Command An Army Summons: Banner Odds, Pity & Costs

Summoning happens at the banner in the lobby, and Gems come from codes, quests and match wins (see how to get Gems). Owning a unit is not the same as fielding it: it still has to fit inside your star limit.

How to spend Gems

Summons FAQ

Is there pity in Command An Army?

Yes, the banner has a 4-star pity counter. The one number posted so far is a player at 342/400, so the guaranteed 4-star appears to land at 400 summons (20,000 Gems). Treat 400 as one report until more players confirm it.

Should I do single pulls or ten pulls?

It costs the same: 500 Gems is exactly ten singles. Ten-pulls only save time. Single pulls let you stop the moment you hit the unit you wanted.

How many Gems does a 4-star unit cost on average?

The four 4-star units add up to 0.5%, so one 4-star every 200 pulls on average, or about 10,000 Gems. A specific one is much more: Spartan at 0.19% averages about 526 pulls, Samurai at 0.06% about 1,667, which is why pity matters.

What is a featured banner?

The banner rotates a featured 4-star unit (creators mention a Samurai banner and waiting for Spartan to be featured). Check which unit is featured before spending a big Gem stack.
