Raid Challenges?

[Some Idiot]

Raids have challenges you can do to increase your chance of getting the exotic.

Do all challenges require that you be on master or are there some that can be done on normal? If some can be done on normal, is there a way to tell from their description?

Are all challenges on a weekly rotation so you can only do one specific challenge on any given week?

[EckyThump]

All raid challenges can be done on standard difficulty or on Master. There are no 'master only' challenges, but there IS a triumph for doing them all on master, so you'd miss that one (and any corresponding boost) if you only did them on standard difficulty.

The challenges are on a weekly rotation for the most recent raid only.
For legacy raids, the raids are on a seperate rotator, one per week has a pinnacle reward for completing it. Whichever one is up on that weekly rotator, will have all challenges active during that week.

master is always only required when it specifically says so
