|Is the dude on the right supposed to be Ogre?|
For the life of me, I can't find an encounter area in this mod that matches that memory. Is this another case of the Donjon Maestro taking liberties or am I just misremembering things?
Anyway, the purpose of this here post is really to point out an encounter area comprised of a chasm with a bunch of stalagmites sticking up from the floor. One can cross the chasm, the module informs us, by leaping from stalagmite to stalagmite, but the text states that you have to
"roll equal to or less than [your] dexterity on 1d20 for each jump."
I pose this question to you dear readers: published in 1981, is this the first appearance of a roll-under ability check in a D&D product?
