Difficulty

This is the difficulty level applied in the event. These will affect the reward content.

NORMAL
This is the basic difficulty level and is the default. Some more detailed information may specify a finer level of difficulty.

HEROIC
This is an end-content level difficulty. It requires the ability to understand and respond quickly to all situations. It is usually an extension of NORMAL, but there may be conditions and restrictions that apply only to HEROIC. On this difficulty level, items of ★1 or higher will basically drop for certain.
