Looking for help with my build.

Hi all.

New player. I have finally decided on a build for my Guardian Templar. I found one online that explains most of what I want and need and I have followed it as much as I can.

I am looking for some help on what gear I should be using. I do not know how to search for the rare equipment the Build Guider talks about so I don't know if there are relatively cheap uniques I could be using instead (cheap being 20 or less chaos for each item). I also do not know how to show you my gems and equipment that I'm using.

So, if someone could tell me how to link my gear and passive tree to this post and then I can give more information that would allow y'all to help me.

Here is a link to the guide I have been using.
