In the Dragon Quest 3 HD-2D Remake, both the Pilgrim and Mage classes are valuable and worth leveling up, but their utility and effectiveness depend on the specific needs of your party and the game’s progression. Here’s a detailed breakdown of each class:

### Pilgrim
– **Role**: The Pilgrim class is a support class that excels at healing and providing utility to the party. They have fairly decent Strength and Vitality, making them capable physical damage-dealers, although they are not as effective in this regard as other classes.
– **Abilities**: Pilgrims are primarily useful for their healing abilities, which can be crucial in maintaining the health of your party members. They also have some physical combat capabilities, although these are not their primary strengths.
– **Synergy**: Pilgrims pair well with classes like Soldier and Fighter, who may require healing after drawing the brunt of an enemy force’s attacks. This makes them a good addition to any party that needs consistent healing support.

### Mage
– **Role**: The Mage class is ideal for players looking to leverage powerful offensive magic. Mages excel at high-damage spells and can cast a number of spells without consuming MP, making them extremely valuable for a damage-focused party.
– **Abilities**: Mages are particularly useful for dealing elemental damage, which can be crucial in various combat situations. They are, however, let down by their low defense, making them more vulnerable to physical attacks.
– **Synergy**: Mages can complement other classes like Warriors, who lack reliable ways to deal elemental damage. This combination can make your party incredibly versatile in combat.

### When to Level Up
Both classes are worth leveling up, but it’s crucial to consider the following:

1. **Party Composition**: Ensure that your party composition is balanced. If you have a Warrior or Fighter who can handle physical damage, a Mage can provide the necessary magical support. Conversely, if your party is lacking in healing, a Pilgrim can fill that gap.

2. **Game Progression**: Leveling up both classes will help you adapt to different situations as the game progresses. For example, early in the game, a Mage might be more useful for dealing with early enemies, while a Pilgrim could be more valuable later on for maintaining party health during tougher battles.

3. **Multiclassing**: If you plan to multiclass your characters, it’s essential to level up both classes to a point where they can effectively contribute to your party’s overall strength. Multiclassing allows you to combine the abilities of different classes, creating incredibly powerful characters.

In summary, both the Pilgrim and Mage classes are worth leveling up, but their utility depends on the specific needs of your party and the game’s progression. A balanced party composition that includes both healing support (Pilgrim) and powerful magical offense (Mage) will be highly effective in overcoming the challenges of Dragon Quest 3 HD-2D Remake.
