The Experience System,

The Experience System, and Implications

How much experience do I need to reach level ?

Without any further delay, let's get down to business. Currently, the generally accepted formula for the experience required to attain a given level is:

Exp = Level^3 * R * C * H

where

Exp = experience required
Level = the level in question
R = Race Multiplier
C = Class Multiplier
H = the "Hell" Multiplier

Two important points need to be noted here. First, players begin the game at level 1, not 0. Secondly, when determining the "Hell" multiplier to be used, the correct one to choose is the multiplier for the level that has to be completed in order to reach the level in question, e.g. the multiplier for level 30 is used when calculating the experience required for level 31. So, in actuality, the equation more closely resembles the following:

Exp = (Level-1)^3 * R * C * (H for Level-1)

If this seems unclear, don't worry - I spent a lot of time pondering the formula before I really understood it. Here are the multipliers that are used:

Level	Multiplier	Race	Multiplier	Class	Multiplier
1-29	1.0	Barbarian	105	Bard	14
30-34	1.1	Dark Elf	100	Cleric	10
35-39	1.2	Dwarf	100	Druid	10
40-44	1.3	Erudite	100	Enchanter	11
45-50	1.4	Gnome	100	Magician	11
51	1.5*	Half Elf	100	Monk	10
52	1.6*	High Elf	100	Necromancer	11
53	1.7*	Halfling	95	Paladin	14
54	1.9*	Human	100	Ranger	14
55	2.0*	Iksar	120	Rogue	9.5
56	2.1*	Ogre	115	Shadow Knight	14
57	2.2*	Troll	120	Shaman	10
58	2.3*	Wood Elf	100	Warrior	9
59	2.5*			Wizard	11
60	2.6*

One of the outstanding features of the formula when combined with the multipliers above is that it puts certain Race/Class combinations at a significant disadvantage in terms of experience required to level. To illustrate this point, consider this comparison of the experience curves of the Halfling Warrior and the Troll ShadowKnight (two classes at opposite ends of the Multiplier spectrum):

There are some interesting points to note about the above graph:

Note first that these are exponential curves (as expected), and so become increasingly difficult (at a very accelerated rate) as one progresses in level.
In addition, note the "humps" in the curve which are particularly evident at levels 40 and 45 - it is no coincidence that these are "Hell" levels, and is a side-effect of the formula used, as Verant has stated in the past.
Thirdly, and perhaps most importantly, note that a Troll ShadowKnight requires fully twice as much experience as a Halfling Warrior in order to reach Level 60.
Finally, because all Race/Class xp curves are third-degree polynomials, they all share the same shape and characteristics,
and thus the average xp curve falls somewhere in the middle of the two curves above.
