The link above is a collection for 5eTools. It will include nearly all my homebrew for all my settings, at least non-spoiler stuff. Instructions for importing this into 5eTools are included in the link above. Just be sure to ignore or delete the sources that aren't relevant to you, again instructions in the link above.
Do be aware that homebrew items can always be changed at any time during play, WIP items are more likely to change.
