Room 3 - Hour 1 - Turn 5 - Rounds 1, 2
Okay, the party's actions are as follows:
Lyhan wants to tumble past the kobolds to engage kobold #1 in mêlée.
Zajirlum wants to attack with his flail.
"Rooks" wants to make a 5' step in and attack.
Kel and Dagon both look for something to throw.
In an OD&D combat (as those of you who are familiar with it already know, I'm sure), everything has to happen in phases, in the following order: movement, shooting, casting, melee. So this is how it goes down.
First, Lyhan attempts to use Acrobatics to move past the line of kobolds. This is a Dex check (+2) against a trained skill (TN 11). Lyhan's roll [9, + 2 Dex] hits it exactly. He flips past the kobolds and moves 15' down the hallway. He is now engaged in mêlée with kobold #1.
Second, Dagon and Kel return to the cell and arm themselves with the remaining two sets of manacles that were on George's body. This is all they can do this round.
Zajirlum attacks kobold #3 with his improvised flail. His roll [10, + 2 mêlée attack] hits. The kobold takes 4 damage and drops to the ground, as good as dead.
Rooks makes a 5' adjustment and attacks kobold #2 with an open-hand strike. His attack roll is a natural 20 - a critical hit! The kobold takes 7 damage and dies instantly.
Round 2
Kobold #4 makes a 5' step forward and attacks Zajirlum with a fist. The kobold's attack roll of 4 is a miss.
Kobold #1 turns and punches at Lyhan. This kobold's attack of 17 hits. Lyhan takes 2 points of damage.
