You will have the chance to earn new weapons and armor through the raid. These sets will be +4 on the armor and weapon sets, with a chance at +5 legendary weapons from the raid.
Orr is there more to that?
If there is a hardmode for the new raid, why not mention that in the article?
Edit: Thanks Rickness:
Regarding hard mode, we are planning on giving out +6 armor and weapons, with a chance at a +7 Legendary weapon. There will be other drops too, we’ll talk more about those as we come closer to releasing that version of the raid.
This should be updated / mentioned in the article itself, imo
