Grade damage thresholds for the Alliance Boss rise steadily through the first eight tiers, then lock onto the same number all the way to grade 20.

Seven Jumps, Then Nothing 📈

Pushing an Alliance Boss from grade 1 up to grade 8 takes progressively more cumulative alliance damage at each step. Once grade 8 is reached, that climb simply stops. Every grade from 8 through 20, thirteen grades in a row, asks for the exact same 77,000,000 damage total. No extra scaling waits past that point.

Rally Attempts Stay Untouched

R4 members and above can manually summon the Alliance Boss near your base once your alliance's challenge progress qualifies. From there, a single Lord can fight it alone, or the whole alliance can Rally against it together. Choosing to Rally doesn't burn any of your daily Rally attempts, which are normally a limited resource you'd rather save.

One Reward, Once Only 🎁

Every Lord who takes part gets a random reward the moment an Alliance Boss falls, but that particular reward can only be claimed once per Alliance Boss. Grades from 9 onward are also tied to specific alliance seasons, so what your alliance can actually fight next depends partly on where it currently sits in its season progress.

Now that you know the grade 8 wall doesn't get any taller past that point, is your alliance still holding troops back just in case, or pushing every Alliance Boss fight at full strength?
