Jujutsu Kaisen Cursed Clash

get ready for a +100 hour grind!
You need more than 1,450,000 exp points to level up all 16 characters to level 25 so you can obtain this achievement.
I have found the best exp farming method

Best part is that is actually in Solo mode. And it takes about 10 minutes average to get from 4,000 up to +5,500 exp.

SIMPLY SAVE AS MANY RECOVERY POINTS AS YOU CAN, Your recovery points are the ones you get at the end of every round so you recover health and/or lives.

Using BINDING VOWS and COMPLETING CHALLENGES during fights give you more Recovery points

Select rush battle, play alone with cpu and then set the skill level between 15,001 and 16,000 So that you fight Grade 1 curses. If you haven't got enough skill just play until you reach more than 15,000 skill. I advice not to increase the difficulty above 16,000 skill

Your partner is picked randomly so I advice you go back and select the game mode again if you don't get a "good" partner.

Best Partners in my opinion
1. Sukuna
2. Gojo
3. Megumi Fushiguro
4. Novara Kugisaki
5. Suguru Getô
6. Aoi Todo
7. Maki
8. Panda

Worst possible partners you could get are the others, specially Okkotsu who gets owned first round.

Just complete as many challenges as possible and always pick 3 Binding Vows.

Don't use recovery points unless it's very necessary.

In case you are having trouble I recommend you Use these 2 key items that make this very easy.

1. Talisman of Leeching +2
This Talisman lets you RECOVER HEALTH as you damage enemies. Basically reducing your chances of dying and having to spend 3 recovery points to get a stock back.

2. Giant's Pendant +2
Increases health by XL (Alot)
And increases damage by L (Decent)

If you finish the 3 rounds with just 1 life left, don't worry, it doesn't affect the exp score. Just the recovery points matter.

If your character is at level 30 you get the most recovery points possible. I had games with +6,000 exp rewards when completing all challenges and keeping all recovery points (27 recovery points)
