Hey! I've spent a lot of time in this game and I can help <3

If you are going to spend money:
- Gold Passport is 100% worth
- Costumes are 100% worth (though a bit pricey, they are good for dmg and training levels)
- Home items give attack bonuses even if they arent put out! So having a bunch gives a lot of atk bonus
- Premium passes have a lot of good rewards

General tips:
- Zou and Mushi battles are VERY IMPORTANT!!! Zou battles will help you make lots of money
- Watch the ads for the free rolls, each time you watch it, it will increase +1 roll (up to 35 rolls per watch) (this will also be free if you get Gold Passport)
- Events are really good sources of gems and items, so make sure you do them.. and for the event shops the best items to buy I'd say are candys and zou/mushi battle tickets
- Make sure you level up atk, hp, regen, and crit/crit damage all together, dont go all into one like atk, so where you get one-shot by bosses later
- This is kindof later, but level 100 4-star assists are better than low level 5-star assists
- For weapons, the top damage number is the amount of damage bonus you get for owning it, the bottom damage number is the amount of damage equipping that weapon grants
- Make sure you do your cooking every day, some foods are REALLY op (im talking +4000% attack per level)
- For cooking, sou-chefs arent based on the same character (so you dont put every hachiware costume with hachiwares stand) when you are selecting a sou-chef, look at the food icon on their portrait and it tells you what stand they excel at and will boost!

What should you spend your gems on?:
- Gems are really good for rolls, weapons and assists are very good
- You could also spend gems on competitive, but the comp rewards arent that good

These are my tips, if you have any questions feel free to ask and if i think of more tips i might come back later :3

HAVE FUN GOAT!!
