problem creating EL ...

[RObiN-HoOD]

I have a party of 6 players levels rog3/ill2, clr5, Pal5, brn5, clr4 and ftr4 (~4.6).
I'm trying to understand how can I determine the EL of the
monsters/NPC that I can put then to fight.

I was thinking of 4 half-orcs Rgr4 and 1 orc Clr6 for support.

Is that okey?

According to Chapter 4 of the DMG, this would be Encounter Level 9.

Each of the Rangers has a CR of 4. Doubling the number of creatures with equal CR always raises the EL by 2, so:

1 Rgr 4 = EL 4
2 Rgr 4 = EL 6
4 Rgr 4 = EL 8

Adding the Cleric (CR 6) brings EL up to 9 (check out the "Mixed Pair" column on Table 4-1.

So, basically, the PCs are toast.
