One ancillary benefit of naming the new game the Brockport Campaign is that the names of my three active campaigns follow an easy-to-memorize A - B - C pattern:
A = Arandish Campaign (commenced 1/18/2010 in Eugene, OR, now plays over Skype)
B = Brockport Campaign (commences 12/4/2011, plays live in Brockport, NY)
C = ConstantCon, Tales From The Hotel Kaladarian (plays in HELL)
At any rate, here are the House Rules I plan* to use for the Brockport Campaign:
Our campaign shall obey the Labyrinth Lord Core Rules plus:
Shields Shall Be Splintered!
Shields provide the usual +1 bonus to AC. However, they may also be used to "soak" damage from a single attack, thereby reducing damage to zero. Soaking damage destroys the shield.
Shields may also be used against any attack that allows a save for half damage, such as a fireball or dragon's breath. In that case, the shield is destroyed, as above, and the save is considered automatically successful, thereby guaranteeing half damage.
For magical shields, each +1 enchantment bonus gives a 10% chance of surviving a damage soak.
Multiple-Turn Searching for Secret Doors Allowed
This deviates from the "one try only" rule as printed in LL p. 45.
Critical Hits and Fumbles
Any time a player rolls a natural ‘20’ on a to hit roll, it is a critical hit. Damage is doubled.
Likewise, if a player rolls a natural ‘1’ on a to hit roll, it is considered a critical failure or fumble. Typically, this means the combatant hurts himself, drops his weapon, breaks his weapon, or just plain falls down – Labyrinth Lord's discretion.
[EDIT: I removed "The D30 Rule."]
* Note: I anticipate having some veteran players onboard -- I know at least two of my probable attendees have played D&D 3.5 and/or D&D IV at any rate -- so plan to spend a wee bit of time at the top of the first session discussing these house rules and making sure nobody has any strong objections or intriguing suggestions. For myself, I am really hoping to stick to Race-As-Class and 3d6 in order, for part of my mission here is to introduce these folks to the mechanics and feel of old-school play. I want the whole thing to be as Moldvay-ish as possible. So I will resist adding AEC classes as best I can; but I do not want to ruin anybody else's good time either, so we'll see what happens. I am easily negotiated with.
