Advancement Systems: Levels, XP, and Milestones

Quick Answer: Beginners should start with milestone advancement, especially in story-focused games like D&D 5e. It’s simpler than tracking XP and keeps the focus on the narrative. Levels and skill-based systems can be rewarding too, but come with more complexity.

Advancement systems determine how your character grows stronger, gains new abilities, or progresses through the story in a tabletop RPG. The three most common methods are level-based (like Dungeons & Dragons), skill-based (like Call of Cthulhu), and milestone-based (often used in story-driven games). Each has pros and cons, and some work better for certain play styles.

What Advancement Means in TTRPGs

Advancement is how your character improves over time. In most games, this means becoming stronger, smarter, or more skilled, but it can also mean gaining influence, wealth, or story progression. Unlike video games, where progression is often automatic, TTRPGs let the group decide how fast or slow advancement happens.

A good advancement system keeps players engaged by giving them goals to work toward. For example, earning enough XP to reach the next level or completing a major story arc. Bad systems feel arbitrary, too slow, or too fast—leaving players bored or overwhelmed. The right pace depends on your group’s preferences.

Advancement isn’t just about numbers. In some games, like Vampire: The Masquerade, your character’s personal growth (or corruption) is as important as raw power. Even in combat-heavy games, advancement can reflect story events—like a fighter learning new techniques after training with a master.

Level-Based Advancement (D&D Style)

Level-based systems are the most structured. Your character gains levels by earning experience points (XP), usually from defeating enemies, completing quests, or overcoming challenges. Each level unlocks new abilities, higher stats, or other improvements. Dungeons & Dragons and Pathfinder use this system.

XP is typically awarded after each session or encounter. For example, defeating a monster might give 200 XP, while solving a puzzle could give 50 XP. The GM tallies these rewards, and when you hit a threshold (e.g., 2,000 XP for Level 2), you level up. Some GMs skip tracking exact XP and just level up the party after a few sessions.

Levels create clear milestones, which can be satisfying for players who like measurable progress. However, tracking XP can feel like bookkeeping, and some players dislike how combat-heavy games often reward XP mostly for fighting. Variants exist—some DMs give equal XP for non-combat solutions to avoid this issue.

The downside? Levels can feel “gamey” and disconnected from the story. If your party levels up after killing goblins but ignores a major plot hook, it might seem odd that they grow stronger without engaging with the narrative. Some groups prefer milestone leveling (covered later) to fix this.

Skill-Based Advancement

Skill-based systems focus on improving specific abilities through use. Instead of gaining levels, your character gets better at skills they practice frequently. Call of Cthulhu, RuneQuest, and many “generic” systems like GURPS use this approach.

For example, if your character uses Lockpicking often, the GM might let you roll to improve it at the end of a session. In Call of Cthulhu, you mark skills you’ve used successfully, then later roll to see if they improve. This feels more organic—your character grows based on what they actually do.

This system works well for realism-focused or low-power games. If your group prefers storytelling over combat, skill-based advancement avoids forcing fights just to earn XP. It also lets characters specialize naturally—a detective who constantly investigates crime scenes will become a better investigator over time.

The drawback? Progress can feel slow or random. If your character rarely uses a key skill (like Swimming in a desert campaign), they might never improve it. Some players also dislike the lack of big “power spikes” that levels provide. It’s less satisfying for those who enjoy dramatic upgrades.

Milestone and Narrative Advancement

Milestone advancement ignores XP entirely. Instead, the GM decides when the group levels up or improves—usually after completing major story arcs, defeating a boss, or reaching a turning point. Many modern games, including some D&D campaigns, use this method.

For example, the party might level up after escaping a dungeon, rescuing a kidnapped ally, or uncovering a villain’s plot. The GM doesn’t track individual rewards; progression is tied to the story. This works well for narrative-driven games where combat isn’t the focus.

Milestones reduce bookkeeping and keep the spotlight on the story. Players don’t feel pressured to hunt for XP or take unnecessary fights. It also lets the GM balance pacing—if the party is struggling, they can delay advancement; if they’re breezing through challenges, the GM can speed it up.

The downside? Some players miss the tangible rewards of XP or skill checks. Without clear rules for advancement, milestones can feel arbitrary if the GM isn’t consistent. It also requires trust—players need to believe the GM won’t hold back advancement unfairly.

Which System Fits Your Play Style

Choose level-based advancement if your group enjoys clear rules, measurable progress, and “gamey” elements. It’s great for combat-heavy campaigns or players who like optimizing characters. Just be aware that tracking XP can feel like homework, and it may push players toward combat over other solutions.

Skill-based systems suit groups that prefer realism, organic growth, and low-power settings. If your game focuses on investigation, social intrigue, or survival, this method keeps advancement tied to actual character actions. Avoid it if your players love big power jumps or dislike randomness.

Milestone advancement is ideal for story-focused groups or new GMs who want to simplify bookkeeping. It works best when the GM is comfortable adjusting pacing on the fly. Avoid it if your players distrust GM fiat or crave constant small rewards.

No system is perfect—you can mix elements. For example, use milestones for levels but let players improve skills through use. Talk with your group about what feels rewarding, and don’t be afraid to tweak the rules to fit your campaign.
