casting a spell with no cast msg, but displaying a desc msg with it

[Demosthenes]

as the title suggests, i'm trying to make a spell cast with no message displayed to either the player or the room (casted by certain rooms, so treated as if each user individually casts) which gives a desc message when the user checks their stats. as far as i can tell, there's no way to do it, since descmsg fires line 3 off as both a post-msg on casting and for the message on a stat check. is there something i'm missing, or is this impossible?

What kinda spell are you trying to make, is it a monster's spell? is it a spell a room casts? Is it area of effect or direct attack?

it's a spell cast by a room. the spell executes a textblock to check if the player has a certain item, and if so, renews a duration light spell on them. i want to make the duration light spell have a description message, but not echo that description message every second when the room renews it on the player.

Umm...i dont think you can get the stat message you could add a message:value command to the text block though.

how would that help? not sure i understand what you're saying here.
