Infliction skill on Ghost Type

Infliction is a Normal Skill Type
It deals damage on the opponent and also takes some damages.

Ghost type don't take physical damages. Therefore ghost type shouldn't take any damage in return after using infliction. However it reduces the life of the monster without showing in the display.

During a battle, my ghost type is using infliction. After a few uses, it will force you to switch monster even when your ghost type monster's life is full. Next min, it is dead:(

What? Are you sure? I was told kamikaze doesn't effect ghost ... Infliction should be same thing... Maybe a bug?

Yup, I did a few tries, infliction deals "invisible" damage back to the user although it doesn't show on the display.

I think that might be a bug.
As far as I know, Ghost types can use moves, like Kamikaze and Infliction, and not get hurt by the recoil.
Hopefully, it'll be solved in the next update.
This is one of the few things I like about Ghost types, seeing as most are mediocre (compared to the over-used monsters), at the moment.
