What? Am I about to walk back everything I just said about infravision in my previous post? Am I about to engage in rambling hypocrisy? Nope. I still prefer to run D&D games without infravision as a character ability for demihumans like dwarves and elves. Nevertheless, I wasn’t being completely straightforward about infravision in OD&D. I didn’t lie, however. Infravision doesn’t show up, at least directly, as a demihuman ability in the three original booklets. However, a case can be made that demihumans were understood to possess infravision even in the three original D&D booklets. One just needs to refer to Chainmail.
