Question about world bosses *Spoiler*

[Hanabi]

Hi! I´m just wondering at what point of the story (if possible don´t give me spoilers) I shouldn´t continue with the main story, if I want to kill all of the field bosses first.
I have been trying to do all the side quests possible for me at my current lvl and found some bosses like the dragon at the top of the tower or the thing that spams totem like monsters which are around lv 65-75, so in the main story I´m at the point where we land on Rena and i´m allowed to go back to other zones, everything is pointing that I´m heading to the final fight and my party is at lv 45.
I would like to know if I can continue with the main quest without being locked out from going back to other zones or if once I go to explore Rena there is no way back.
Thanks!

The level 60+ monsters like the ones you're talking about are actually postgame enemies that you can optionally attempt to tackle early. Pretty much everything else available to you is best done before you beat the game. You won't be locked out of anything, at any point, from this point in the game forward. Not even after you beat the end boss.

Thank you very much!

You're actually locked out of fast travel for a fair chunk of the late game but once you hit the final dungeon (you'll know it when you get there), you can fast travel anywhere and the final side quests open up. So I wouldn't worry about it, and ofc, there is a "post-game" which is *mild spoiler*? really just you right in front of the door to the final boss which is a huge missed opportunity imo.

Lol, I didn't realize this. Because the way it was set up, my brain got the impression that those would go away post game, so I did a bit of grinding and managed to beat them before the final boss, and it ended up making that boss too easy by comparison. Oh well. XD
