But this is not SimDungeon. What works at the table has to be considered, unless this is a purely on-paper exercise, like so many oWoD discussions used to be.Sepulchrave II said:But there will always come a point where a PC rogue can outsneak a town guard, it's just a question of when.
In the kind of low magic vanilla I'm suggesting, a 5th-level rogue is not a common, low level occurrence - he is literally a 1 in 12,800 character.
That fifth level rogue will show up early in any campaign, at which point, he might as well have a wand of suggestion where no one is able to beat his saving throw. That's fun for an adventure or two, but very quickly, that becomes very, very boring.
I would push the "guaranteed success" threshold in a campaign much closer to name level.
