MP Drain dmg room

[Kampfer]

for the MP Drain dmg room we don't see any msg of what we feel.. not even some vital energy is running away from us.. nothing

when we are in a place and we receive dmg.. from evil in a good area.. a good in a evil area.. room filled with fire.. cold.. stunned.. they all have msg

I agree on that. Usually it's the air that does some physical damage to you. But what's causing the mp drain is not known, nor how you feel the drain.
