Hello again, I had this idea since I played the first time NWN campaign and as the people says is about traps, so what I want to suggest is to make traps an effective weapon inside the rogue arsenal by letting them be placed, used and retrieved to be resused.
The motivation are the following:
Traps are heavy (in number, you need some to kill a mid spawn),
occupy a lot of inventory (you need different kind and they don't stacks),
cost a lot (a single trap cost isn't high, but one is never enough),
a single trap is rarely a one hit kill device, most of the time the damage deal is very low (or 0).
So what I want to suggest is make the trap placed on the ground "exhausted" when triggered, after the use you can still retrieve them and replace them again, then repeat the operation over and over.
In this way you can literally build a good ambush scenario (both alone and in party) without spend a fortune everytime or have the inventory filled by traps.
That's it, let's discuss.
