Farming Azazel on different realm difficulty should give different amounts of materials

Whether you farm Azazel on lowest difficulty or Normal difficulty, the final reward is the same number of Tier 3 materials.If lower difficulty tier results in less Essence rewards at POIs, maybe boss-farming rewards should also be adjusted, e.g,

• 4 units for difficulty 1

• 5 units for difficulty 2 (Normal)

• 7 units for difficulty 3

• 10 units for difficulty 4
