Thursday of the Castle Keeper: SIEGE this!


Hey SIEGE engine!  Looking for an easier way into the castle?  Next time try the damn drawbridge!

Presenting the DRAWBRIDGE Universal Action Resolution System©:
Rather than rolling either a 12 or an 18 on d20 to determine success, using the DRAWBRIDGE Universal Action Resolution System© you need to roll an 11 or higher on d20.* This applies to virtually everything you want to attempt**--even combat!  Since not all tasks are created equal, each action you attempt has a challenge level.  But to keep in the drawbridge theme, we'll call it the Bascule--combat Bascules are commonly referred to by the acronym AC.  Just like a real Bascule, which is the counterweight in the drawbridge, the Bascule in the DRAWBRIDGE Universal Action Resolution System© balances the difficulty of the task at hand with the likelihood of the character achieving success. Exceptionally easy tasks can be assigned a negative bascule.
How to use the DRAWBRIDGE Universal Action Resolution System©:
  1. Add the Bascule (or opponents AC in combat) to 11; this is your target number.  Roll this number or higher on a 20-sider to succeed.  
  2. Add ability bonuses/penalties, combat bonuses, and/or appropriate levels to die roll.  If the total equals or exceeds 11 + Bascule/AC, you did it!  Climb the wall/roll damage/take half damage/whatever.  Roll less than 11 and you get to roll up a new character while the rest of your party is left to the task of parsing out your belongings. 
Converting SIEGE Engine to the DRAWBRIDGE Universal Action Resolution System©: 
Combat: Subtract 10 from AC, add AC to 11 -- this is your target number.  Or, since AC in C&C is derived by adding all your armor bonuses to 10, you can just leave off adding 10 in the first place
Other: depending on the primeness of your attributes you will need to add either 1 (primed) or 7 (un-primed [ouch!]) to the appropriate Bascule.
Next week we'll discuss how to convert AD&D combat to the BARBICAN Combat Resolution System©, a subsidiary of DRAWBRIDGE, LLC and Dice-Chucker Productions.

*This represents a 50% chance of success for a normal--which is to say, not-cool--person.  It is also the minimum requirement for a 0-level human to hit AC10 (no armor) in AD&D; i.e. it is the bedrock upon which all combat is built.  Thac0 can suck itself raw.
**Assuming of course that the activity you are attempting has, in the Castle Keeper's sound opinion, a reasonable chance of failure.  It is up to the Castle Keeper and, to some extent, the players to decide when to use the DRAWBRIDGE Universal Action Resolution System© and when to just role-play the situation instead.
