Older scenario's with larger groups - Silent Tide spoilers

[MaartenDF]

I played through #0-01 Silent Tide today for a group of six first level characters, and I came across a problem. All of the encounters were way too easy for my group of players.

I know the later scenarios were balanced for six players, and that they have notes on how to make it a bit easier if the group only counts four. The earlier scenarios were balanced for four characters, however, am I right?

Can I make the encounters a little bit more challenging? How much leeway do I have? I would hate for a character to die in an encounter that I did not run as written, but, well.. these characters were only level 1. If they had been level 2, the encounters would've been even easier.

Does it have something to do with the scenario being written for D&D 3.5?

Not much leeway at all. What you can do is use environment to hinder them, wherever environment is described but no penalties are given you can add the penalties.

No.

They've had too many problems with DMs making the challenge "more appropriate" and getting people killed.

If you're running an older scenario with a larger group either cut the table size down somehow or find something fun to do with the scenario that doesn't involve a hard combat challenge, because you won't get one.

What they said. We cant be adding anything to them or taking away from what is written. The only thing can do is learn everything the bad guys can do and play them smartly, or could divide into 2 tables of 3 players and NPC.
