Squad 1: Activation rate, with Fritillaria to leech from it. On the first round she generally gets 8%, on the second round another 2-4%, on the third round 8-10% more.
I might replace Tachibana or Moonvine with Cyrtanthus sometime, not decided yet.

Squad 2: 50% Sun Gem increase, with Leucocoryne to benefit from the increased amount of sunblasts. Black Baccara is going to get replaced with Alpinia sometime soon

Squad 3: No idea for any tactic yet. I'll probably just stick with "lots of AOE and just above avarage speed".

Squad 4: Also no tactic yet, but Hypericum is the next slash girl in line for leveling, and she could turn this squad into a counter attack squad.
