Ranking Up units

Outside of items and synergies, the other important way you will strengthen your team is by leveling up/ ranking up your units.

To do this, simply find three copies of a single unit. When you have these three copies, they will automatically combine into a two-star version that will enhance their battle potential.

In the image above, we already own two Fioras and have found the third one in the shop. It doesn't matter where they are standing, on the game board or the bench. After clicking on that Fiora on the shop, it combines all three into a two-star version. This can be identified by right-clicking the newly created unit; we can now see two stars instead of one. Furthermore, her stats and skills are on a whole new level.

Units from carousel and shop are always one star but are easily ranked up to two-star versions. These units can be ranked up again to become three-star units, but this can be a difficult and expensive process. Nine copies of a single one-star unit, or in other words three copies of a two-star unit, need to be found for a three-star unit to be created. Trust me, you're gonna be mind-blowing how powerful a three-start unit is, however, it still depends on the progress of the game.
