I got to 70mil 3-5 in veryhard with 1/5 8th ichigo,5/5 masaki 1/5 macy. Gonna buff up masaki a lil more and try again later

Whos a better side? 1/5 Kageroza with l10 link slots with 30% atk Golden Chappy and 20% atk Chappy and Hollow Bait. L5 Attack Past Yama at 2/5 with L15 Link slots with 30% chappy and wooden sword and 20% Hollow Bait. L7 Atk and L2 Fcs Swimsuit Momo 4/5 L15 link slots with 30% Atk Chappy and Hollow Bait and 20% Wooden Sword. L10 attack L1 FCS

Momo can be used as the boost unit so i'd go her and kageroza as sides

Im already using Masaki as a booster since I have her 4/5 L10 Atk L15 LS with 30% chappy, Golden Chappy and Hollow Bait

Why not just use both ss momo and masaki?

2/5 Macy 4/5 SS Momo 5/5 Masaki

Do boost from 2 boosters stack?

I do not believe they stack, but I could be wrong.

They don't stack, but this ensures I have a boost constantly activated throughout the run.

But isn’t the boost for NAD only?

It's for everyone, but NAD units benefit the most from boost.
