Hi all, me and my son are very new and still trying to figure one all the icon meanings. Can anyone help with this? I get the dots/diamonds/stars. Is this something completely different.

Thank you!

Does anyone know what this locked trial modifier is and which nightmare strand unlocks it? Losing my mind, swear I’ve done them all multiple times but I’m still missing this one. (Using a general image so ignore the fact the others are locked).
Thanks!!
