Total XP to complete a level = L^3 * C * R * H
Where:
C = Class Multiplier
R = Race Multiplier
H = Hell Multiplier (based on level)
C=1.0 (For all classes now), R=1.2 (Iksar), H=1.2 (Levels 35-39)
Total XP to complete level 34 = 34^3 * 1.0 * 1.1 * 1.2 = 51,881 (Gain 4,444 exp from end of L33)
Total XP to complete level 35 = 35^3 * 1.0 * 1.2 * 1.2 = 61,740 (Gain 9,859 exp from end of L34)
Total XP to complete level 36 = 36^3 * 1.0 * 1.2 * 1.2 = 67,185 (Gain 5,445 exp from end of L35)
This article does not say how much exp one loses on death. But from the numbers above, if death is a fixed amount of exp, then it will appear as a higher % in level 36 than level 35 simply because you only have to earn 5,445 exp to ding instead of 9,859.
