Equipment Variants

Relics

• Take Relic of Bava Nisos if you're having a hard time dealing with conditions.

Stats

• You could still play full Celestial, it makes the build more forgiving, but it also trades a lot of offensive stats for defensive ones you already have enough of.

Consumables

Food

• - defensive option with Explosive Entrance, Relic of Rivers and Thermal Release Valve synergy.
  • - budget version.

• - defensive ascended choice with passive damage mitigation while also providing a decent amount of offensive stats.

Utility

Usage

Amalgam basics

• Engineers with the Amalgam elite specialization lose access to most of their regular toolbelt skills. Amalgam toolbelt skills are fully customizeable with their own set of skills, acting like a second utility bar.
  • Your healing skill is exempt from this rule, as it retains its regular toolbelt skill.
  • The elite toolbelt slot is always Evolve, but you get to customize this skill through traits.

• Much of the specialization revolves around Evolve. Your selection of toolbelt skills directly impacts Evolve, as Evolve gains bonuses on activation based on what toolbelt skills you're running.

General

• Evolve is always useful as it can be used for both defense and offense. On this build Evolve grants a passive stat boost, Alacrity for CD recovery, Quickness for faster casts, Resistance to help you ignore conditons that'd lower your damage like Blind and Weakness or ones that'd hinder your escape like Chill and Immobilize, and barrier for general tankiness.
  • Evolve has 2 charges.

Damage

• Offensive Protocol: Shred and Electric Artillery apply Immobilize which you can use to root people into your harder hitting skills like Devastator.

• Spear has a central mechanic called focus. Focused targets are more heavily affected by your Spear skills.

• You make someone your focus target by hitting them with Conduit Surge. Using this as your opener is therefore recommended.

• Skill #3 Lightning Rod should be activated as soon as you use Conduit Surge. It's an instant skill that does damage passively around you and being charging up its chain skill.
  • Charging it up turns this skill into Electric Artillery, a long range strike with Immobilize, making it great at setting up burst.

• Roiling Skies is primarily a setup skill too as it's a CC with not much else to it.

• Devastator is your primary burst skill on Spear. Try to land it on focused targets, preferably when they're CC'd so it doesn't miss.

• Spam grenades when your Spear skill are on CC or if getting into melee would be too dangerous. Fill any downtime with grande spam, even if it's just the autoattack.

• Grenade Kit skills ranked from most to least threatening:
  • Shrapnel Grenade. Simple fire and forget skill with great damage.
  • Poison Grenade and Freeze Grenade. Poison Grenade does more damage over time and it's unblockable, which is important because you can even use it to score healing reduction on skills like Revenant's Crystal Hibernation, but Freeze Grenade does more damage upfront so it's better for bursts.
  • Flash Grenade barely does any damage and is mostly a defensive tool that Blinds enemies, but it's still good for condi variety and proccing traits too.

• Even your healing skill is a minor source of burst damage in melee range:
  • Mitotic State a lesser Grenade Barrage around you from trait. This is quite useful for counterpressuring targets, sometimes even turning the tides against the one chasing you. Be warned though that the grenade proc could also end up accidentally breaking your Stealth when you heal next to an enemy, which could actually endanger you on low health. While the build doesn't have stealth access by default, you could still get it from allies and combo fields, so it's worth keeping in mind.

Sustain

• Every stance skill cleanses 1 condition, Evolve cleanses 2.

• Gaseous State removes all movement-impairing conditions and makes you immune to them for a few seconds. If you're under heavy condition pressure it might be worth opening with this skill - doing so increases the chance of you removing damaging conditions with your other skills.
  • This is one of your stunbreaks so there's a risk attached to using it for cleansing alone, but as long as you have your other stun break ready, it should be fine.

• Coincidentally your other stunbreak Defensive Protocol: Cleanse is also a source of condi removal and can be used in a similar fashion. DP:C removes both damaging and non-damaging conditions.

• Every toolbelt skills grants barrier, which is useful against any form of pressure.

• Your healing skill Mitotic State heals you over time, and this healing can be increased by maintaining barrier on yourself. Combining it with toolbelt skills is highly recommended. Some of these skills are instant so you can apply barrier whenever you want.

• One of these instant defensive skills is the toolbelt of your heal, Symbiotic Shielding. The best part about this however is the Shocking Aura application - you can grant yourself this aura even while stunned, which in turn stuns attackers.

• Liquid State can be used for evasion and Defensive Protocol: Protect to save endurance or if you can't dodge.
  • Both of these skills can be used while immobilized.
