Overview

Condition mechanist is a strong and versatile DPS build that is both a strong and simple version of condi engineer. The addition of the mech ensures reliable damage with minimal input, and the strength of signets allows you to replace kits and vastly simplify the rotation as you desire.

The plethora of viable builds means that this is a strong option regardless of experience level, and it allows you to gently increase the difficulty (and damage) as you gain confidence.

Skill Bar

Spear

Utility

Pistol Variants

Players who don't own Janthir Wilds cannot use spear, so Pistol/Pistol is the next best option. Pistols also have better ranged capabilities, which might be preferable on some encounters.

• Ideally, when running Pistol/Pistol you replace Grenade Kit with Bomb Kit.

Skill Variants

• The heal skill can be whatever you want, though some options stand out:
  • Rectifier Signet is very potent with Mech Core: J-Drive as it has higher passive healing, which isn't lost upon activating the signet.
  • A.E.D. allows you to survive some one-shot attacks.
  • Healing Turret does an AoE condi cleanse when it is placed, which can be situationally useful.
• The highest damage option is to replace Superconducting Signet with Flamethrower, though the additional complexity means this may not be better in real encounters.
• If you want to totally avoid kits, use Force Signet. Be aware that removing Grenade Kit removes your main way of triggering both Aim-Assisted Rocket and Shrapnel, which means Explosive Temper and Big Boomer should perform better, though the difference will be minor.

Relic

• Either sigil could be swapped for a Sigil of Superior Sigil of Geomancy. The sigil is cheaper than Sigil of Superior Sigil of Bursting and the damage is slightly better than Sigil of Superior Sigil of Earth, but it requires you to be in melee to benefit and variance in your kit swaps can reduce its DPS.
• The recommended setup is practically the same damage as full Viper stats gear.
  • In this case, would be the stronger utility.

Non-SotO Relics

There are two options for core relics. Relic of Thorns has the highest potential, but it isn't triggered reliably on every encounter. Relic of the Aristocracy works everywhere, but requires modifying your gear as follows:

• You would want to swap some pieces to Sinister stats such that you reach ~67% base condition duration, with bleeding and burning duration capped.
• It may be recommended to pick an option that offers some utility instead.

Usage

Simpler Spear Rotation

Mechanist's signets are very strong, which allows them to replace Grenade Kit.

With this rotation all you need to do is use the following skills off cooldown:

• Conduit Surge
• Lightning Rod/Electric Artillery
• Devastator
• Overclock Signet - skip if there's any danger of your mech dying, so you can use it to resummon them instead.
• Your mech skills

Spear rotation

The basic structure of Spear's rotation will be very familiar to players of engineer: You finish your auto chains and use DPS skills off cooldown until you use Conduit Surge (skill 2), then jump into Grenade Kit and use Shrapnel Grenade along with Freeze Grenade and Poison Grenade if they are off cooldown.

The unique aspect of Spear is the Focused mechanic, which is applied by Conduit Surge and refreshed by the last hit of the auto chain. You can only have a single Focused target, and hitting the target with Spear skills will trigger enhanced effects:

• The autoattack chain will apply Vulnerability
• Conduit Surge applies more Burning
• Lightning Rod ⇒ Electric Artillery deals more damage, and applies more Vulnerability and Burning.
• Roiling Skies deals (slightly) more CC.
• Devastator will hit the Focused target with Focused Devastation, applying more damage and Burning.

Rotation fundamentals

Your three biggest damage contributions come from Lightning Rod ⇒ Electric Artillery, Conduit Surge and Shrapnel Grenade. When you activate Lightning Rod a whirling AoE spins around you for four seconds, gaining a charge for each target hit. After this Electric Artillery will activate and do damage according to its charge. The cooldown for the skill begins once you activate Lightning Rod so using this skill is high priority, while you can afford to delay Electric Artillery if needed (it lasts until Lightning Rod is ready again).

Conduit Surge and Shrapnel Grenade have the same cooldown, so every time you use Conduit Surge you can immediately jump into Grenade Kit and use Shrapnel Grenade. These two skills form the backbone of your rotation.

You can swap out of Grenade Kit either by pressing Grenade Kit again or by weapon swapping. Using weapon swap will cancel animations when used, which could result in cancelling a grenade skill before its finished. Using Grenade Kit a second time to leave the kit avoids this issue, but if you're only casting a single grenade skill (which is often the case) then the cooldown on kit swaps won't have ended when you need to leave. Ideally you should practise both methods.

Example Opener

1. Lightning Rod
2. Conduit Surge
3. Grenade Kit
   1. Shrapnel Grenade
   2. Poison Grenade
   3. Freeze Grenade
   4. Weapon Swap
4. Devastator
5. Electric Artillery
6. Conduit Surge
7. Grenade Kit ⇒ Shrapnel Grenade ⇒ Weapon Swap

For the rest of the rotation, try to finish your auto chains (Conduit Surge and Lightning Rod take priority over finishing the chain), while using the following skills off cooldown:

• Lightning Rod/Electric Artillery
• Devastator
• Freeze Grenade
• Poison Grenade
• Your mech skills
• Overclock Signet - skip if there's any danger of your mech dying, so you can use it to resummon them instead.

You can look at the cooldown of Freeze Grenade and Poison Grenade whenever you go into Grenade Kit for Shrapnel Grenade. If the cooldown is under two seconds, you exit, do an auto chain, then go back into Grenade Kit for them.

Your two main skills have an effective cooldown of just under five seconds (with Quickness and Alacrity). However, Lightning Rod/Electric Artillery has an effective cooldown of just over 10 seconds, and your other grenade skills and Devastator have a ~16s cooldown (with Alacrity). This means that played optimally, these skills will end up shifting their position relative to each other over the course of the rotation.

Video example

You can simplify the rotation slightly if you slightly delay Conduit Surge until after Lightning Rod/Electric Artillery. As you always want to be following up Conduit Surge with Shrapnel Grenade, your rotation should end up always casting these three skills together (alternating between Lightning Rod and Electric Artillery).

Additionally, if you find handling kits tricky (or just prefer a neater loop), you can use the following rotation, which is a relatively small DPS loss over the optimal one:

Burst Loop

1. Lightning Rod
2. Conduit Surge
3. Grenade Kit
   1. Shrapnel Grenade
   2. Poison Grenade
   3. Freeze Grenade
   4. Weapon Swap
4. Devastator

Filler Loops

Repeat this loop three times, then return to the Burst Loop

1. Electric Artillery or Lightning Rod (whichever is available)
2. Conduit Surge
3. Grenade Kit
   1. Shrapnel Grenade
   2. Weapon Swap
4. Puncturing Jab ⇒ Rending Strike ⇒ Amplifying Slice x2

This rotation slightly delays using Devastator to make the rotation loop properly. It also does not list mech skills or Overclock Signet, which should be used off cooldown but have no cast time. You could set the mech skills to autocast, though this may be less effective than triggering them yourself.

Flamethrower Spear Rotation

Example Opener

1. Lightning Rod
2. Conduit Surge
3. Grenade Kit
4. Shrapnel Grenade
5. Poison Grenade
6. Flamethrower
7. Stoke the Flames
8. Flame Blast
9. Weapon Swap
10. Devastator
11. Electric Artillery
12. Conduit Surge
13. Grenade Kit
14. Shrapnel Grenade
15. Flamethrower
16. Napalm
17. Flame Blast
18. Air Blast
19. Weapon Swap

• This rotation follows the same principals as the rotation above with the addition of Flamethrower skills. All are important damage contributors except for Air Blast which can be saved for CC.
• As Stoke the Flames has the same cooldown as Poison Grenade, it's helpful to follow up with a switch to Flamethrower each time you use it.
  • Ideally Flame Blast should also be available every time, and you can get two additional uses in between each Stoke the Flames.
• As with Grenade Kit, it's helpful to look at cooldowns every time you're in Flamethrower so you have an idea of when to enter it next.

Video example

Pistol Rotation

Although Pistol offers much better ranged damage, it still wants to use Bomb Kit, which requires you to be in melee. For a truly ranged build, you can use Grenade Kit instead and use in the same way, though the damage is lower. In addition, Shrapnel Grenade has a lower cooldown than any pistol skill, so optimal use would require tracking it independently and using Grenade Kit more often. Cast Freeze Grenade/Poison Grenade together with Glue Shot and you can use the latter skill to track those at least.

Opener

1. Static Shot
2. Blowtorch
3. Poison Dart Volley
4. Bomb Kit
   1. Fire Bomb
   2. Galvanic Bomb
   3. Big Ol' Bomb
   4. Weapon Swap
5. Glue Shot

For the rest of the rotation, autoattack and use mech and pistol skills off cooldown. After using Poison Dart Volley, go into Bomb Kit and use Fire Bomb as well as Galvanic Bomb and Big Ol' Bomb if they're available. You should also use Overclock Signet off cooldown, but skip if there's any danger of your mech dying, so you can use it to resummon them instead.

In addition to Poison Dart Volley and Fire Bomb having the same cooldown, so do Glue Shot and Big Ol' Bomb, so for a bit of extra damage you can cast these skills together and use the cooldown of Glue Shot to track when Big Ol' Bomb is ready.

General Tips

• Make sure you're within 360 units of your mech before using F1-3 skills, or they will have a 20% longer cooldown thanks to Mechanical Genius.
• You can swap to Kits during the cast of skills without interrupting the skill.
• Press all your mech skills off cooldown - you can save Jade Mortar for CC if necessary.
• If using Overclock Signet, use it off cooldown. It is a very small DPS gain though, so hold on to it if there is any danger that the mech might die.

Crowd Control

• Roiling Skies: 200 defiance break - 232 to your Focused target
• Sky Circus: 232 defiance break - used for damage in your rotation, but the damage is low so you could hold onto it for CC
• Jade Mortar: 100 defiance break - the damage is high and the CC is low, so it's not usually worth holding on to for CC
• Superconducting Signet: Not a CC in itself, but it drops a lightning field that you could combo with Conduit Surge for 100 defiance break.
