So i took time with my fav Descendant before this and with the strategies learned i thought how i can beat some bosses as fast as possible with Viessa. For my surprise, i finished Dead Bride in 46 seconds. However, my build was messed because i was using... Focus on Singular (facepalm). This happened because i was finding builds to kill Dead Bride without Cold Bloodedness, since her and other chill colossi has immunity to chill debuffs, making the full polar night components useless*. Even trying with Absolute 0 or Hypothermia, Cold Bloodedness combined with Secret Garden still deals way more damage. For now i killed Dead Bride in 30 seconds. Could be better? Maybe.
For those who are concerned about my character build, keep in mind that i had done this to beat as fast as possible. Even though Dead Bride's attacks are easier to dodge, i used 2 mods for survivability and extra damage. Still, You can use better survivability modules and finish void intercept battles in a short time.
* You can stack the set 4 of Polar Night components not only with chill ATK mods or Viessa's frostbite with Absolute 0 mod, but also ice shackles, to deal more skill and firearm critical hit damage. All of the colossi have immunity to frostbite, so you should not use polar night with Absolute 0. Only chill ones are immune to ice shackles (sad). Against chill bosses, Slayer components are the better way.
Enjoy! Have a great day!
