DrkDragonz66's video: Arknights - Annihilation 3 Fast Clear with 9 Operators 28:38

Silverash too OP Notes: just kill things as fast as possible. Using Silverash S3 at 1s after killing the dog for 19/400, it kills the first big rush fast and comes back in time for the second big rush. Retreat Texas as soon as you kill the jetpackers in the back, to redeploy her in the frontlines. You can survive the invisible mages until the 5-wave at 161/400, need Silverash S3 for that. The way the bombtails hit Silverash allow him to survive the 5-wave at 264/400, since the first 3 hits do like ~30% dmg, not enough to kill him but enough to trigger Saria heals to survive the next 2 bombs. Silverash S3 CAN NOT be activated during this, because they fire instantly and will kill him with the -70% DEF from S3. Pre-activate Silverash S3 right before the 350/400 Crasher/Mage/Drones rush to kill them ASAP, then retreat ASAP to redeploy Silverash behind Saria for the Red Crasher. This is because the Red Crasher will one-shot Silverash with S3 activated, so this allows him to survive. Activate SIlverash S3 right as the 1st regular Crasher shows up at 380/400, and use S3 to kill the regular Crasher and weaken the Red Crasher. Retreat once S3 runs out to redeploy in front of Saria again. Then redeploy Silverash and use S3 to kill the final drone ASAP, S3 will not recharge in time without retreating/redeploying. Blaze is for ranged damage + tankiness. Specter is for damage + passive healing the crossbow shots. Platinum is behind Silence, so Silence can heal Saria as well. Might be able to switch them. Silence has her drone to heal the bottom half, which has no healer. Possible improvements(?): Maybe try switching Blaze/Lappland positions, to kill the crusher faster and kill the last drone faster. Platinum/Silence switch, since Saria doesn't really need healing.
