Tricaru failing at DB12

[distant kelp]

I'm confused what should i farm for my tricaru team to make them more stronger. Currently i can do BJ5 almost 99% success rate. I currently want to make my tricaru team stable, my tricaru can do NB12 100%, PC10 95%, and sadly struggles on DB12 mid boss but somehow when i pass through it, i don't see any fail runs on the boss itself. Here is the video sample and their stat. My verde is on fatal/blade, and my tricaru is on 6x set deter and 3x guard. May i ask if my problem is my verde, icaru's, or both of them? and should i farm grind/gems or continue upgrading their runes since some of them are 5* only?

pretty sure you just need more speed on the icarus

max tower would also help a lot ofc

How to Tricaru

Monsters
3x Icaru(2a)
Verdehile

Team
Verdehile+Tricaru = DB/NB/PB

Which runes to use
Determination: These can be crafted with crafting materials found in Water/Light rift.
See chart below for a visual explanation.
For returning players, guard runes can be used if you already have grinded/gemmed guard runes.

Stats
Icaru
You want to reach 3301 combat defense in order to teamup with 3 monsters
~20%+ accuracy, to land your def break(more is better).
ATK/CR because while they need 3301 Defense, their damage comes from having ATK/CR
Verdehile
100% CR, speedtuned, 91k eHP nb12 (78k eHP db12), rest in ATK/CD ~about +1827 atk, 175cd / 3500 dmg s1 boss defbroken in swop.
The stronger your team, the squishier he can be.

Basically you want the ideal setup, this was if the first dog doesn't team up. Then the second dog will still outspeed the enemy and teams up

The reason why you're losing is because you end the wave with the first dog.

Verde moves every 4th turn.
The turn after Verde is the fastest icaru. If the wave ends on the turn of the fastest icaru, his #2 skill will be on cooldown in the next wave

ohhhhhhhh i see, i thought i already hit those ideal speed, im so dumb that my speed towers aren't max yet to use the ideal setup 😅

soooo if i understand correctly.... (correct me if im wrong), i should increase the speed of my 2nd dog only (the +14 one)?
