Here’s the remaining data on the 5* ninjas on defense.
The 572 MP for charge1 have been screenshot verified in my posts 75 (571 MP = not charged) and 82 (572 MP = charged) above, so I’ll only go for charge2 and charge3 now.
Test 1 with 5* Topaz 3-70 with 7% mana generation bonus from mana troops level 7 (+7%) getting 1143 MP from 10 regular turns and 1 turn with -34%:
1143 = 1000 x 1.07 + 100 x (1.07 - 0.34)
=> charge2 is not charged from 1143 MP, as expected
Test 2 with Topaz with 0% mana generation bonus getting 1144 MP from 10 regular turns and 4 turns with -64%:
1144 = 1000 x 1.0 + 400 x (1.0 - 0.64)
=> charge2 is charged from 1144 MP, as expected
Test 3 with Topaz with 5% mana generation bonus from mana troops level 2 (+5%) getting 1715 MP from 14 regular turns, 1 turn with -24% and 4 turns with -64%:
1715 = 1400 x 1.05 + 100 x (1.05 - 0.24) + 400 x (1.05 - 0.64)
=> charge3 is not charged with 1715 MP, as expected
Test 4 with Topaz with 5% mana generation bonus from mana troops level 2 (+5%) getting 1716 MP from 14 regular turns and 6 turns with -64%:
1716 = 1400 x 1.05 + 600 x (1.05 - 0.64)
=> charge3 is charged with 1716 MP, as expected
As a result, (5*) ninjas on defense are verified as well, so only the tide speed is left now.
