Saving Throws: There is not much information in about the saving throw mechanics and chances of success/failure, in the manuals or guidebooks (or that I can find online). I have played all Infinity Engine Games, (pen and paper D&D 3 & 3.5 in college) and I THINK I have a pretty good grasp of 2nd Edition saving throws.

[1) Paralyzation, Poison, or Death Magic
2) Rod, Staff, or Wand
3) Petrification or Polymorph
4) Breath Weapon
5) Spell]

Is there ANY WAY to be able to figure out the odds of success or failure? Heck there is more information about THAC0 in the manuals!

It should be the same as in the other AD&D games. It'S explained here:

There's no place you can see them as far as I'm aware... who even knows if they're implemented in this game. I kind of doubt it since they probably could have crammed some shorthand on the View Character screen. And they display all your other stats.

I am not sure how rolls work for saves versus Fireball and so forth. Maybe they have them hidden, maybe there's some super-secret screen I haven't seen, or maybe they justifiably just use (21 - <yourLevel>) for the roll because hey saving throws are level-based anyway.

Regardless, I wouldn't worry about it.

The classic AD&D Goldbox games didn't show the saving throws anywhere either but used them nevertheless, the games were licensed and marketed using AD&D rules so there's no reason not to implement them since they don't hurt gameplay.

Ok, well if the Goldbox games had them in the background then it's likely Dark Sun did as well, but of course it used a different game engine. The main reason one would skip such a thing is to save on development and testing. I'm sure it's not terribly difficult to implement, just a table, but when the player can't see it corners like that get cut sometimes.

Thank you for your help
