How does the Mythic+ affix scaling algorithm work in World of Warcraft?

In my Mythic+ experience, the difficulty curve is achieved through two separate scales: one is the base stat values (mainly armor, resistances, and crit/haste, etc.) corresponding to the player's gear level, and the other is the "level multiplier" within the dungeon. For each increase in Mythic+ level, the system multiplies the enemy's health by a fixed coefficient (around 1.12–1.18), while the corresponding dungeon properties (such as damage, healing, and crowd control strength) also increase by the same multiplier. The dungeon's attribute multiplier does not grow linearly but follows a predefined exponential curve. This ensures that the difficulty increases relatively gently at low gear levels while rising more steeply at high gear levels, preventing players from feeling too comfortable even with top-tier gear. Blizzard also adjusts the base damage of specific enchants (such as Frostfire or Burning) with an independent adjustment table, ensuring that the damage ratio of the same enchant remains consistent across different difficulty levels. During my attempts at levels 15–19, I noticed that as the level increased, the enemy's health growth became more pronounced, while the enchant damage increase was relatively mild. This is exactly the rhythm the designers intended—letting players of all gear levels feel challenged. For lower-gear players, the increased health prolongs fights, while higher-gear players face higher burst damage. This balance keeps the system's difficulty progression smooth across all tiers.

When I first hit level 15 Mythic+ on Shadowlands, I realized the health and damage spikes weren’t just a straight line—Blizzard actually layers in a few variables. Each affix has its own base multiplier (e.g., Rotted adds about +30% damage, Sanguine converts health to damage), and those multipliers are then scaled by the dungeon’s overall level factor. The level factor itself comes from a curve that smooths the jump between keystone levels, so the increase from 14→15 is roughly the same as 15→16, but the affix contribution grows a bit faster at higher levels to keep the challenge consistent as gear improves. In practice, when I ran a 17-keystone with Grievous and Ruin, enemy health was roughly 2.8× the normal Mythic baseline, while damage was about 2.5×, which lined up with the numbers I’d seen in WoWHead’s data tables. What keeps the progression feeling “smooth” is the combination of a base health/damage curve and affix-specific scaling that both reference the player’s average item level for the week. Blizzard uses the weekly gear snapshot to tweak the overall multiplier, so a well-geared group will see a slightly higher health pool than a group with lower IL, but the relative difficulty of each affix stays constant. I’ve also noticed that the scaling caps at around level 23, after which the affix multipliers level off and the primary challenge becomes the time limit and the “force-kill” mechanics instead of raw damage. This layered approach explains why the difficulty curve feels consistent across the whole keystone range.
