Amount Of Spell User Uses - How To Increment Initial Randomized Output

I created my own class and it basically randomizes the amount of 'spells' [magic] a user uses (range 1-5). I can't figure out how to increment the initial randomized output to make something like this :

User X : uses 2 spell.
User Y : uses 3 spells.

User X : uses 3 spells. (Taking the randomized 2 and increment by 1)
User Y : uses 4 spells. (Taking the randomized 3 and increment by 1)

My current setup looks like this : First one is the class I created and the second one is just how the output would look like. (seperate by +++++...)

My goal is to create a METHOD to increment it.

public class Spell {
// Max number of spells
private final int MAX_FACE_VALUE = 5;
// Current face value
private int faceValue;
// New instance of Spell
public Spell() {
faceValue = 1;

public class SpellOutput {
public static void main(String[] args) {
//Object creation
Spell spellCasterOne = new Spell();
Spell spellCasterTwo = new Spell();
Spell spellCasterThree = new Spell();
