Standing

Standing is a special resource central to the Syndicates mechanic, which indicates a Tenno's favor with a particular syndicate. Players can begin earning Standing once they have achieved Mastery Rank 3.

Earning Standing with a syndicate is largely a matter of wearing that syndicate's Sigils, a cosmetic item received from Syndicates. To equip a Sigil, the player must go to the Regalia section of the Appearance tab in the Arsenal, select the location of the Sigil (Front or Back of the Warframe), and then select the desired Sigil. When wearing a syndicate's Sigil, approximately 2.6% of any affinity earned will be converted to Standing with that syndicate. Higher tiered Sigils also grant a multiplier to Standing gain depending on the Sigil's rank, ranging from +5% to +15%.

Standing be used to purchase their respective Syndicates offerings with that syndicate, essentially trading on favors that the Tenno has performed for that syndicate. Syndicate offerings are gated by rank within the syndicate, and syndicate rank is gained by achieving certain amounts of Standing. In essence, a Tenno can choose to spend earned Standing on lower-tier offerings, or save up Standing to gain access to higher-tier offerings.

Standing gain has a daily cap that players cannot exceed, which determines the maximum amount of Standing they can earn daily. This amount is calculated as 1000 * Mastery Rank + 1000 per day.
 * A player with Mastery Rank 18 would be able to gain a maximum of 1000 * 18 + 1000 = 19000 Standing in one day (+ 9500 for the associated allied Syndicate).
 * The reward Standing from Syndicate Alerts do not affect or count towards the daily Standing cap however.
 * Playing a Syndicate Alert with a reward of 1,600 and wearing the highest Sigil (+15%), will reward 1,840 reward Standing (+920 for allied) and will not be subtracted from the daily cap limit. All other standing received with the primary Syndicate in this mission for killing, completing challenges etc. will be subtracted from the cap.
 * Syndicate Medallions do not count against the daily cap, thus they can provide additional Standing even if the cap has been reached.
 * An Affinity Booster would, in effect, double Standing gained since Standing is based on affinity earned.
