Matchmaking in Gem bay

Gem Bay matchmaking is calculated based on your Max Historical Power (HP).

How to know the Max Historical Power?

You have to go to another player’s profile. The Max Historical Power is shown in the red box. You can see it from your profile but if you make a change that increases your power and you don’t perform any battles, it will not give you the right value.

Max Historical Power cannot be lowered so be careful what you improve on your team.

Each spot you face has a certain power.
The calculation is done by the sum of the best fighters in your castle in your barracks, similar to the bracket system in arena.
If you put additional fighters in your Gem Bay expedition, try to get their power as close to your weakest fighter from your main group in your barracks.

Just put your Max Historical Power in box A1:
