How important are character elements in this game?

[BaconBankai]

I noticed all the characters have an element associated with them. Am I going to get to a point where I picked a bad character for a fight because its resistant to said element or something or where can I Play whatever character in any fight without issue?

It's not important at all. Late game you'll get a sigil called War Elemental that allows you to always hit at the superior element. They're basically just flavor that adds a little bonus dmg if you happen to hit an element you're good against.

It's nothing like the gacha game.

There's a sigil called war elemantal that makes all hits count as if the enemy is weak to your element so it doesn't really matter what you pick. Having said that the item is locked behind an absurd level of RNG.

Attacks that take advantage of an enemy's weakness deal 20% more damage, which is nice to have, but not so massive that you should consider building a team around it.

And you won't be punished for bringing the same element, like bringing an ice character to an encounter with an ice boss. You can still freeze it just fine.

In the main story, I'd say having elemental advantages over enemies is nice to have, but it's not necessarily needed. Once you reach end game, or more specifically Manic difficulty, you'll be able to obtain the War Elemental sigil, which makes all your attacks, regardless of what your main characters' elements are, do super effective damage (forgive my pokemon brain)

So for example, let's say you're using Lancelot, who is Water, but has the War Elemental sigil equipped, If you face an enemy who has a Wind weakeness, your Lacelot's attafks will do bonus damage as if he were a Wind character.

I don't think enemies have resistances, just a vulnerability. Which is what the icon next to enemy HP bars is. That's the element they're weak to.

I would suggest keeping the enemy's type in mind if you're having trouble in a fight, as the correct element gets a good damage boost. I'd say it matters most when it comes your team's big super team up attack. Since the character who starts the chain determines the type of the big explosion at the end you can end fights quicker if you use the right type of SBA to start the chain.

Overall though you can ignore elements throughout most of the game. You only really have to start optimizing your group in the final difficulty IF you want to skip boss phases and farm fights faster.

TL;DR: the right type of damage ends fights faster, which may make them easier.

You should really share the source of that sigil and how rare it is before praising it from the rooftops. It's SUPER rare and only drops from curios after you unlock the final difficulty. It's REALLY not something a new player needs to worry about.
