vitrusa can be replace with goldenglow s2m3

[@abdullahabad4325]

in the last day, we can replace typhon with wis'adel

[@Doppelshifter]

Finally managed to clear it, but I had to make a quite a few substitutions and adjustments 'cause I don't have the same ops (or them in the same levels): - I brought Ines as my third Vanguard, so I could use her to reveal assassins in the corridor approaching Saria (and also so I could use her to help left side in the last stretch) - I used Penance instead of Mudrock 'cause she's what I have, but instead of Croissant, I brought Jessica Alter S2 (because of her ranged burst, her ability to deploy a shield as an emergency measure in case Penance died, and because she reveals assassins for the left-side lane with her module) - Instead of a caster, I brought S1M3 Rosmontis (cause of continuous AoE arts damage and wide range) - Maxed-out Perfumer instead of the Berries, so her passive could help left side (Typhon + Virtuosa are enough to deal with the bards) - And here comes the biggest change: I brought Texas Alter *and April* as my fast-redeploys, so I could quickly deploy April on a distant ranged tile, followed by Texas, killing any distant towers that would otherwise keep dealing constant damage to Penance or Virtuosa. It also gave me a ranged fast-redeploy to help in any potential leaks in the last stretch (instead of having to redeploy Rosmontis early). With this, I was able to hold up almost until the end. After the center of the map was empty and all that was left was the left side, I could start re-aiming operators to the left side (including Horn and Rosmontis for extra bombardment, Ines behind Jessica for an extra safety net, and Texas Alter + April for extra burst. This strat allowed me to *finally* clear it, after a lot of failed attempts with other team comps (some closer to the one you showed, but that didn't really work for me).

[@ElsyeaR]

Thank you, you are extremely helpful as usual !

[@PajamasA]

Thanks for the guide!

[@shaynewalker1205]

Epic use of Horn! Her Skill 1 is so under used.

[@PajamasA]

Totally agree!

[@xgamermarco]

I starting to using her S1 skill for afk runs, been enjoying myself with it

[@evawally12]

S1M3 is sooo worth it

[@yvesp3070]

Thanks for guide, was painful, had to use some subs but made it.

[@sirukodr2502]

The most bastard cards and the most bastard enemies in the game. I'm sorry, but when an assassin blows off the floor of your best tank in the form of hoshi or nian, then this is already an imbalance. Or a spearman who has accelerated a little and is already almost hitting you. But these giants are especially fucked up, which cannot be blocked - this is probably the most disgusting enemy in the game.

[@GerardoOlimpia]

More disgusting are Weavers "Scissors men". They ruin much strategies.

[@GerardoOlimpia]

You can kill giants with chains. You don't need kill them with DPS.

[@yvesp3070]

Yeah i did have to reset 5 to 10 times tinkering with ecko afk blueprint but actively playing and trying to adapt. I generally do not have all of the operators that were used. I am lucky i was able to pass it. Otherwise i would wait for a low end guide to adapt. Mvp was Ela mines and Ascalon to slow down left lane. Shu sowing with mulberry skill to outheal the burners. Also Reed alter was subbed in for virtuosa (since i do not have her). Plus Surtr helidrop to clear up left lane assassin cluster at end. But yeah it was bloody hard.

[@sirukodr2502]

@@yvesp3070 If it weren't for these fucking spearmen at the beginning, then the level would be a little easier, but no, let's put the spearmen at the beginning so that they just take out everything from 1 point, even strong tanks like Shu, Nian or Hoshi.

[@SoilworkWT]

Thank you, did small adjustments only. Replaced mudrock with zue le (s2m3) Virtuosa facing right, because in moment they got stuck on saria they were refusing to die, virtuosa took care of it without really changing outcome from not facing up.

[@dixaba]

Normal clear was relatively easy for my underleveled ops (SL7 no mod Horn, E2 lvl1 Mudrock, E1 max Typhon (had to borrow her)) but CM made me think it's impossible without either panic investments or until rerun. Fortunately, replacing Saria with SilverAsh (thanks, comments!) and replacing Virtuosa with Pramanix S2M3 mod3 solved the issue: enfeeble from mod made it easier for replacements to survive, and reduced DEF from S2 + Fragile helped DPSers. Hail the Saintess and Eckogen!

[@angoankhachai9333]

For those who don't have chain casters built (or even for those who have, since my e2lvl50 Astgenne had trouble killing the assasins): Meteorite s1 is a good option, especially if you have her module

[@v4mp250]

Thanks again Eckogen

[@TBFM3]

After 15 tries with borrowed Horn(all my thanks to you), I finally beat this cursed of a map with my team missing a lot of tanks, good healers, or capable of blocking the assassin's first hit. So this is what I did: - I put my big boi Zou Le in the left lane to weaken the incoming assassin with Penance S1 standing right behind ready to finish them off. (Zou Le was facing right so his S3 could hit both lanes if needed) - The only AOE I owned was Fiammetta, so I placed Shining S2 to heal her constantly. - I have to put my faith in Warfarin and bait out the first attack of the Guitar guy by sacrificing Eyjafjalla and Pozëmka(at least they destroy the crossbow) - Put my Degenbrecher in the box so her S3 can hit both lanes. - Got Jess Alter S3 with shield ready to lob the big grenade across Degenbrecher, successfully stun the left lane, and cover Zou Le(She stood in Shining zone, so Shining could heal her and buff the DEF). - Siege S2 was ready to fill in whenever Penance was down. I can't deny that Zou Le was a big part of my success. His S3 can stun the assassin at the right moment so they just skipped the first hit. The cross-lane tactic with the help of Horn - Fiammetta helped me so much. After everything I tried (About 15 times) and many failed attempts with the same strat, this was what helped me beat the stage. My god that was painful to complete, but so satisfying when I did it. Thank you for the god-tier tip, man.

[@evawally12]

I love how flexible your strats are! I don't have Typhon, Virtuosa, nor Astgenne but I managed by bringing Suzuran S2 (no Mastery) and Passenger then borrowed Typhon ^_^

[@diamondrhino64]

Yeah eckogen you're my goat

[@shufleur284]

I was stuck for a while on this stage and when I used horn I one try it thanks for the video

[@douglashiggins9548]

Thanks worked great I used Thorny for Saria then dble down Saria in front after caster

[@alexandergonchar4453]

My Horn is E1L80 and S1L7 and she cannot support flares as yours in video. I suppose I should use a support unit as I lack masteries. I tried extra defender in front of Saria and below Saria, to no avail, those assassins leak en masse UPD: removed Saria at all, on her place I put SilverAsh and behind him - my E1 Horn. And it worked!!! It took my sanity reserves so, as I tried various positions for Horn

[@seraph_dalgon_9216]

Ya think a Mylnir could work instead of SA?

[@alexandergonchar4453]

@@seraph_dalgon_9216 If Horn uses flares as intended - yes

[@DarkHopeAssassin]

On my husband's account, we have neither Typhon nor Virtuosa. Let me tell you, getting everything right to go through was a HUGE challenge xDDD You make it look so simple here and everything works so perfectly but without these two, it becomes a HUGE pain xD At least we were successful in the end but all is well when it ends well. Of course, on my own account where I have all these folks, it went smoothly just like in your vid xD

[@JUN-hx4yd]

After using Horn in my main squad for over a year this is my first time using her S1 let’s go

[@LorDTestMe]

switched up some Operators, all I can say is that Ines and Silver Ash are the MVPs

[@zel6010]

If you don't have Horn like me, bring Blemishine S3. Place her where you would place Saria in this video. She can tank the assassins that come down and put Shu or Saria to heal her on the bottom right, diagonal from Blemishine to catch the assassins that teleport. Make sure Blemishine faces down and use S3 whenever possible against the assassins that come down. If you don't have Typhon, Fiammetta S3M3 can replace her, but you'll need meteorite or another similar aoe sniper that is strong behind her facing left to help Blemishine and Shu/Saria. NTR knight can be nice to bring in case Shu/Saria has some trouble with the assassins. I brought texas alter as well just in case for the beginning and near the end.

[@voltorian-games]

didn't have the war criminal Or horn OR mudrock and took typhon as support so uh replaced: mudrock with swole le (e2 lvl 60 s2 m3 module lvl 1) sankta psychopath with goldenglow (e2 lvl 90 s2 m3 module lvl 2) saria with shu (e2 lvl 90 s3 m3 module lvl 1) honeyberry (e2 lvl 80 s1 m1) texas/zima with courier/scavenger (both e1 s2, otherwise doesn't get dp fast enough to drop shu before the lancer guy bum rushes past) croissant with gummy (e1 lvl 60 s2 for the defense) astgenne with mostima (e2 lvl60 s3 m3 module lvl2) horn with cuora (e2 lvl 70 s2 lvl7 module lvl 3) also took another e1 defender and mlynar (and as mentioned before, typhon support for a full squad of 13) process: after dropping myrtle, drop scavenger where zima is, then courier where texas is (important, because courier has like 100 more defense than scavenger, he doesn't die to the starting trash mobs with myrtle's regen talent. scavenger with her higher atk will kill the ones that leak past courier) honeyberry placement is the same drop goldenglow where virtuosa goes after using scavenger s2 and killing the mobs that leaked past courier, recall her to get some dp back so you can drop shu to intercept the first lancer before he runs past typhon placement is the same drop in swole le where mudrock went recall courier after he kills the last trash mob from the beginning drop gummy behind swole le (where croissant went. seems inconsistent when the assassins do or don't one shot her though. are they regaining invis for some reason after blinking past swole le? if she does die then replace her with the spare defender, i used bubble e1 s2) drop cuora in front of saria/shu recall myrtle and replace with mlynar facing up at this point i tried alternating between mlynar and shu skill. if mlynar skill is active, he just kills everyone and shu's skill covers the downtime (you want to make sure shu healed goldenglow so the sowed tile covers the left lane and helps with leaks, not to mention the sowed tiles also increase the atk speed of the other units) after the last assassins from the middle are gone (only ones remaining take a tunnel to the left lane), remove cuora and drop mostima two tiles above goldenglow facing down swole le will probably die when all the assassins reach him. stall for mlynar's skill with shu's skill and mostima's skill, and use your remaining melee units to block the assassins to cancel their invis so mlynar can kill them yeah not having horn reveal the assassins in the middle to soften them up really made things super scuffed at the end. mlynar skill timing is also probably important so you can have it up in the end when the rest of the assassins bum rush swole le, but unfortunately i didn't actually keep track of when i was using his skill my brain is too smooth for that holy frick this stage was turbo cringe🥴

[@abdullahabad4325]

I don't have typhon, horn, and ray... well, time to force it with brute force

[@soulkibaart]

Actually managed to clear it first try after being terrified of this Stage with my Squad being: Horn S1 without Module from Friend Support Shu S3 to hold down the Middle (The Teleport helps a lot with keeping the Assassins in check too) Ines under Shu for Invis Reveal and Binds Eyjaberry S3 Hoederer S3 M3 and Degen S3 M3 to hold down the left Side Virtuosa S3 and Suzuran S3 to Support Left Side Suzuran and Shu were key for slowing down the Big Guys and the Assassins so Degen and Virtuosa had enough time to kill them. And Hoederer's Bulk and Stun helped a ton too.

[@R3Lynx]

I see Horn, I approve Horn

[@InvincibleKonchu]

I wonder if you do an extra tank infront of Saria if you can shove a Lord behind the tank tp help kill??

[@neovagras980]

I don’t have Horn or Mudrock. ._.

[@Eckogen]

Borrow Horn. You can double up on regular Defenders in place of Mudrock. Just make sure you kill the Assassins.

[@SimbahPardimin]

Can i use Eyja or Exu facing up instead Typhon?

[@Eckogen]

You could, but do you have really good DPS on the left side to deal with the Assassins and Spatulas?

[@justinelisayana7156]

You know it's hard if it's brain dead

[@YouuuMeeee]

Can i use rosa s2 instead typhon?

[@Eckogen]

Probably. Gotta watch for the Guitar guys. Interrupt them.

[@Rai98Chu]

Typhon can also be replaced with Rosmontis S2M3. She consistently stuns the guitar guys, and reaches far enough to also stun the big guys coming into the leftmost lane

[@almondbread8255]

I'm getting increasingly more frustrated with 3 spooks on typhoon banner

[@Sixon6845]

I knew this event is BS when u choose not to make a low rarity guide

[@elliotmay7571]

I have no Horn and I tried to substitute with Firewhistle... believe me when I say I almost went bald, and that's on normal mode

[@Eckogen]

Unfortunately, she won't do much as Horn will stealth reveal the enemies.
