When thunder going off i think it would be pretty neat if the thunderstorm got the hoards and such to actually just go towards the storm and potentially saving / murdering people if you between them and the storm
On a side note of this do storms actually hide sound you make if a thunder/lightning strikes at the same time as making your own noise?
Effectively yes, since monsters only keep track of the location of the loudest sound they’ve heard recently.
Ha nice 
Currently thunders don’t really make a sound, they just print the message.
But if they did, they would distract hordes.
