I was wondering how much CDR do you need for 100% uptime of wraft
Not a whole lot if you’re using Obisidian Ring of the Zodiac.
If you are using boon passive about 34% with hardcast rends. If you are not hardcasting or not using boon you will need more. Obviously this is in push scenarios. For speeds you will want to stack as much as you can using crimson set since it is a direct damage multiplier.
