Mag's passive works while solo, broken while host or client.

[(PSN)Nerocompany]

Mags passive while solo is vacuum in ~8 meters of range radius around her, in multiplayer while client or host, It does not work. Instead being the innate ~3 meter universal vacuum every warframe has. 

In solo it also immediately stops working upon the death of a sentinel or pet wether or not the companion had vacuum or fetch equipped.

It has been this way since the passive change on the launch of veilbreaker
