Hmm.. yes! In Golden Sun there are four elements: earth, fire, wind, and water.
These can also be called respectfully: venus, mars, jupiter, and mercury. Sometimes you'll hear water, sometimes you'll hear
mercury, but just remember that they're generally the same thing.
In either game, you will always have an earth, fire, wind, and water adept. One
of each. So your party is fairly balaced when you start out, although you don't get all four at the same time. You should
also take special care of those who can replenish HP or raise others. Anyone can use items, but it's sometimes best to rely
on magic to, let's say, revive because items like Water of Life are rare and are generally unbuyable in stores. You'll earn
them through doing good deeds or sometimes they'll pop in artifact shops in the weapon and armor shops. They shouldn't really
be used unless it's a huge emergency.
Each element does have their weaknesses, and this is usually expressed in the endings
of battle sentences. For example, let's say that Jenna casted an elemental spell against a human. All human enemies (usually
non-adepts) are weak against any elemental attacks. You'll see at the bottom something like this:
Okay, notice the ending after the word "damage". Because it was a super effective
attack, the sentence recieves three exclamation marks (!!!). You be careful when the enemy does this to you
and keep repeating if you do this to the enemy. Either raise defense or resistance if this does become a huge problem to you.
Next is a normal damage. It's pretty neutral so it's not too life threatening. You'll
know that the attack done by you or the enemy looks something like this:
This time damage is expressed with a single exclamation mark.
Next is resistance. You will see this often if you constantly use an element that's
not strong against the enemy's element. Examples include venus psynergy on an earth monster, water on a mercury monster, etc.
You'll see a sentence at the bottom that looks something like this:
So, it's good if you're going to be resisting a lot of attacks, but it's not good
if the enemy is resisting. This kind of attack has a single period at the end.
