Is it worth getting upgraded Iban staff for early rex grind? Or just use air blast?

[rain hornet]

just seems like i may as well get upgraded staff since diary right

like i don't really get this description, aren't they the same thing?

either way need to spend 200k

If you upgraded the staff before the diary came out, you just have to equip it (first option)

If you don't have the attack level to equip the upgraded staff, just upgrading the staff counts (second option)
