Elegant Rules (Forked From: Inconsistant/Arbitrary rules...)

[Heckler]

If you fall into lava you die. No save.

But what if I don't fall? What if I step into lava, or dive headfirst?

 

[Herschel]

1E/2E Area spells automatically hit, save for half (if you "ducked and covered"). No separate attack roles for each creature in area and no crits to have to calculate a different amount of damage with additional midifiers.

2E: THAC0 (besides being the greatest gaming term ever )

3E: Unified advancement chart

4E: already been covered by many.
