Persona 5 tips for the cutest bartender in the world

Charm bath on Mondays and Thursdays, may be better to do this just once a night. Study at the diner when it's raining for 3 points in knowledge and 1 point for another stat depending on what you eat.

Buy the SP recovery waters from the vending machines at: School Courtyard, Outside the bathhouse near where you live, arcade. Can be done once per week at each vending machine.

Raise Death (Goth Doctor) to 5 for SP recovery accessories, 7 for half price. Very important for going into dungeons as little as possible.

Fortune (Fortune Teller) Rank 7 gives you the ability to gain points with an Slink of your choice once a day, at the cost of 5k yen. Raise that SLink to that level and spam the EVER LIVING FUCK out of that ability. 100k investment is well worth it (you get it back anyway).

Temperance (Teacher) is a useful social link. Rank 10 lets you go out at night after entering a dungeon. Temperance will also do your laundry, make infilitration tools, make coffee, or make curry for 5k without spending any time (becomes free when maxed).

Heirophant (Sojiro) has a FUCK ton of points to go from 3-4, but don't sweat it too much because you can't progress past 4 of his Slink until after you beat the Desert/Pyramid dungeon. Abuse Fortune's Rank 7 ability to raise the points instead of wasting time getting them.

Flower shop job is a decent activity if you find yourself with nothing to do as it's day or night, 3k pay and gives kindness, which is a hard-ish stat to get.

Grind as absolutely hard as you can when you enter dungeons. But outside of the first dungeon, which is actually pretty hard, I went as far as I could in every dungeon the first day it let me into it. And tried to get to the end before I left. It gets easier if you raise Death. Because you get SP recovery accessories. Guns don't do damage until later in the game, so conserve ammo and just use them to knock people down.

Do Empress (Haru) as soon as it appears late in the game. The carrots you grow give huge amounts of SP, which will carry you through the relatively difficult final dungeons.

Save up Mementos quests and do them a lot in one go. Make sure you travel as far as you can in Mementos each time you go. Many social links will require you to go into Mementos to max them.
