[ariivanasan]

hi. i have i Question about affinity focus farming.
From the wiki 
 

Quote

Companions gain their own Affinity, similar to Tenno.

so.. when i want to farm xp for warframe\weapons i can take with me my Companions and get same amount of xp. But what about focus and Companions?  if i take Companions with me, how much focus xp i get? less or same?

Affinity and Focus gains are directly related, if your Affinity isn't affected then neither are your Focus gains.

You will only lose out on Affinity-and-thus-Focus if your Companion kills something.
