The rpg amker engine is pretty limited in a lot of areas unfortunately so I most of the times need to make workaround or make scripts that allow more complex stuff or grab free to use plugins that add some more complex features.
There is not really a way to categorie enemis into such types unfortunately so the best solution I came up with is giving them complete immunity to teh status effect.
It works very good but as you can see it'sa lot of extra manual work to set things for every enemy so sometimes such overlookings happen but they are easy to fix once I cought wind of them most of the times.
