The balance between atmosphere and the ability to be able to see 5 foot in front of you is a difficult task to handle though but on reflection, and once you find enough of the darkened areas, perhaps it will be appreciated that being able to see better with the subsequently reduced atmosphere is a small price to pay as opposed to it's opposite where you get creamed and can't even see the monster that did you in.
Half of adventuring is being prepared for the adventure so stuff like carry a light source, food, water, healing kits/potions. You can easily fix the 5 foot sight with a portable light source or with a spell which any adventurer with half a brain would have. So I don't see how darkness can be too much of a problem. Exploring caves and dungeons should be challenge to the adventuring ability of someone as well as challenging their combat prowess. What is the point of an adventure without the adventure?
There's a cave full of spider on central near the river of darkness if I recall the map name well, it's in the sinister forest (where you find some vampires on top. and where the troll central is) That cave even with magical items emitting light, you won't be able to see past 5 feet in front of you. It's filled of spiders and snake. Go spend a few hours there, and then tell us how you liked it in this type of real time/turn based game. You will certainly understand a bit more what dorg is saying.
I would cast ultravision if I had a character strong enough to go there.
Anyways, a bit of a suggestion to the GMs if I may. There are Item effects that give off a low light source. Often in various colors too. Would it be possible to place those low light effects in various places in a cave/dungeon? For instance, various places along the walls to represent torch lights or scattered throughout a chamber and/or corridor like coulombs of light from holes in the ceiling. Though I imagine the later being difficult to keep with game time.
Could also consider actually removing the light sources from gear to make things like darkvision/ultravision etc more useful. Just a thought
Oh cool, let me know how next time im on the server with you cause all the various light sources on my gear annoys me
Yeah, the first thing Steel does when he gets new gear is to remove all the light sources. Nothing on his person glows. :p
