Or does anyone know a few good builds for someone who loves zero but has room to improve?
All your Zer0 build needs right here:
Check the pinned topic at the top of the Zer0 category for a list of many other useful Zer0-related resources.
How do I know which are using the community patch? So many skills were changed and rebalanced and it seems it would change the builds.
You won’t find much - or any - UCP action here. There are no dedicated character threads and most UCP users have taken their conversations to other locations ( presumably Steam, Discord and Reddit ).
I don’t know anyone on the forum at the moment who can answer UCP Zer0 questions, but there are lots of us that can help with vanilla.
