Weapons Platform [Ember] for general steel path and endurance mainly focusing on [Fireball Frenzy] to boost weapon DPS, passive to boost strength to boost [Fireball Frenzy] and nourish further, and [Healing Flame] for easy survivability as well as nourish + [Exothermic] for energy economy.

UPDATE 2025
Arcane Truculence is a nice option that can create 30m viral procs everytime you gain overguard via [Healing Flame]

Update June 2024
[Healing Flame] now gives overguard which makes you status immune while overguard is active and clears existing statuses on cast. Overguard also gives you 0.5s i-frames on breaking, meaning every cast of fireblast can generate approximately 1.5s of i-frames (about 1s from shield gate and 0.5s from overguard). This effectively allows [Healing Flame] to replace [Catalyzing Shields], [Rolling Guard] and [Primed Sure Footed].

PLAYSTYLE

1. Cast 4 to set enemies on fire, proccing [Ember]'s passive strength buff, dealing minor DoT and minor crowd control and also increase energy orb drops
2. Once the maximum number of enemies are on fire, hold 1 to give heat buff from [Fireball Frenzy] (and optionally a buff like Nourish subsumed over 2).
3. Spam fireblast whenever overguard goes down to regain overguard and partially strip armor
4. Use a good weapon to kill stuff

BUILD SPECIFICS

Duration
Duration helps up keep of [Fireball Frenzy] and nourish

Efficiency
Nourish with [Exothermic] OR [Equilibrium] can sustain energy particularly if the only thing you are really casting is Fireblast. If you have energy issues still consider just dropping [Blind Rage] for [Transient Fortitude] or [Umbral Intensify].

Range
Positive range helps fireblast radius so you get overguard easier

Strength
Strength boosts [Fireball Frenzy] heat bonus and nourish bonus. [Ember]'s passive also gives free 5% strength for each burning enemy (for example, hitting 20 enemies with inferno and setting them on fire gives the next immediate cast of inferno a bonus 100% strength).

Flex/alternative options

• [Exothermic]: [Exothermic] can make energy orbs independently of your companion and eximus spawns. [Equilibrium] is flexible for this as it can actually generate even more energy particularly when paired with synth deconstruct on a companion and eximus kills.
• [Augur Message]: interchangeable with [Augur Secrets] or [Umbral Intensify] for more strength, [Rolling Guard] for more backup survivability

ARCHON SHARDS

1 Amber Cast Speed
1 to 2 Amber Energy Orb Effectiveness shards (OPTIONAL) : allows for more consistent energy regeration while using Exothermic. Don't use this if you prefer equilibrium.
Rest are flex and can go into :

• Topaz Secondary Crit Chance shards, which give +75% cc when you kill enemies affected by heat status, which ember can consistently cause.
• Parkour velocity for mobility

ARCANES

Arcane Hotshot - free 300% crit chance
Arcane Truculence - max viral procs in 30m on overguard gain
Arcane Energize - optional for max energy economy taking advantage of all the energy orb drops.
Arcane Eruption - funny choice that causes huge area of 30m knockdown everytime you pick up an energy orb, which is constantly generated by [Exothermic]. This basically keeps the entire map knocked down, except for eximus units. Note, this can drastically slow down defense and survival missions in public so don't always equip this.
Molt Augmented - bonus 60% strength
Molt Efficiency - free duration

HELMINTH OPTIONS

For Endurance, subsume over 2 since you don't need damage reduction and inferno DPS doesn't scale regardless.

• Nourish - gives free viral and boosts energy return
• Roar - boosts weapon damage and inferno damage, with double dipping on heat DoTs
• Sickening Pulse - doubles heat DoT damage
• Breach Surge - after full strip breach surge sparks deal much more damage and can be triggered by inferno DoTs
• Condemn - great crowd control, lets you drop brief respite: https://overframe.gg/build/292574/ember-prime/condemned-in-hellfire-crowd-control-steel-path-ember/
• Gloom - great crowd control, needs slight adjustments: https://overframe.gg/build/229524/ember-prime/the-slow-cooker-gloom-ember/
