Character progression mechanic

Experience Level Penalty

You receive full experience while the monster level is inside your character's safe range. Outside that range, the level multiplier falls as the effective difference grows.

A level 80 character has a safe difference of 8, so monsters from level 72 through 88 are inside the full experience range. Normal monsters use the area level. Magic and Rare monsters are one level higher, and bosses are two levels higher.

How the calculation works

One monster kill
  1. Find the safe difference.Take 3 plus one for every 16 complete character levels.
  2. Compare character and monster levels.Subtract the safe difference from the absolute level gap. Values below zero become zero.
  3. Apply the multiplier.The current community reference uses ((level + 5) / (level + 5 + effective difference2.5))1.3.

Do not confuse the penalties

Separate rules

Level gap penalty

Reduces experience gained from a monster when its level is too far from your character level. This is the rule calculated above.

Death experience loss

Dying in an area accessed through a Map Device removes 10% of the experience required for the current level. It cannot lower your character level.

Character XP table

Check the exact experience required for every character level and calculate XP remaining for the next level.

Partying

Party size changes monster life, item quantity, loot allocation, and revival rules. The current checked PoE2 Partying source does not publish a party experience distribution formula.
