Mythic+ scoring comparison

This table shows the base score (from exactly timing a key) for each key level across seasons and expansions:

Blue cells with : bonus score starting at this level (generally because of an extra affix)
Green cells with : timing all dungeons at that level is sufficient for KSM (≥ 2000 points for all timed)

Scoring rules

Shadowlands Season 4 and Dragonflight Season 1 - 3 all use the same starting point, but with different bonus structures:

30 + (level × 5) + bonus

Dragonflight Season 4 uses a different starting point and bonus structure:

80 + (level × 7) + bonus

The War Within Season 1 uses a different starting point and bonus structure:

135 + (level × 15) + bonus

The War Within Season 2 uses a different starting point and bonus structure:

125 + (level × 15) + bonus

There are additional time-based scoring rules which apply bonuses or penalties to the base score. For example, a +3-chested +2 key (in TWW S2) grants 170.0 points, rather than 155.0 points.

Affix scoring (Shadowlands and Dragonflight only)

Shadowlands and Dragonflight take the best run for each dungeon for each of Fortified and Tyrannical weeks, and then calculate your overall dungeon score with:

dungeon_score = (higher_score × 1.5) + (lower_score ÷ 2)
