Treasury

The treasury is a building that will help with your gold needs. It doesn't actually produce gold; rather, it recovers a certain percentage of gold that you spend. This gold can then be withdrawn later.

The percentage of gold retained increases with the treasury level, up to 25%. Every level requires a higher player level to retreive the gold, up to lvl 35 which is the highest player level currently attainable.

The gallery below shows the treasury at all different levels.

The treasury does not level on its own, meaning you can save as many treasury pulls as you want for later instances. You shouldn't let it amass huge quantities of gold before the treasury reaches the 25% refund, as you'll effectively be losing 5 to 10% of the gold you're spending in that time.

The table below summarizes the current best knowledge of the treasury details. The building is level 1 when you start the game, and the tutorial makes you repair it, which puts it at level 2.
