Acquisition[]
The mod can be bought from The Business for 20,000 Standing after reaching Rank 3 - Doer with Solaris United.

Notes[]
As noted above, the buff activates if the companion possesses over 1200 maximum shields through modding, and will remain active regardless of their actual moment-to-moment shield strength. However, the buff will temporarily deactivate if the companion is incapacitated.
Alternatively, as reloading restores up to 150 shields, maintaining companion’s shields (including overshield) over 1200 will activates the buff. Note that Battery Weapons won’t restore shields.
In order to get a 1200 maximum shield with the  Calculated Redirection mod at maximum rank, your companion will need a minimum 343 base shield. This can only be accomplished by the following companions:

You may opt to use  Link Redirection to reach the required shield values, but this is heavily dependent on your selected warframe's maximum shields: A warframe must have at least 960 maximum shields, either through modding or as is, to activate this mod.
Weapons that reload per shell, such as the  Strun, will generate overshields for each shell loaded in.
Bows and battery weapons cannot generate overshield.
As long as a Vulpaphyla's beast form reaches the 1200 shield threshold, the fire rate buff stays activated in their larval forms, even though the larvae don't have enough shields.
Bugs[]
When player is not the host it may not function at all, passive reloads may only work as host. Manually reloading or a companion dying & reviving may reactivate it, but its inconsistent.
