"Escape from Astigar's Lair" introduces a few notable conventions.
In terms of initiative, a d6 is rolled for the two-member party and another is rolled for the monsters. Highest roll goes first, as per group initiative in Moldvay (published in 1981).
Combat is also divided into sequences (missile fire/spells, movement, melee) similar to that in Moldvay (where movement precedes missile fire/spells and melee).
A system for critical hits and fumbles is also described (as in "The Dragon Crown").
Natural 20s result in double damage (for both players and monsters) and if a player rolls a natural 1, they must make a Dexterity check on a d20 or fumble (weapon takes 1 melee round to recover).
