While trying to make builds and such, I noticed the resources online were lacking for just listing everything out. There is some incomplete stuff out there that will undoubtedly be better than this list when they are complete, but hopefully everyone finds this useful in the meantime or can use it to make better tools.

What this guide does is list out the Skills, Attributes, and Skill Trees as they appear in game exactly as written, along with a few notes here and there with my own observations. Some Skills and Attributes don't work properly or aren't very well explained. I've done my best to explain what doesn't work and how things do work but I haven't been able to test absolutely everything. So any help filling in the gaps or bringing up little known information would be appreciated.

I have not included the additional Skill Tree/Power Tree that can be unlocked later in the game for a variety of reasons. That may change in the future, but for not you'll have to unlock them to see them.

I hope everyone enjoys the guide and finds it helpful and please let me know if you have any questions or suggestions in the comments.

Some skills do not work as advertised and some I haven't been able to tell yet because I've not leveled the related skills high enough to know for sure one way or the other. If anyone can confirm any of the skills, please let me know.
