INTRODUCTION

Cook your enemies to tenderness with a slow simmer. Take advantage of Ember's passive to reach maximum slow from Gloom and take advantage of the extreme slow to make knockdown/stagger animations from [Ember]'s abilities last forever. The augment [Exothermic] is an optional addition to increase the rate of energy orb drop to help sustain the drain of having two chanelling abilities.

UPDATE 2025
Arcane Truculence can go over Arcane Energize as generating overguard via [Healing Flame] can create 30m viral procs

UPDATE June 2024
[Healing Flame] is receiving a slight buff, giving overguard on overheal, which gives knockdown and status immunity as well as extra 0.5s overguard gate.

BUILD SPECIFICS

Duration
We will have to [Sacrifice] duration as it is the least important stat as 3 is not affected by duration and 4 has a reasonably long base duration, with 10s at 67%. The drain on 1 and 2 chanelling abilities can be mostly offset by high efficiency and energy [Regen] methods.

Efficiency
While max efficiency of 190% is ideal to minimise the drain of 1 and 2, having 160% efficiency is a reasonable alternative if you can generate energy orbs consistently using [Exothermic] and pair this with arcane energize and [Primed Flow]. You can also use a companion with [Seismic Bond] to gain a free 30% efficiency to hit the 190% cap from 160%. With a drop rate of 15%, roughly every 7 enemies killed should drop an energy orb. If you find this is ineffective for you or don't own arcane energize, it is reasonable to switch Exothermic or Primed Flow out for streamline to hit the efficiency cap.

Range
A range of 145-175% gives decent range to 1,2 and 3. Ideally this would be even higher. [Overextended] drops the strength too heavily and makes gloom range a bit too high.

Strength
To hit the 95% slow cap, you need to activate gloom at 272% ability strength. This can be achieved by taking advantage of [Ember]'s strength passive, where she gains 5% strength for each enemy on fire in a 50m radius. That means you need to kill 250 enemies to activate Molt Augmented to max 60%, then set about 12 enemies on fire before activating Gloom to [Reach] the cap. Alternatively before molt augmented, you would need to set 24 enemies on fire. This should be reasonably easy to do on steel path with Grineer by casting 3 or 4 but may be slightly harder on squishier targets like infested or in low levels as the enemies will die before you hit a high enough bonus strength (check your HUD indicator). You can reduce the strength gap by using future external str boosts eg Madurai, Zenurik, [Grimoire] etc.

Flexible slots
The aura, exilus, [Exothermic] augment and [Catalyzing Shields] are all flexible slots that can be changed depending on your playstyle.
If you are playing lower levels and do not like shield gating, you can switch out [Catalyzing Shields] and [Brief Respite] for [Growing Power] and [Adaptation].
If you do not own [Primed Sure Footed], use handspring, vigilante armaments, power drift or preparation
Exothermic can be swapped for streamline (ideal) or augur reach/secrets depending on your prefernece.

[Archon Vitality]
[Archon Vitality] is optional since [Ember]'s abilities don't really deal alot of damage that would make them worth buffing. Her 4 is primarily used to nuke low levels, produce energy orbs and set enemies on fire. If you really want to boost heat DoTs, you can swap [Catalyzing Shields] out for it.

Arcanes
Energize is nearly compulsory to maintain energy, particularly in a pinch.
Aegis for second safety net
Eruption is a fun but unnecessary form of additional crowd control

Archon Shards
Very flexible:

• 1 amber cast speed
• 2 or more Energy orb effectiveness means you can drop Arcane Energize
• 2 or more Energy max shards allows you to drop [Primed Flow]

SURVIVABILITY

Option 1: Shield gating for SP endurance
[Catalyzing Shields] drops max shields to 93. Casting Fireblast costs 30 energy, which generates exactly 93 shield with [Brief Respite] and FOUR augur mods (i.e. two on frame and two on pistol), giving the full 1.33s shield gate. [Rolling Guard] is optional. Gloom provides crowd control which slows enemies down reducing the chances of you taking damage.

Option 2: Casual Tanking
[Ember] can get up to 90% damage reduction at full heat. Swap [Catalyzing Shields] for [Adaptation], [Augur Reach] for [Archon Vitality], Molt Augmented for Arcane [Guardian] and [Brief Respite] for [Growing Power], [Corrosive Projection] or [Mecha Empowered]. [Mecha Pulse] is also optional over [Augur Reach] if running a kubrow.

PLAYSTYLE

1. Use an energy pad or zenurik to gain an initial energy pool when starting the mission for safety
2. Activate both gloom and immolation
3. Cast 4 into crowds and kill people to generate orbs to quickly fill up the remainder of your energy and build heat meter
4. Cast 3 or 4 into a dense crowd until you see at least 75% ability strength on your passive, then quickly deactivate and reactivate Gloom to 'snaplock' the 272% strength needed for 95% slow.
5. Play like normal ember, using 3 when at max heat meter to full strip armor and reduce heat meter, and alternating with 4 to kill enemies/generate orbs and generate heat meter.
6. Walk around the map and watch the world burn in slow motion

ARSENAL

WEAPONS
AOE weapons that can spread heat procs synergize well by boosting [Ember]'s ability strength from the passive, although this may not be entirely necessary since 3 and 4 abilities already do this.

Good weapons with decent heat and status chance include:

• Ignis Wraith: https://overframe.gg/build/235289/
• Kuva Ogris with nightwatch napalm augment : https://overframe.gg/build/235322/

Here is a sample video showing the extreme slow and near-permanent stun from fireblast, as well as the easy energy management:

COMPANIONS
Use [Nautilus] for grouping, which will improve inferno overlapping rings. Equip [Seismic Bond] for free 30% efficiency while channelling either gloom or immolation, meaning you can drop [Fleeting Expertise] rank 5 to rank 4.
