmininisherbot on cool down. Use Bio Shell when its off cooldown while between 30-70 volatility*. Throughout the rotation maintain “In the Zone” uptime by using dashes to generate volatility.
Stat Priority
Strikethrough Till 17% > Multi-Hit Chance > Vigor > Critical Hit Severity > Critical Hit Chance
Why Stop at 17% Strikethrough?
- The highest Deflect Chance of any mob is 24.5%. in raid you should have -2.5% from True Strike and -5% from an Esper/Stalker meaning you only need 17% Strikethrough. Beyond this point Strikethrough is converted to Armor Pierce which is bad. Get as close as you can to 17% going a little bit over is far better than a little bit under though as getting deflected can upset your rotation
- Engineers get significant in-combat buffs to Multi-Hit Severity which pushes Multi-Hit Chance to the top of our list for Stat Priorities it provides the highest amount of output damage per rating than any other stat aside from strikethrough before cap.
Fusions
Weapon: Mordechai Redmoon's Ammunition (MRA performs better on single target and multi-target fights than Venom or Siphon)
Head: Barrage
Chest: Flurry
Hands: Shredder
Feet: Quick Feet
Rune Sets
Overview:
Striker: Our main rune set. Provides high amounts of Multi-Hit chance and Strikethrough chance.
Onslaught: Our best supplementary set. Provides much need Vigor and Strikethrough chance.
Eradication (Genetic Archives Class Set): A pretty strong set that allows our innate to do extra damage. The 4 set bonus provides us with much needed burst in AoE situations while the 8 set bonus just gives us a flat damage increase during our innate.
Technician (Datascape Class Set): This is the best class set for engineers. At the four set bonus it allows our bots abilitys to have a 10 second cooldown as well as allows them to be resummoned after one second if they are destroyed. The 8 set bonus just increasing bot damage by 20%. This set allows us to have a 10 second cooldown on an interrupt with Bruiserbot, as well as a shield heal from Repairbot. It helps provide us with great utility in raid and the obvious increased damage from our bots.
Ruthless (Augmentors Rune Set): Potent runeset that provides an additional damage proc on multihit for the four set bonus. While the eight set bonus provides a multihit buff to you and four nearby allies.
Tweaking your Rune Sets:
Strikethrough too high?
1. Exchange an Exceptional 120 Striker Strikethrough Rune with a Non-Exceptional 120 Striker Multi-Hit Rune
2. Swap Vigor with Strikethrough runes for your Eradication Set so that it has 2 Vigor Runes (1 Exceptional, 1 Non-Exceptional) and 1 Strikethrough Rune (Exceptional)
