This doesn't merit a full blog post as it is a single quest, so a wall post will do. This is on Quest B44. This merits a calculation only because this is the hardest quest in the entire game.
Assuming the ASW multiplier for ASW gear is 1 (not proven), A lvl 63 Inazuma Kai with 2x Type 4 Passive Sonar 4★ + Type 3 Depth Charge Projector ★ (What I'm using at the moment) will deal:
94.3 raw ASW damage
56 damage Parallel
45 damage Head-on
Chuuha numbers are too low to be viable, Taiha and Red T numbers are too low to be viable. In those cases, the quest is lost unless critical hit occurs, repeat.
75 damage Parallel, good health
60 damage Head-on, good health
52 damage Parallel, chuuha
42 damage Head-on, chuuha
Taiha and Red T numbers are too low to be viable. In those cases, the quest is lost unless critical hits occurs, repeat.
The submarine faced has 30 Armor 37 HP
Minimum damage required to sink: 40. (Hits 19 + 19 damage with two subsequent activations of 21 Armor). This is 45 if 3 battle nodes are fought.
Maximum damage required to sink: 58. (Hits 19 + 19 damage with two subsequent activations of 39 Armor). This is 63 if 3 battle nodes are fought.
Average recommended damage required: 49. This is 54 if 3 battle nodes are fought. These values are close to both healthy Line Ahead Parallel and chuuha Double Line Parallel, while the minimum values are also exceeded in both cases with Head-on.
Under these circumstances, an Admiral should choose Line Ahead if Inazuma is NOT chuuha, Double Line if Inazuma is chuuha, and abandon sortie if Inazuma is taiha (kuso risk). Since there's only a 1/3 chance of the submarine even appearing to begin with, the power of the surface fleet should not be compromised any further than these values. It is possible to use Double Line if healthy and Diamond if chuuha for a significantly greater chance of killing the submarine, but in exchange this sacrifices surface fleet firepower, making it less likely to S-rank the node.
Node Support shelling of the usual builds is used, and pretty much compulsory - especially for surviving the 2 Ru-Flag 1 Nu-Elite formation in node F. Since at maximum only 20% of attempts will make it to the boss, boss support is a Very Bad Idea.
I just put a post on the quests page asking for advice about this lol ^^ I ran it a few times already before I remembered the routing requirements. Unfortunately I have a lvl 15 nagara and barely kaied DDs, I feel like giving up, ugu.
Yeah I've completed similar quests with lower level ships and at least a few key ships to secure that S rank, but that routing is horrendous for this locked ship requirement. Actually I was barely getting through the few nodes past the sub node, and started using node support. That's when i remembered the routing, which would make this a bit too expensive for my tastes.
Anyway thanks for the short tips guide! I might change some equipment based off your advice, I was using 1 depth charge per DD and a full ASW DD so I didn't die so much.
A 200-sample lv.99 normal-morale test reposted at http://bbs.ngacn.cc/read.php?tid=9071590 show that Mikuma Kai with 2* no.3 gun have 91.2% accuracy and Mogami Kai with 2* no.2 gun have 69.7%. p-vallue for the difference is 1.071*10^(-7) and is significant.
Note that it didn't suggest if no.2 gun have yasen acc bonus or not.
Thanks for taking the time to answer my questions regarding the use of (F)BBs vs CAs in Winter 2016 E3. Just thought I would thank you here instead since you last updated that Winter 2016 blog post pretty long ago.
Thanks for your contributions to the Winter 2016 Event, without your assistance the implementation as well as the updates of new information cannot be effectively done let alone without the necessary manpower.
Will be counting on you in the future for your helpful contributions!
