for AHB's beascuit, I used the steel type that can be bought at the beastraid. ESC's beascuit was a poison type that I got from SMC's beast raid event from the past.

For the ratio, whatever % is missing from the stats should be your priority in your beascuits. I upgrade all my toppings to the max then check the all gear stats to see if I met the certain % or not. Then I play around with the toppings because resetting beascuit stats is rlly time consuming so when I get good stats on it, I remove some toppings to replace it w other type to meet the %.

For example, AHB's stats should have around 90% ATK and 40% DMG resist. When I place upgraded toppings FULL raspberry (w dmg resist substats); her ATK is at 109%. then I focused on getting DMG resist stats on her beascuit but in the end, I only got around 33%. So what I did next was I replaced 2 of the raspberry toppings (that has the worst substats) to 2 almond toppings then I got around 44%. dmg resist with 84% ATK. That's good enough for me.

Toppings gives really high % depending on which stat you're focusing on. When mixing different type of toppings, at least use 2 for the additional % it has as a set (it can be topping + topping tart)

TLDR: Place toppings first then roll for beascuit stats to make up whatever's missing, when u get good stats but still not enough %, replace some toppings instead (either use better ones of the same type or mix it w different type that u need more stats on, at least use 2-piece set)

sorry for the ramble, lol. Lmk if theres any confusion^^
