If I have multiples of the same % boosting module in a room (e.g., Suppressive Firebot 1, ), do I get the bonus from each individual module, from the boost total (e.g., three Suppressive Firebots 1, for a total boost of 45%), or only from one module?



Also, is there I way to see the effects of modules on my heroes when they enter the room? The character sheet doesn't give enough detail on things like this.

They do stack, yes.



To check the effect on a hero you'll have to open the character sheet outside the room, remember what you see, enter room and check the character sheet again.
