basically 2nd team will survive long enough to fire off a ~95% solar blast (20k damage), then 3rd team will stall enough to fill up a second gauge for the 4th team (42k damage), then you'll need to pick a solar blast team ally (weird, I know) to further optimize damage.

Start with #% light gauge only works on 1st team if anyone is wondering. Putting in Peach, Strawberry Candle and Bipinna Cosmos guarantees at least 2 solar blasts per battle, 3 or even 4 if you have Cattleya and Mei Plumblossom.

When the second phase comes in and we get the 10x solar blast option for 150 chocolate, it will actually be better to use that option over 20 chocolates for the higher level raid boss, since the cost performance of 10x will be better than 1x solar blast.

1x damage for 20 chocolates: 20k + 42k from team 2 and 4
10x damage for 150 chocolates: 200k + 420k from team 2 and 4

Number of battles required to match 620k damage from 10x by only using 1x is 10, so 200 chocolates.

3x damage three times is effectively 9x damage, which is lower than 10x at 150 chocolates

5x damage twice is 160 chocolates, which is the second best option right now until second phase.

the only way to further optimize this squad is by adding Rose on the first team for an additional +20% light gauge & counterattack but



o-oh...
