Dungeons & Dragons 5th Edition - Now your playing with Playtests!

[Conundrum]

Is it a undisclosed class feature? Is it a typo? How do you playtest if you don't know the mechanics behind the class?

For now, you take it in good faith that the math is sound and you test what they've given you. Otherwise they'd have to release the entire game system in one go, and they're obviously not ready to do that yet, but they require feedback on what IS done already.

The fact that there are 7 or so spells that require a saving throw but all of them are against con, wis or dex. They could at least include one example that is not.

Unless there aren't any that target the other saves. Which, judging by some of the responses to the "ability scores as saves" mechanic in this thread, might not be such a bad thing.

Later they say something like this: "There are tasks that some characters can perform automatically while other characters have no chance of doing" with the example of a boulder in front of a cave given.

Perhaps they're reintroducing a take-10 mechanic when faced with no strict time pressure. This would change your math significantly, though perhaps not enough. The other possibility is that, when they reveal the entire skill system, this statement will be something to do with trained/untrained skills.
