Read the boss skills and stats on wiki Read the common introduction and disclaimers Timing precision Hard DPS check Medium Tank check Hard

This is a CM that can be very annoying due to various sources of lag and RNG However do not be scared by the double Hard If you time Unicorn precisely then the Tank check is naturally solved Or if you bring tanks and Perseus then Perseus trivializes the timing precision You must either bring a vanguard heal that activates every 20s or have carriers that reload slightly faster than 20s for a screen clear Toolkits alone will not do the job The best ways to get the heal are Primary Healers Recommended Unicorn who has the benefit of doing more damage and healing than Perseus Must be timed properly 19 92s 19 93s probably works for 5 7 minutes and 19 94s 19 96s probably works for 10 minutes For a level 125 Unicorn in love BF 109G and Ryuusei is 19 95s in game with 2 RLD tech also try 3 RLD if 2 doesn t work or use HVARcat and Ju 87d with 0 RLD tech Do not bring cats with CVL RLD Passing the first few stings relies on RNG because if your vanguard is too close to the boss then they ll get hit before Unicorn heals Perseus who suffers from low damage and lower healing She struggles to keep a sandwiched Aurora alive so Eldridge is needed A Plymouth Aurora Eldridge vanguard can survive for 7 minutes which may not be enough time if your main fleet is weak Furthermore if her heal lags less than Elbing s sting then Perseus can cleanse your vanguard of venom right before Scorpion s Mist which lasts for 2s expires If your ships are moving they regain the venom by touching Scorpion s Mist Minor Healers not recommended due to how much damage the boss does Little Formidable requires >90% HP so to avoid her being burnt bring at least one non concealed main fleet ship or pray with a full carrier fleet Marseillaise for a full French vanguard Boise with a level 8 healing skill Ognevoy has a 10s heal but she desyncs after like 5 minutes due to activating 4x as much as Elbing s skill Due to a possible bug most vanguard ships get the 60% damage buff permanently even if they get healed Ships who gain lose or refresh another source of damageRatioBullet like Bayard or Bremerton lose the free 60% damage until the next venom mist Also damage may be tight so GLHF if you don t have Aurora Time graph for skills

This section is for manual only and only months with a notable manual strategy may have a manual section If you have fast reflexes you can use a carrier s airstrike to clear the Fatal Sting barrage before it hits your vanguard Keep to the left edge of the screen so that you have more time to use the airstrike Manual should allow you to forgo a healer for more damage

This fleet and gear won in 7 25 using half tech a random gold purple submarine fleet with random torps and no synergy and the free cats level 30 Drake and level 25 Every Mid End BB example fleet

Any oaths or tech just keep the faster black white shell BB blocked behind the slower BB who is using AFCT HSFCR High End BB example fleet 1

Same explanation as High End BB 1 But with Ognevoy instead of Unicorn the fleet has to win faster due to Ognevoy s sync drift and the lack of healing High End BB example fleet 2

Again any oaths or tech just keep the faster black white shell BBs blocked behind the slower BB with AFCT HSFCR Removing Aurora and Plymouth is a big loss in DPS but the extra BB may recover some of it Marseillaise is required because she heals French ships every 20s Elbing does a lot of damage so Brest is required if your battle will go longer than 5 minutes The third ship can be Le Mars for fleet buff Mogador for damage or L Audacieux for worse Mogador French example fleet

For the super lazy people who don t want to time Unicorn you can use Unicorn and Perseus together This fleet won in 9 49 with no subs half tech a single cat without flame and no HVARcat or Skyraider Mid End CV example fleet

Forgo healing and use CV screenclear to wipe the sting barrage This requires carriers to be slightly faster than 20s which is a high bar for CVs but not CVLs like Unicorn Due to the 1 5s start of battle delay if your faster CV has exactly 20 0s reload the screen clear will happen 0 5s after the boss fires the true damage barrage If your vanguard is too close to the boss due to RNG then they ll die in that 0 5s So you want CVs to reload slightly faster than 20s but not so fast that the CVs strike before the barrage appears Or just be a normal person and use the other fleets
