    Celestial Mechanist Open World Build

    By Jen28 February, 2022Updated:22 February, 202528 Comments2 Mins Read Open World Builds

    GW2. Best Open World Build. Celestial Mechanist Open World. Engineer PvE.


    • Boon for group events: Alacrity

    The Celestial Mechanist for Open World is an engineer build that is simple and has a Jade Mech pet to boost apply boons and to protect you while you apply burning from the Spear and Flamethrower.

    The Shift Signet passively copies all boons you gain to your Jade Mech, which means it will also gain plenty of Might and Quickness from the tool belt abilities. However, the passive is lost when activating Shift Signet, so only use this in an emergency. Likewise, the Overclock Signet can be used for extra damage, but in dangerous situations, it should be saved to revive the Mech.

    Applying Barrier gives Alacrity which lowers the cooldowns of the already fast-recharging and high damage Spear abilities. Always use your Mech abilities and Barrier Signet to upkeep this Alacrity. When Spear skills are on cooldown, swap to Flamethrower before swapping back to Spear.

    Skill Priority

    • F1/F2/F3 + Barrier Signet
    • Spear 2 > 3 > 5
    • Flamethrower 4 > 2 > 3

    Try to recast the second activation of the Spear 3 after several seconds of casting the first. To do this you can’t stay in Flamethrower for long.

    NOTE: Automatically cast your Mech abilities by CTRL + Right-Clicking the F1-3

      I feel like this build is pretty squishy with all Zerker, even with the Golem and Mech I feel like I’m running for my life most of the time annd going down quickly when soloing harder Elites and stuff. I don’t think this is quite the sweet spot for a solo open world build.

        You can always adapt the build to your needs, if you feel squishy then you take some pieces with toughness, thats how it works.

        In this case i would prefer use the mace/pistol, still give a lot of damage and mace gives some shield, vigor and regen.

      Isn’t the idea behind the playstyle for this particular build to have the mobs on your rune golem, while your mech unloads, and you go through your rotation?

      Hey, great guide! 😀 It feels nice to play a berserker build and to be able to dish out great damage while still keeping a safe distance from the enemy. But I still have one question: What ability should I use while waiting for my cooldowns, should I spam rifle 1 or exclusively camp grenade kit and spam grenade kit 1 while limiting my rifle use to the 2-5 skills?

      Reply
      • Vallun on 25 April, 2022 12:39 am

        Rifle 1 does less damage than grenades, but is more reliable. Generally use all of your 2-5 on grenades and then stick to rifle, but keep using the grenade auto attack if you need to kite while attacking.

      I played 4 variations of Mech pve builds:

      Solo Survival Celestial, Sanctuary Runes Alac Flamethrower
      Group Ritualist, Alac (Mace/Pistol) (Might change to healing instead of condi dps)
      Condi DPS, Viper with Explosions
      This build

      I found this Build to be very, very squishy and 1/2 of the dps of the Condi build and it is also a little bit harder since grenades are not auto attack (and are slow without Grenade Barrage).

      What really turned me off for the rifle is that the most damaging skills require you to be close to the target.

      Reply
      • Vallun on 25 April, 2022 12:37 am

        Did you just cherry pick the weaknesses of the build without affording its advantages? It has range unlike the condi viper build which means you can be much safer positioning. If you want to auto attack in melee range, then yes this build is bad. However, if you want to easily hit targets from range, this one works best in my opinion.

      Why is the power wrench trait taken in this assembly? It reduces the cooldown of skills in a “tool kit” that is not used in this build.

      Reply
      • Jen on 24 May, 2022 7:32 am

        The trait not only does that, it also reduces the cooldown of the elite skill when you dodge, I know sometimes the tooltips are confusing but read them paying attention to understand the synergy. The other options in the slot aren’t worth anyway.

      A friend of mine started few weeks ago and just used his Lv80 booster and received a full Celestial gear. Are the Traveler runes a good alternative or what Boon Duration would you recommend to use until he got Leadership?

      Reply
      • Vallun on 4 February, 2023 3:05 pm

        the movement speed would be wasted, try krait or elementalist runes for now unless you really wanted more boon duration then traveler is fine

        Reply
        • Jimmy Spellman on 5 February, 2023 10:16 am

          I bought him Elementalist runes because he reach 100% burning & bleeding duration anyways and the build turns out to be pretty solid. Thanks for the advice buddy, have a great day!

      Is there an actual link to the build used in the celestial mechanist video? It just points back here even though its a different build.

        It is the same build

      Can you go pistol+pistol or do you lose much dps/surviability by going that?

        You can

      Hi, thanks for all the awesome content ! I’m wondering how does the shortbow alternative work with Akeem and Celestial, since shortbow does not provide confusion and inhate condition on weapon skills ? Thanks in advance 🙂

      Reply
      • Jen on 14 May, 2024 3:43 pm

        You can’t, the shortbow is just optional weapon in case you need AoE for like group events or tagging, and to get Corruption stacks, the build is just based on mace/pistol.

          Oh okay. Thank you for the quick answer !

      I love the build so much, brought back my engineer appreciation! What other relic would you suggest using from the Relic Chest if one has no access to Akeem yet?

      The skills and traits tab show two different builds. Which one is up to date?

      Hey GuildJen,
      It looks like this page might need some updating. I believe this build is suppose to be utilizing a Spear (If you hover over the weapon it shows the spear) but it says Short Bow beside the weapon.

      It’s a little confusing.

      Reply
      • Vallun on 16 September, 2024 5:43 pm

        yes sorry this may have occurred during a live edit, should work now if you refresh

    13. Homie on 19 September, 2024 12:17 pm

      Would there be any downside to using the togo gear set with this current spear build? Would togo be a dps increase over celestial?

      Reply
    14. Twboy on 8 October, 2024 8:08 am

      Why the build is using short bow with Superior Sigil of Strength and cleansing?

      Hi, I’m thinking of using celestial mechanist in WvW and Open World, but they use different Runes, in the builds you make available on the site, I wanted to know which rune would be best to use in the 2 modes, Rune of the Trapper, Leadership or Divinity?

      Reply
      • Jen on 20 March, 2025 1:37 am

        Leadership rune will be the best balance between them.
