Hi Bill, sorry for the misunderstanding.
First, you have to access your own campaign editor: direct.codecombat.com/editor/campaign/campaign-name
When the editor is loaded, there should be a list of levels on the left, scroll down and click the button. There should be a dropdown menu allowing you to select the level. (In this case, you’ll select your own level.)
Once you’ve selected your level, there should be another plus sign that allows you to add rewards, There are four options. Achievement, hero, item, level. In this case, you’ll select the
“rewards” and add the sword. If you are satisfied with the changes, please click the down arrow at the top right corner and click save. (Must be logged in as an admin to do this. )
If you have further questions, please feel free to ask.
