Mechanics Question: Fear Immunity

[7thGate]

Does anyone know if there's a level-based blanket fear immunity at some point, like 56+ for stuns? Or do things have to actually be flagged fear immune to be immune to fear?

I found the immunity field in the spell data, it looks like fear spells are immune for > level 52, stuns > 55. Blinds don't have an entry in that field, which is interesting.
