Some of the notable things in the patch:
- Savage begins for the first Dawntrail raid tier
- New master recipes for crafters
- New craftable gear for DoW/DoM
- Treasure portals have been added
- Tomestones of Heliometry have been added with a weekly cap of 450
From what I understand, they had a debuff they had to maintain on the boss but also not overcap. That was removed and replaced with a generic damage buff to your next few attacks or some such.
Not a viper player myself so don’t have the specific names or anything.
