So, this is my shot at a "Meta" [Caliban] build.

IMPORTANT NOTE: It has been confirmed that [Caliban]'s Passive and [Adaptation] do not stack. If you equip [Adaptation], you will gain the higher of the two resistances, effectively losing you [Caliban]'s passive on yourself. For this reason, in my [Caliban] builds, I prefer to treat his passive as a free Adaptation that takes up no mod space, that is why it is not on this build.

My Venato Build to go with this: https://overframe.gg/build/258984/

Those of you who are here from my other Caliban Build, https://overframe.gg/build/258784/caliban/caliban-conculyst-summoner/ , This build is not based entirely around Lethal Progeny, although they are still very viable. This build is based around synergy from all abilities, as well as being played on Longer missions like Survivals, Defenses, Interceptions, etc. This build also makes sure to use only fully ranked mods, for ease.
Lets begin.

To start off with, our Ability Strength Mods. [Growing Power], [Umbral Intensify], [Transient Fortitude], Molt Augmented. These mods add up to a total of 294% Ability Strength. The reason this number is important is because you need 287% ability strength to gain 100% bonus damage on your 2, Sentient Wrath. With Veilbreaker, we now have the ability to get this without using [Blind Rage], meaning this build no longer needs [Primed Flow].

We still use [Streamline], since it allows us to cast our abilities as we want.

We have [Narrow Minded], [Augur Message] and [Primed Continuity] for Ability Duration, getting us to a healthy 250%, and [Stretch] as well as [Cunning Drift] to counteract the Range down from [Narrow Minded].

Our Helminth now, as of Abyss of [Dagath] is Roar! With the buffs to shields and shield gating, we no longer need Resonator to survive in Steel Path and above missions! Now, we can use roar to buff our own damage as well as the damage of our Conculysts! [Caliban] is finally playable at a high level without cheese and it's been a wonderful breath of fresh air into his kit!

Because we have over 200% Strength, Fusion Strike will also strip all armor and shields from enemies!

Finally, our second Arcane is Arcane Energize for energy.

How to play this build? Roar will buff your summons, causing them to deal a good amount of damage to everything around them. While that's happening, [Caliban] can maintain a solid shield defense using his passive and the shield gained from his summons, leading to a very versatile frame that can do any type of content. Span 2 for damage increases, and 4 for armor strip.

UPDATE VEILBREAKER:

Use Archon Shards on this Warframe for Armor if you have Azures, or Duration if you have Crimsons.
