Warcry is [Valkyr]’s subsumable ability. This ability is especially useful in Endo farming, due to its attack speed buff. As mentioned in the [Nekros] section of the guide, attack speed is useful because it helps them dismember body parts more easier for Desecrate. [Khora] should replace either her 1st or 2nd ability with Warcry. You can still use the normal [Khora] build, however you may consider using an alternative build with some priority on strength instead.

Venari:
Primed Animal Instinct, Tek Assault, [Medi-Pet Kit], [Fetch]

Arcanes:
Molt Efficiency gives you additional Ability Duration while Shields are active, highly recommended.
Magus Cloud is a mandatory operator arcane that increases your Void Sling radius. This lets you easily give your whole squad the Protective Sling buff.
Emergence Savior can be very useful to avoid operator “death” that causes a forced return to your warframe. This can be annoying and could potentially cause a team wipe or to ruin the enemy spawns.
Arcane Warmth prevents random cold procs from affecting you, which can be a pain when collecting endo since you need to pick it up with Fetch, rather than using Greedy Pull.

Archon Shards:
Crimson Archons Shard +10% (Tauforged +15%) Ability Duration - More Ability Duration is highly advised, less maintenance makes your runs more enjoyable.
Amber Archon Shard +100% (+150%) Effectiveness on Health Orbs - Increases the energy generated through equilibrium.
Amber Archon Shard +15% (+22.5%) Parkour Velocity - Recommended to help improve rollout speed. Noticable difference when using [Fetch] to grab the Health Orb.

Requirements & Notes if you want to cast Warcry as soon as possible (before enemies are killed)
Azure Archon Shard - Max energy in order to cast both Warcry and Strangledome from one health orb. 2 of these allows you to also set [Venari] to heal as well. Otherwise you won’t have enough energy to set [Venari] to heal after Warcry, so you’ll have to wait a few seconds to get energy back from Equilibrium, then set a target.
Amber Archon Shard - If you’re using [Fetch] Rollout you will need Health Orb Efficiency, so you can get enough energy to cast Warcry and Strangledome from one health orb.

To activate Molt [Vigor], use [Guardian] Shell (Vazarin 1) before you cast Warcry
[Nidus] and [Nekros] should both try to run [Power Donation], if possible. [Nidus] may ask you to run Enemy Radar instead of Steel Charge, to help compensate for his missing enemy radar.
