I just thought I would let people know as this has been a fairly popular portion of the Monster Advancer. The random encounter generator now lets you generate a number of creatures a given CR or generate an encounter at any level you specify (it does the # of creatures and distributions to approximate the EL you asked for)
It also lets you restrict either method by creature type or environment.
(I wouldn't currently recommend restricting too much just because we need to increase the sheer volume of monsters in the system but do what you like)
For example:
I want a 10th level EL of Goblinoids. The system generates a randomly selected group of creatures that are goblinoids (currently only bugbears and goblins I think). It decides to return the following:
Goblin Rogue4 (CR4)
Bugbear Rogue2 (CR4)
Goblin Bard4 (CR4)
Goblin Sorcerer4 (CR4)
Spellwarped, Fiendish Bugbear Cleric1 (CR3)
Vampire Goblin Monk1 (CR3)
Vampire Goblin Fighter1 (CR3)
Goblin Fighter5 (CR5)
4 CR 4 creatures, 3 CR 3 creatures and 1 CR 5 creature which adds up to about a 9.83 EL overall.
That's right...it will give back advanced monsters, creatures with class levels, creatures with templates, creatures with templates and class levels, creatures with advanced hit dice, class levels and templates...you name it. All while working out groups of creatures of all different group distributions from one creature to many--and keeping the Encounter Level fairly close to what you want.
I hope you like it and send me your feedback.
(I just generated a Half-fiend Spellwarped Drow Wizard 1, Druid 3)
Help 3.5 Thrive!
While I think this program is awesome and is the best DM tool for 3.5 and I hate to naysay it at all, but...
The encounter generator is doing one thing I wish it wouldn't. I asked for an EL 14 with giants and I got a bunch of trolls. Great! Trolls work. Thing is, all the trolls have levels in spellcasting classes that they can't benefit from. I have 2 druids and a cleric with Wisdoms of 9, a sorcerer with a Charisma of 6, a half-fiend sorcer with a Charisma of 8, and a ghostly bard with a Charisma of 10.
In concept, a bunch of troll druids and an infernal troll sorcerer and a ghost troll bard is an awesome encounter that I would have never thought of. As is though, they are trolls with a few extra hit points. I have no clue how you would go about fixing something like that, and otherwise I love the site.
Now, I have to work out this charismatic troll encounter.

The associated classes versus non-associated classes is being worked on as well as making sure that stats are readjusted to match up with the classes the creature is assigned. This should let your trolls end up with stats that would allow them to use classes they were assigned. This is already underway and after that gets released I will be adding in some ability to tweak stats (and perhaps a few other things) after the encounter generation (just in case things aren't quite what you want).
You sir, are a prince.
