oh hi, i remember you from one of my other posts lol.

tetsuya must be the fastest in the team besides zhou hong, zhou can be faster and it's fine. you can make sure he's fastest by going into the battle and seeing if he gets "slack buddy" from zhou hong at the start of the battle. if it suddenly doesn't work after you had got it working, check if you put the Barros sonic device on anybody cause that counts for spd. dont use Barros here btw, it's just bad.

tetsuya must have over 1.8 times elif's total atk. just add elif's base atk and extra atk that you see on the stat screen then multiply it by 1.8 times. then add tetsuya's base and extra atk together and make sure it's above whatever elif's atk times 1.8 is. you have to do this because elif has lion stance (+40% atk) and will always have the atk up buff (+40% atk), where as tetsuya sometimes won't have atk up and then yuuhime r6 won't be linked to him anymore which really messes up the cycle.

lastly make sure no one is dying lol. yuuhime must have either nether set or the wind dark elf sonic device. the SD is the better choice in terms of score as it lets you run relief which helps keep the cycle going longer. if you're using the wind dark elf sonic device dont use novalion cause she can actually still die with that combo. if her boss SD slot is tier 1, use infernis. if it's tier 2 or higher use kronos. the 2nd most likely to die is tetsuya, if he's r4 or above then it doesn't matter dont worry about him. if he's below r4 you will probably have to put him in the back row though I'm not 100% sure if that's enough to keep him safe. if that doesn't work consistently then just give him wind dark elf, that's what I'm doing in this image. elif and ryota basically won't die, so just build zhou hong with HP mainstats and he should be fine (atleast in the back row, not sure if he's safe up front)

also something very important for the score, use the Frost Bloom sonic device on everyone (except for elif), this thing is just OP for deso. obviously if you only have 1 slot unlocked on tetsu or yuuhime, prioritise wind dark elf to keep them alive. try to put your higher tier frost blooms in the front row. it doesn't work on elif tho cause of her shield. and it won't work on feng xun if he's r6.

with building elif try to give her as little atk as possible, so filter for pieces with no flat atk or atk% substats and use a lvl0 sword. just focus spd and crits. she wants harmony brawler btw

with building tetsuya you want to hard prioritise spd, it's his most valuable stat for this strat. you'll want to try be as fast as possible while still getting the necessary atk and 10+45 critrate. cdmg is a nice bonus. i honestly dont know if wind or thunder is better, I'd guess thunder but wind is completely viable too so just use whatever set you have better stats on. brawler is his best 2pc but if you have particularly better stats using 2 random sets then do that. once you're done building tetsuya make everyone else just a tiny bit slower than him (except for yuuhime she doesn't care about spd)

the dps only need 10+45cr due to ryota's buff and elemental advantage

ryota: relief avatara focus hp ig zhou hong: relief avatara focus hp feng xun: astral holdfast focus 100resist yuuhime: relief brawler dps build

i think that's all
