HP Scaling is a property that many monsters possess, which was designed to ensure that fights take roughly the same time no matter the group size - mitigating/preventing steamrolling while still allowing for smaller groups to defeat them. If an enemy has HP Scaling, its HP will increase by a certain amount that increases with how many players are fighting it. HP Scaling will only start for additional players beyond the first one.
Different enemies will activate their scaling at different times in their lifetimes, sometimes upon spawning and sometimes after a delay. Enemies with HP Scaling will perform a player check roughly every 20 seconds, and readjust their scaling if needed. Readjustments in scaling will NOT affect the current percentage of health an enemy has. For example, an enemy has 100,000 base HP and 20% HP scaling (more details below). The enemy is weakened to 50% of its HP and there are 9 players in the area, so it has 130,000 out of 260,000 HP. Three players join (so there are now 12 players) and the enemy takes no more damage until it readjusts its HP scaling. After readjustment, it will now have 160,000 HP out of a total of 320,000 HP, which is still 50%.
Currently, two types of scaling exist: linear and adaptive.
Linear HP Scaling
This is the scaling used by the vast majority of enemies in the game. For every player beyond the first, a scaling enemy will increase its HP by a fixed percent of the original, increasing its maximum HP at a linear rate.
The fixed percent varies sometimes, but as a general rule of thumb, all enemies in the Realm scale at +10% Base HP per additional player in Realm, while all dungeon enemies scale with +20% Base HP per additional player in Dungeon. Some exceptions include the Permafrost Lord (20% scaling despite being a Realm enemy), Oryx the Mad God 2 / Shaitan the Advisor (30% scaling), and some of the Mad God Mayhem bosses. The linear scaling can be summarized in the following formula:
Scaled HP = b(1 - s + s*p)
where b is the base HP, s is the scaling factor (0.1, 0.2 or 0.3) and p is the number of players in the dungeon/realm.
Adaptive HP Scaling
Some enemies use a modified scaling system known as Adaptive Scaling, which uses a quadratic model rather than a linear one. Enemies with this type of scaling will gain comparatively less HP for the first couple of players, but the amount added per player will gradually increase as more players fight said enemy, causing the enemy’s HP to increase at an increasing (quadratic) rate. This means that small groups will not have to contend with scaling as severe as the usual model, but larger groups may have to deal with far higher HP values than linear scaling gave. Currently, the only enemies to use Adaptive Scaling are those in Oryx’s Sanctuary.
The Adaptive HP Scaling formula has currently been determined as:
Scaled HP = b + [0.09b + 0.02b(p-1)] + [0.09b + 0.02b(p-2)] + … + [0.09b+0.02b(p-p)]
which can be simplified to:
Scaled HP = b(0.91 + 0.08p + 0.01p2)
where b is the base HP, and p is the number of players in the dungeon. This indicates that an enemy will start at +11% HP scaling when there are two players, which is significantly lower than the usual 20-30% used by most dungeon enemies. The HP scaling factor will increase by 2% with each player until it reaches a theoretical maximum of +177% base HP for the 85th player. At 85 players, an enemy with adaptive scaling will reach a theoretical maximum HP of 7996% of the base value.
