Can 3s Beat The FINAL CC | CC#12 3 + Dobermann Risk 18

#Arknights Back in the CN run of this event, Dobermann Squad got close to risk 18 but in the end CN only got up to Risk 17. For EN It was up to me to bring it up to 18, and I'm happy to say I succeeded for them. Compared to Risk 17 I added HP 1 ( 40% Enemy HP). This was also with EN having a disadvantage due to there being no U-Official in this server. She gives a 7 second stun to all enemies in range, and Red Blade is not stun immune, so you can imagine how much she helps. For the last tag I had a choice between taking HP Up 1 or Red Blade 2 for 18. Red Blade 2 is an effective 30% hp increade for Red Blade, but that's not the hard part. The hard part was his 5 seconds of invincibility. That's 5 seconds of Melantha and Doberman's skill time that he waste, but also he spends 5 seconds for phase transition as well, so effectively half of Melantha and Dobermann's skill wen to waste. I could not figure out a way to fight Avenger like this so I bit the bullet and took 40% hp instead
