The Quills daily standing cap at Mastery Rank 12 in Warframe is 13,000 standing per day.

How the Quills standing cap works

For Quills (and most syndicates), the daily cap scales with your Mastery Rank using this formula:
Daily cap=1,000+1,000×MR\text{Daily cap}=1,000+1,000\times \text{MR}Daily cap=1,000+1,000×MR.

So at MR 12:

  • Base: 1,000 standing.
  • Plus: 12 × 1,000 = 12,000 standing.
  • Total: 13,000 Quills standing per day at MR 12.

This applies to Quills because they follow the same syndicate cap system discussed in community posts and wiki Q&A about Quills standing.

Quick scoop: what this means for you

  • At MR 12, you can turn in Sentient Cores (from Eidolons and other Sentients) up to a total of 13,000 Quills standing per reset.
  • If you farm more cores than that in one day, you’ll need to wait for the next daily reset to hand in the rest, which is why many players complain about the cap when doing multiple Eidolon nights in a row.

In forum discussions, players often describe hitting the Quills cap after just a few Eidolon runs and then having to sit on excess cores for several days.

Mini FAQ

Is the Quills cap different from other syndicates?

  • No, community Q&A confirms Quills use the same MR-based formula as standard syndicates: MR × 1,000 + 1,000.

Does raising MR increase the Quills cap?

  • Yes, every Mastery Rank adds another 1,000 to your Quills daily cap, so pushing MR is an indirect way to raise how many cores you can cash in per day.

TL;DR: At MR 12 your Quills daily standing cap is 13,000 ; it’s calculated as 1,000+1,000×121,000+1,000\times 121,000+1,000×12, same system as other syndicates.
