I was making a printout from dndbeyond.com for a magic item that I'm hoping to give out in the next session, and noticed something that I found a little odd.
For the item Wand of Wonder (dndbeyond link, physical DMG p. 212), there's a line where dndbeyond says "An object of the GM's choice", whereas the physical book says "An object of the DM's choice". That is, dndbeyond uses the term "GM" where the standard D&D term and the term used in the paper book is "DM".
I checked a couple other places and found the same pattern for Necklace of Prayer Beads (dndbeyond, DMG p. 182) as well as Ring of Spell Storing (dndbeyond, DMG p. 192), where online uses "GM" and the book uses "DM".
Since it's consistent, I'm assuming that it isn't some sort of editing error, but an intentional difference. And while it doesn't really affect anything, my curiosity is piqued: Why are they using different terms?
