Bear battles work very differently when you’re joining someone else’s rally.
When you join a Bear rally, you use the rally leader’s stats and heroes. The first 4 joiner heroes that get locked into the rally are also used for every joiner’s individual battle.
The only thing you contribute to your own Bear score is your troops.
For example, let’s say you join a rally where the leader has all stats at +1000%, and the first 4 joiner heroes are all Chenko.
First, the battle is simulated for the rally leader using their stats, troops, heroes, and the 4 locked joiner heroes.
Then, the same rally leader’s stats, heroes, and joiner heroes are used to simulate the battle for every individual joiner. The only thing that changes is the troops, which come from each joiner.
So, if you send 100k troops with 80,000 Archers, 10,000 Cavalry, and 10,000 Infantry, your battle will use your troops but the rally leader’s stats, heroes, and joiner heroes.
This means that as a joiner, joining a stronger player’s rally can give you significantly more Bear damage points.
