I should probably rename this blog, ‘The Annual Empire’…
That being said, here’s a little idea I had while rereading the Zweihänder rulebook recently.
One of the rules issues that’s bothered me for years is how to run what Zweihänder calls “Secret Tests”. The classic example of this is the test to spot an ambush: it’s the kind of test the player needs to roll, but the very act of rolling tips the player off to what the PC is trying to achieve. Spotting whether an NPC is telling the truth is another example.
Zweihänder has a nice little solution, by having the player roll, but the GM doesn’t reveal the difficulty modifier: the player rolls, the GM describes the result, and in edge cases, at least, the player won’t know how far to trust the GM.
There are, inevitably, weaknesses to this method. It penalises near-successes, for example. But generally, I think it’s a pretty cool way to maintain suspense.
But another way to resolve these issues in a d100 system would be to make more use of the respective digits. I’m a fan of d100 precisely because it can do cool stuff with the various numbers it produces in a single roll (e.g. the d100, the result reversed, the two face digits – other possibilities exist, like the 2d10 sum; the d100 is super-flexible).
So maybe the GM sets a difficulty number from 1-10 to spot an ambush, avoid a guard, detect a lie, or the like, with higher being more difficult. In the case of a roll against an opponent, the base difficulty might be the tens digit of that opponent’s respective skill. So a guard with an awareness of 42 would set a base difficulty of 4, perhaps modified for weather, light, etc.
