Blocks like Glowstone don't have a specific tool, so you can't use the wand to break these in survival, but other blocks like that ex. Glass break just fine.

you can add any block not tool specific to wands.json so it can be broken with pickaxe or other vanilla tools, you can also deny a spcific block in str_denied
