@Ckwng: Neither can we discount the fact that ASW formula is unknown for combined fleet. As for your experience, boss has 130HP, a scratch would deal 7-9 damage regardless of armor.

Here's the other source provided by Progeusz for the record https://youtu.be/kccUkptcU5w?t=283

As of Reikyu's latest test run, seems like there's something wrong with anti-sub damage formula in combined fleet instead of hidden armor reduction.

The latest Kuma's miracle with 10 armor roll on Hard boss (Head-on) can only be summed up in two words..."black magic"
