Archon Shards:

3x Tauforged Crimson Archon Shard (Duration)

with the 45% duration you get 200% duration. This reduces the health decrease of Shadows of the Dead to 1%

2x Tauforged Crimson Archon Shard (Strenght)

with the 30% additional strength we [Reach] 169% strength which leads to a 100% Armor strip (167% needed). Without this, [Corrosive Projection] is necessary for this, so you are free to choose the aura mod.

Abilitys:

Nourish (helmith)

with this Amount of Range and Duration:

50 sec buff duration and a radius of 62,5 metres to buff the group.

100 % Armor Strip (Optional mit Terrify)

As described above, with 2 large red shards we get the required value for a 100% Armor strip. Or alternatively, if these are not available, [Corrosive Projection] as an auro mod. If u Switch [Stretch] with [Creeping Terrify] there is an additional slow of 80% is added. However, the ability only affects 33 opponents at a time. And this in a radius of 30,75 metres. Take into account that the armour strip does not work on bosses.

Desicrate

50 sec duration and a radius of 62,5 m for extra loot. [Despoil] mod to conserve energy reserves as we only have 45% efficiency. Arcane Blessing gives us the resources for this and triggers Arcane [Guardian] constantly at the same time. [Equilibrium] to ensure that we are guaranteed not to run out of life and that the ability can be constantly active.

Shadows of the Dead

The 3 Arhcon Shards give us 200% stamina which, as described above, reduces the life loss of our shadows to 1%, allowing them to live for up to 100 seconds. The mod [Shield Of Shadows] is used to distribute the damage we would receive to the shadows so that we stay alive longer.

Secondary weapon:

I use 2 Augur mods here to replenish the shields, as I have no room for this in Warframe as I use all 3 ability mods.

Mod alternatives:

[Primed Sure Footed] instead of [Cunning Drift]:

[Primed Sure Footed] is a 400 day login reward. As long as you don't have this, you can use [Cunning Drift] to increase your range, or you can go for the normal [Sure Footed] instead.

[Primed Continuity] instead of [Archon Continuity]:

Prime [Continuity] requires less mod capacity with the same values for the build. the Archon variant does the same, however. the additional effect is irrelevant here.

Focus:

I use Zenurik for more energy due to its low efficiency.

To summarise:

The build is of course designed for looting. Nevertheless, it can strip 100% armour.

With the help of [Rolling Guard], [Shield Of Shadows], [Creeping Terrify], Arcane Blessing and Arcane [Guardian] we don't fall down directly when we take damage.

[Despoil] ensures that we don't permanently run out of energy at high range. [Equilibrium] also helps to maintain our life and energy.
