If I don't have the monster, I can't use itSo what. That's meaningless.
I almost never see Slaadi ran. Just referenced.No in my experience. I've used and been in games where they have been used quite often. I've also seen them mentioned here a fair amount
Again. I almost never see modrons ran outside of WOTC IP washing or random forced quirkiness.Inevitables, in my experience yes. Modrons are popular from what I've seen on forums. I personally don't like them because walking shapes are too silly. However, a lot of folks online like them and talk about the Great Modron Race as a good thing.
They have distinguishable differences.False. They have distinct differences. They are no more barely distinguishable outside of a heavy RP session than any other alignment
Again my point is until you are heavily roleplaying, the differences don't really come up.
Organized crime is far more common than either one of those in my experience. Thieves guilds are all over the place.
Must be my luck.
I haven't run into a LE organized crime ring as a player in decades. It's more often me as a DM and the situation surpassing simple LE alignment.
