I'm sure there aren't many that require IMMEDIATE reaction, but without the knowledge of these things you won't even know what's happening.

Learning these in character will probably widely include dying to them and then scrolling up to figure out what happened.

I use things like this to pick up on these maladictions.

#high {%1 sags with exhaustion a moment, but quickly regains {its|her|his} vigor.$} {<faa>}

Or you could:

#sub {%1 sags with exhaustion a moment, but quickly regains {its|her|his} vigor.$} {%1 sags with exhaustion a moment, but quickly regains {its|her|his} vigor. < muscular lethargy >}

I'll check the script board.
