A question a week, answer the following week, until I get bored or forget. All questions from the 2ed AD&D Players Handbook, Dungeon Masters Guide, Monstrous Compendium Volume I, and Monstrous Compendium Volume II. Even setting aside 2ed is one of my least favorites, most the questions are troll piss. Rule math minutiae. Aspects of 2ed I find too stupid to endure. Quite a few that are common knowledge to any player these days. Mostly in regards to iconic monsters that were relatively new and unknown back in 1991.
First up last week's answer; A spell that produces matter or items from some other place (such as Evard's Black Tentacles) is a spell from what school of magic? PH, page 81 Conjuration / Summoning. [I'd say Conjuration. Summoning deals specifically with creatures. It's a subcategory of Conjuration. But, of course, such distinctions are what hour long, at the table, rules arguing are all about.]
Question (3rd lvl)
On a clear plain, how far can the silhouettes of characters at a campsite be seen due to the brightness of the fire?
[On the one hand, it's cool to provide information camping, fires, sight distance; that many modern people have no idea about. On the other, holy freaking OCD over detailed rule minutiae! There are OCD players who like the certitude of exact rules for everything. For me, 90% of 2ed and AD&D can be replaced with this DM advice on how to handle situation X "Fuck it, do whatever seems coolest / most fun."]
