Experience works as in Diablo II: monsters well below your level give less, so you level close to the monsters instead of racing ahead. Slain monsters leave experience gems to walk over; as an act's boss falls, the gems left on the field fly to you.
Monsters below you
| Your level above the monster | Experience you get |
|---|---|
| 5 or fewer | 100% |
| 6 | 81% |
| 7 | 62% |
| 8 | 43% |
| 9 | 24% |
| 10 or more | 5% |
A monster above your level gives D2's share too: from level 25, your level over its (Hell's Baal gives a level-80 hero 81%); under 25, less only once it stands 6 or more levels above you.
Levels
Experience to the next level grows with each level, by 10% more a level from 25 and again from 90. Past 70 you also receive less of each kill, as in D2, so level 99 is a long goal.
| Level | Experience to next | Share of each kill |
|---|---|---|
| 1 | 5 | 100% |
| 10 | 83 | 100% |
| 20 | 218 | 100% |
| 25 | 297 | 100% |
| 30 | 615 | 100% |
| 40 | 2,370 | 100% |
| 50 | 8,346 | 100% |
| 60 | 27,775 | 100% |
| 70 | 88,912 | 95.3% |
| 75 | 157,319 | 71.9% |
| 80 | 276,656 | 48.4% |
| 85 | 483,912 | 25.0% |
| 90 | 926,658 | 6.0% |
| 95 | 2,587,037 | 1.5% |
| 98 | 4,781,115 | 0.6% |
Monster levels
- On Normal, monsters' level rises with the act's clock. Champions stand 2 levels above their pack's, uniques 3.
- Named uniques meet your level, as in Resurrected's Terror Zones. On Nightmare and Hell act bosses do too, up to 5 levels above you.
- Terror tiers set monsters at 85 plus the tier, up to 99.
Losing experience
A death in a Terror tier costs 10% of the level's experience, never a level.
