I was reading a
solid post by Trollish Delver, a blog I am sorry I just found, and it inspired me (thanks, Scott!) to write a new post in the Misunderstood and Improperly Played series, although I fear a better titled might be Forgotten About and Never Used.
Scott makes some good points in his post which I will
not sum up - go read his stuff! The link is in the first sentence and it is a great, quick read and you'll like his blog!
When I have new players being introduced to the game I often use weak undead for the second or third encounter: everyone knows they should be destroyed, so no moral qualms, and there is a reason they fight to the death. But immediately after that? As soon as they get the upper hand I have monsters try to surrender.
I also use the reaction roll. You do, too, right? I mean, here is the quote from the DMG,
"Any intelligent creature which can be conversed with will react in some way to the character that is speaking Reaction is determined by rolling percentile dice, adjusting the score for charisma...."
The section on generating NPCs has a chart showing how their various personality traits affect their reaction rolls. And the section on random encounters also discusses reaction rolls (which I will cover later).
In short,
1e assumes the DM rolls reaction checks with every encounter he did not explicitly set a reaction for. Walking through the briars and encounter a few men? Roll a reaction. In a dungeon and burst in on a group of dwarves? Roll a reaction. Bump into an ogre? Roll a reaction. Cast a
Speak with Animals and talk to a cow? Roll a reaction. Gnome is asking the badger for direction? Cast
Speak with Dead?
You get the idea.
