I don't know if some people will be interested but i created an html page to have a more friendly way to create the "Upgrades Text" section of weapons.
You can import an existing "Upgrade Text" by pasting into the textarea at the bottom of the page and clicking the "▲ import" button.
Clicking on the tab name displays the stats for the given infusion.
You can enable / disable every tab by clicking on the tick / cross : use that for special upgrades with Titanite Scales or Twinkling Titanite.
When you're down, click on the "▼ export" button and copy/past the textarea into the "Upgrade Text" of the wiki.
You can access the sources on github by following this link: https://github.com/hexaheart/dark-souls-3-weapon-builder/ .
The project was under "unlicense" licence.
Feel free to do whatever you want with it and report any bug encountered.
