I understand that a creature's CR is determines that it would be a chalenge for four PCs of that level. If you are using more than one creature then two of that creature are equal to the CR +2. So... how do you handle more than two creatures?

Also, with NPCs with character levels, do you just divide their HD by 4 to find their CR? For my specific situation what level would a sorcerer be to be ECL 4.

As long as the base creature was only a 1 HD creature, then it'd be Sor 4. The NPCs character lv will(as long as you keep things simple) be the NPC's CR.

As far as the adding mulitple CRs togther there's a nice encouter calculator here on the DND site.

edit: I'm at work so I couldn't go hunting for this right away.

A CR 3 isn't a good fight for a 3rd level party. It is a fight that will take out about 20% of their dayly resource. This is the CR meaning

- Every time you double the creature your encounter level go up by 2

Thus
One CR 3 creature is an EL 3
Two CR 3 creatures is an EL 5
Four CR 3 creatures is an EL 7
And so on

- To add 1 to an EL you can simply add a creatures with total ECL equal two point less than the ECL

Thus
One CR 6 creature is an EL 6
If you need an EL 7, you can add a CR 4 creature or two CR 2 creature


Here you are a very good encounter calculator, that don't give only the EL of an encounter, but give you the XP per character (basing on their level) and the value of the treasure supposed

This is the CR meaningWell, an EL 3 encounter is supposed to be a "good fight" for a 3rd level party, by which they mean a fight that the PCs should win without casualties but will take a little effort.

A "fair fight" (both sides equally likely to win) is typically EL level+4 or level+5. The PCs could likely lose, and are almost certain to have some casualties.
Every time you double the creature your encounter level go up by 2Agreed. Except for ELs of 1 or below, where you just multiply until you reach EL 2.

Beyond that, just aggregate from the bottom up.
EL X + EL X = EL X+2
EL X + EL X-2 = EL X+1
EL X + EL X-1 = somewhere between EL X+2 and EL X+1

Exact numbers don't matter; it's just a guideline. You still award XP based on CR.

+5 isn't fair but overwhelming, if the characters are created with 28 point buy or equally power
Immagine four 3rd level characters against
- One 5th level boss
- One ogre
- One 3rd level cleric
- One 3rd level wizard
- One 3rd level fithter
This is a EL = 8 and it's too hard for a 3rd level party
Consider the a four character party is a "PARTY LEVEL +4"
Four 3rd level character are an EL = 7
Thus an EL +4 is an encounter that make both sides win with equal possibility (they're the same parties)
