Could someone point me to where in the AD&D DMG, it defines what a balanced encounter is?
There is no exact notation in the AD&D1 DMG on what a balanced
encounter is, to my knowledge. There is advice on balanced
games and
dungeons, and looking at the charts we can see how that would break down into an encounter.
AD&D promoted the concept that the DM should provide a "balanced" campaign (that is, not a killer game, nor a Monty Haul game)
Yes.
but then left it up to the DM as to how that was achieved.
Mostly, yes. There are guidelines/hints in the form of the charts for random dungeon generation. The
Fiend Folio and
Monster Manual II expand these charts. This is all an unfortunate, and poorly executed way of telling/helping DMs create balanced encounters.
When I go back and read some of my old
Dragon magazines, I find the designers (EGG, Mentzer, etc.) warning DMs not to screw up game balance by fiddling too much with the RAW. Gygax also gives this warning in the DMG. Unfortunately, I only find these articles and paragraphs later, after these kinds of threads.
In
Dragon #101, September 1985, Frank Mentzer has an charticle titled, "Plan it by the numbers, a system for tailoring challenges to the characters". In this he charts out, in detail, how to judge the challenge level of an encounter compared to the party of PCs. One small table in the article looks eerily similar to the chart in the D&D3 DMG.
Let's look at the encounters in
The Lost Caverns of Tsojcanth.
Gary Gygax said:
This module was designed for six to eight characters of 6th-8th level, although it can be challenging for characters as high as 10th level. However, if more than four 9th-10th level characters are used, monster encounters will have to be strengthened to balance the party's strength.
It should be noted, though, that the cover of the module says, "An adventure for character levels 6-10."
The original tournament scenario of this module had six characters:
Characters Levels
Half-elven fighter/magic-user/thief 4/4/5
Elven fighter/magic-user 4/9
Halfling thief 9
Human fighter 8
Human cleric 7
Dwarf fighter 6
Now, the encounters in the Lost Caverns:
First Level
Room 2: 20 stirges - Monster Level II says 5-15 stirges
Room 3: 1 clay golem - Monster Level VIII says 1 clay golem
Room 4: 8 mobats - Monster Level III says 1-8 mobats
Room 5: 1 lurker above - Monster Level VII says 1 lurker above
Room 6: 7 pech - Monster Level IV says 5-20 pechs
Room 7: 5 giant cave crickets - Monster Level I says 1-8 giant cave crickets
Room 8: 6 green slime - Monster Level VI says --- green slimes (?? what does "---" mean on the chart?)
Room 9: 4 trolls - Monster Level VI says 1-3 trolls
Room 10: 1,000 normal bats - Monster Level I says 10-100 normal bats - this is kind of a weird encounter - more of an environment than monster
Room 11: 16 cave morays - Monster Level III says 4-16 cave morays
Room 12: 2 formorian giants - Monster Level VII says 1-4 formorian giants
Roomo 14: 6 piercers - Monster Level II says 1-4 piercers
Room 14: giant snapping turtle - Monster Level ?? - can't find this (is 10 HD)
-- Geez, this is getting much longer than I expected -- nearly *every* room has a monster encounter.
Room 15: 2 cockatrices - Monster Level V says 1-2 cockatrices
Room 16: gorgimera - Monster Level VII says 1 gorgimera
Room 18: 4 dao - Monster Level VIII says 1 (10% chance of 2-5)
Room 20: 6 lacedon-ghasts - Monster Level IV says 1-4 ghasts
Room 21: 3 xorn - Monster Level VII says 1-3 xorn
Room 22: 1 marid - Monster Level IX says 1 marid (Note: this is not a combat encounter, it can be a non-encounter [the marid is in an enchanged sleep] or can help the PCs [if they dispel the magic and ask for aid])
I might do the second level of the dungeon at a later time.
So, on this first level of a dungeon for characters level 6-8/10, there are encounters:
Level I x1
Level II x2
Level III x2
Level IV x2
Level V x5
Level VI x1
Level VII x4
Level VIII x2
Some of these encounters are at the upper end of their numbers, but still, that's how the level system was designed.
