Surprise in Combat

Who's influencing me right now: Gary Gygax, Cyclopeatron

Here's a house rule from Mr. Gygax that I hadn't heard before.

    * 1d6 for surprise. 1=1 round. 2=2 rounds. 3 or more=no surprise.

 I would extend this rule for rangers:

    * 1d6 for surprise. 1=1 round. 2=2 rounds. 3=3 rounds. 4 or more=no surprise.

This looks like it would fit nicely into our houseruled initiative system.  The only hitch I can see is that I like to  sometimes give automatic surprise to the player who jumps the gun.  In that case I would roll it like so:

    * Non-Rangers: 1d2 for surprise. 1=1 round. 2=2 rounds.

    * Rangers: 1d3 for surprise. 1=1 round. 2=2 rounds. 3=3 rounds. 

And that should do it.
