Descriptions and Story Building
Sense of Realization
Rucht Lilavivat
Remember, too, that horror is a sense of realization. It's that "oh crap" moment, when you put two and two together and you don't like the result. Like when you find out that the little girl you are trying to protect from the vampire is the vampire. Or when you realize that the whole town isn't being attacked by undead, but is populated by phantoms doomed to repeat the same events over and over.
Senses
Sunstar
Try to cover all the senses with your description. Sight isn't the only thing that scares people.
Spellcasting
Hell_Born
I know that Ravenloft is a low-magic setting, but eventually any party is going to run into magic, whether at the hands of an opponent or even at those of an arcanist ally (or party member). As Ravenloft is a setting where the "storytelling" style of play is the optimal one, cast spells should have a little more detail than "the Fireball explodes".
My question is this; how do you handle the "visuals" of magic? What do spells look like when they're cast? Is there any sort of "special effect" from a wizard (sorcerer, shadowcaster, whatever) as they begin to cast a spell? What do "generic" (+1 sword etc) magic items look like?
A personal idea on the matter is for the Shadowcaster, from Tome of Magic; the darkness seems "drawn" to the Shadowcaster- it doesn't actually move, or provide any concrete bonus, but in the eyes of the viewer the nearby patches of shadow seem to stretch and waver ever so slightly in his direction. When he prepares to cast, shadows and gloom coils and flows around him, shaping itself into an undulating umbral mass that silhouttes him. But I'm not too sure if that's suitable though....
Jester of the FoS
I like to describe the environment. A wind rustling papers despite the calmness a moment ago, odd scents and sounds, perhaps a trembling of the ground and dimming of the lights.

Well for necromancy spells- I usually have the speech of the caster grow far heavier than normal- seemingly slowed. This goes along with their hand movements slowing as well seeming to broil the air around them. Those watching might see shapes on the edge of their periphery or think they hear the voices of the damned leaking up from the ground. Only for the 'dark' necromantic spells- some of them I don't count as evil.
HuManBing
I heard a really good idea on the DnD Wizards forum for necromancy spells. The caster prepares his spell, and then whatever effects the spell would normally have, it takes effect on HIM first. His eyes seem to grow and his face seems to shrivel as his flesh turns a ghastly pallid grey... Then, with an inhuman effort, he wrenches the effects off of himself, and targets an enemy, sending the magic across as an unholy shadow....
Joël of the FoS
Cool idea, indeed. And it makes the PCs think twice before rummaging through the necromancer's spellbook!
Kottakinge
Try to describe spells which can advantage your players. A wizards who cast stoneskin or barksin have a visible effect so the warrior won't lose his time trying to put his sword in his stomach.
As spells are a rare thing they're spectacular. A fireball will explode in a screaming sound, putting fire to everything. The druid make a deep and long sound in order to call the thunder, the holy symbol of the priest shine in a bright halo and the wizards just put some disgusting things from his pouch to the air while singing a complex mantra.
Suspense
Maarten Delforge
One thing that worked especially well was this: Let your players think they're getting attacked, then don't let them be. For instance, in my game, my players passed the Rolling Bridge of Harmonia (in Kartakass) and I explained how some of the Gargoyles on the building seemed much more real than other ones. One of the players even saw one of them move, though he wasn't sure of it.
Now, when the players were on the road, at nighttime, during a full moon, I had them spot strange giant bird-like creatures flying past the moon. They were scared alright...
