Experience

Experience in DotA 2 is given by a unit on the enemy team that dies. Experience is used to level up, and it takes increasingly more experience to level up as a hero's level progresses.

A few important things about experience:


 * Experience is equally shared by all heroes in a 1200 range.
 * Hero kills outside of 1200 range will give experience to the killer.
 * Denying an allied unit does not grant experience to the ally.
 * Heroes take experience even after level 25, even though they cannot use it.
 * Building kills grant experience.
 * Summoned units(units created by spells or items) give 50% experience.

Leveling
Once a hero has acquired enough experience it will level up. When a hero levels, its stats gets increased (each hero's stats increase differently) and it gains a skill point. The skill point can be spent on any one of the hero's spells or to increase the hero's stats.

Below is a table that shows the experience required by Heroes to reach different levels and experience gained by killing heroes and units of a certain level:

Hero Kill Experience
Hero kill experience is split by the total number of allied heroes in 1200 range.

If L is the level of the killed hero:
 * 1 Hero is granted 120+20*L experience
 * 2 Heroes are granted 90+15*L experience
 * 3 Heroes are granted 30+7*L experience
 * 4 Heroes are granted 15+6*L experience
 * 5 Heroes are granted 10+5*L experience

Experience from a hero kill is 50% greater when Easy Mode is enabled.

Unit Kill Experience
Unit kill experience is split by the total number of allied heroes in 1200 range.

If L is the level of the killed unit:
 * 1 Hero is granted 120+20*L experience
 * 2 Heroes are granted 90+15*L experience
 * 3 Heroes are granted 30+7*L experience
 * 4 Heroes are granted 15+6*L experience
 * 5 Heroes are granted 10+5*L experience

Experience from a unit kill is 50% greater when Easy Mode is enabled, and 50% lower when the killed unit is summoned.

Denying
Denying occurs when a hero lands a killing blow on an allied creep or hero. Heroes can only target allied units if the creep or hero is under 25% health. Melee enemy heroes in 1000 range of the denied unit receive 36/n experience and ranged heroes receive 18/n experience, where n is the total number of enemy heroes within the 1000 range. Denying an allied unit prevents the opponents from earning gold.
