Re: Temple Ruins Near Luskan
Probably 10'. If you stand within 5' of the threshold, you have 3/4 cover, but can't see the plant. If you step into the room, it can attack without cover, but see it, if you step another 5' beyond that, you are out of range of the vine (probably).
OK, you sneak into the room, following the example of your spider (I rolled). You saw it start to stir and went still and then moved very slowly. You get the feeling that it's senses aren't based on sight and that you being invisible isn't as important as the fact that you are at the edge of it's reach and that it has already been hassled a lot.
How far do you go into the room in a stealthy crawl?
