Help with symbols

Hi everybody,

I'm trying to use MSE to make game aids for L5R 5th edition rpg (cards for Invocations, rituals, katas, shuji...).

The cards are "ok", but I'm having a hard time trying to use symbols.

I'm looking to have a symbol (see below) which would be used in a specific field (opportunities) but I couldn't make it work.

I tried to use the basic magic reps (symbols are working with them) but when I try to modify the script, I must be doing something wrong and I loose the access to the symbols...

I searched a long time for tutorials about this issue... with no joy so far.

The only thing I found was a way to change the images of the symbols, but nothing about making them available in the insert symbol menu in MSE for a new template without modifying the MtG ones.

A solution would be to make a script parsing a field a changing all "*" with an image, but I don't know how to call an image with a script. I tried to look into the script file but I couldn't find/understand it

Sorry if I missed a post talking about this, I didn't read the forum in depth.

Thanks for your help !
