Guide for beginners:-

Sea 1 is the area that most people quit because they don't understand the main mechanics,they feel the game is way too repetitive.

Well the reason you should still keep playing is:-

Sea 2 has way more interesting stuff other than grinding such as trading your fruits with others,raids,race v2 etc.but you are not supposed to understand it now.

Sea 3 has even more stuff.

Fruit:-

So There are mainly 2 types of fruits-With and Without an M1.

So which should you choose?

Ans-If u prefer a easy and fast grinding pace then choose fruits that have M1(Eg-Chop,Ice,Light are the ones which you should choose for first sea)

If u prefer a challenging,fun and fast grinding pace then choose fruits without an m1(u can group up npcs and constantly use your moves which are much less boring imo).

Some M1-less fruits that are recommended are as follows

Magma-Magma deals massive dmg and if u awaken it in second sea(you won't understand it now),it becomes the highest dmg dealing fruit in the entire game and the second best fruit for sb hunting(which is also smth u will understand later)

Ghost-Ghost is better than Magma for first sea as the ghost busters which double your dmg output allows you to deal a lot of dmg.

Smoke-It is also an excellent choice for Sea 1.With its F move

U cab drop bombs on npcs

I will cover other parts in other posts.
