Great drama is at the core of the Gaming Experience. The character’s can’t be fighting the destruction of the world every session (though that can be fun), but there is great fulfilment in the climatic scenes of a campaign or long term adventure. Every climax is not seen in terms of violence (though it is very common). The personal stories of PC’s and NPC’s should also have meaningful expression in adventure climaxes. Yet all Climaxes in a campaign have similarities.
World Packs are the ONLY WAY TO GO!
A certain type of demon cannot not be hit by ranged weapons or attacks. Attacks have to be made up close and personal for the damage to mean something. Ranged attacks are to impersonal.
Possibally a way to make the ranged attacks more meaningful would be to coat the arrow head or what not with the shooters blood. Of course, they'd better be a good shot, otherwise they're wasting arrows and already bleeding to boot.
Spells: wizards might have half or no effect, preist might work due to divine intention.
