Hey Doc
Not sure you still need the advice still. But I love your approach.
I myself use to prevent metagamers and rulelawyers my own rule-set and pilfer from whichever setting I like to create a unique blend to the pleasure of my players, who really love to explore something unique and never before seen.
They quickly learned that my orcs aren't the cannon-fodder they were used to from other games - and now the word orc, strikes fear in their hearts as it should have had from the beginning.
As to lore-based characters, they have a fair chance to gain and have this knowledge - at least what has been transmitted trough the ages.
Here I found the approach of the
Iron Kingdoms especially useful. They distinguish four levels of lore (Monsternomicon Vol. 1 page 208):
Common lore (about a subject/monster/place) is easy to find. This can be the name of a creature, what it is supposed to look like, or even peculations on its origin. Typically this comes in the form of a tall tale told by an old salt or a poorly written passage in an ancient bestiary. Common lore is usually just enough to give a rough idea of what adventurers may potentially face. A rare creature might not have any Common lore.
Uncommon bits of lore tend to be more specific and helpful. Examples are vague ideas of what sorts of powers a creature may possess, weaknesses it might have, or even the vagaries of where it might lair. Usually this lore comes in some concrete form. Old maps from the attics of dead adventurers or tomes and books written by half-mad scribes are good sources for this sort of lore. An extremely rare creature might not have any Common or Uncommon lore.
The realm of
Rare lore is the province of the damned. This information almost always comes from firsthand encounters, survivors of attacks, or observations made by hidden spies. Infernal tomes of summoning, a necromancer’s notebook, a rogue apprentice’s betrayal — these can all grant
Rare lore. This sort of information is specific and often directly useful. The specific powers of a creature or how to counter a special attack it makes are types of Rare lore that might save an adventurer’s bacon.
Obscure lore comes in many forms, such as fevered scrawling found on asylum walls, dredged up secrets from ancient writings, and the perturbing observations of otherworldly diagrams. Obscure lore isn’t always directly helpful — the problem with myths and ancient texts is that they often need to be interpreted. Still, Obscure lore can reveal the origins of a creature or its fatal flaws if the researcher is diligent.
This concept has proven very useful for my sort of campaigns and I hope it will help you too.
Let the dice roll and create the sort of adventure you and your players love most!
Good Gaming to you all!
