Hello all new here I need some ideas for a new OD&D Blackmoor campaign

[Havard]

Hello Aldarron and Harvard,

I still trying to get an answer from either one of you about what does ATL and EL I believe iirc mean in the episodes? I have no clue. Is that 3.5 terminology? Maybe, I am guessing. I never played past 2nd Ed so I am not familiar with 3.5 or maybe its something new with these episodes only. I see it listed for the NPC's or monsters. Can someone kindly let me know. Thx kindly gents.

To be honest I was confused by this as well, even though I ran 3E/3.5E at the time. 

ATL is Average Table Level

EL I believe is Encounter Level. 

So, if the ATL is much lower than the EL, then the DM knows the party will have a tough fight ahead of him. Of course, noone has ever really managed to make a good system for gaging this sort of situations.
