Labyrinth Lord ascending AC

Both of the groups that I have been running Labyrinth Lord for have had trouble adjusting to the descending AC , and combat lookup table/thac0 system. To be honest after having played d20 for so long I find myself having trouble adapting as well. And so I went and converted Labyrinth Lord to an ascending AC system.

On another note but somewhat related I have decided that I don’t like using a screen while running my game. Switching to ascending AC gets rid of the problem of having to lookup attack values on a table but the issue of having to look up saving throws remains. I came up with a simple formula to approximate saving throws. In writing this post another, just as simple, idea for calculating saving throws came to me and I have added it to the document.

Combat sequence

* I continue to update this as I try different variations with my groups.

I use a combat sequence that differs slightly from the Labyrinth Lord one:

  1. Players declare any spellcasting.
  2. Initiative: 1d6 is rolled by each side; higher is better.
  3. The winner of initiative acts first. The Labyrinth Lord may check morale for monsters.
  4. Missile attacks occur.
  5. Spells are cast.
  6. Movement occurs.
  7. Melee combat occurs.
  8. Losing side performs steps 4 to 7.
  9. When every side has acted return to step 1.

Not a big difference but having missile attacks occur before spells provides a way for spell casters to have their spells interrupted.

Also, I prefer missile attacks and spells to occur before movement; it creates the opportunity for ranged weapon users to at least get one shot off before the fight comes to them.
