Just to simplify things, AA's and FC's are done the exact same way.  The only difference is in the acronyms.  If it moves to a match phase, then it is a SM not DM.  No contract is necessary for FC.  AA and FC room requirements (where you can do them, see 'Contested Territories' fall under the same category as DM and SM.  Mass FCs are allowed! 
 
Assassinations require a contract, approved by the forum.  Contracts will be discussed separately, this charter will focus on the mechanics of the attempt itself.  The following things will be grounds for invalidation and possibly further penalty.  Falsifying any relevant information, such as dice, enhancers, etc.  Log alteration, ejecting possible bodyguards.  Basically retarded OOC shit that messes up the attempt.
 
    Solo Attempt
 
In order to begin the attempt, you must obtain one line of IC, which legally is anything that is not in OOC brackets.  Assassinations can be done in any chat room, it doesn't matter if it is another forum.  Once the line of IC has been obtained, you can do your initial scroll which must include.  ::IC entrance:: ( Nemesis AA on [Target SN] by [Your SN].  Your dice.  Contract number.  AA reg number.  Any enhancers you have.  Time / date.  Target has 5 minutes to respond with dice, enhancers, BG or face auto death )
 
Begin the count down until the target has stated.  After this, instruct the target to roll 2d20 perception.  2 HP is necessary to see the target by default, which can be altered by enhancers.  Keep in mind, even if the target has +2 perception and the assassin is not using stealth, you still have to get at least 1 HP to see the assassin.
 
If the target fails perception, the AA continues.  Attack the target IC, then roll 2D of your dice.  If HTK is met, AA is successful and you can post your final and close the log.  If it is not, then the target has the choice to fight or flee.
 
If the target passes perception, they are given the option to fight or flee.  If they choose to flee, they must exit the room IC.
 
If the target chooses to fight, they must attack the assassin IC and roll 2D of their dice to attempt and meet the assassin's HTK.  If HTK is met, the assassin is killed and must post the final and close the log.  If it is not, then it moves to AA DM.
 
AA DM is simple.  Damage that was taken during the AA phase is carried over, and both participants fight to the death.  There is no honor strike.  Hit points are dice sides x 2.  This is regardless of mortality.  Regular dice are used at this point.
 
Mass Attempts
 
These are AA's involving more then two participants, whether it be bodyguards or a second assassin.  A bodyguard can only be claimed if they are listed in the AOL lifestream (websites don't count) of both the target and BG at the time of the attempt, and if they are present in the room when the AA begins.  It is not necessary for BG's to have IC entered the room.
 
The initial scroll is given.  If there is a second assassin, he must do his scroll after the first, and before the first assassin begins the count down for auto death.  The first assassin is responsible for all proctoring duties. 
 
Guild / clan, forum HC members may claim two BG's.  Anyone else may only claim one.  After the BG is claimed, if it is valid it moves to perception phase.  Target rolls first.  If perception fails, the BG attempts.  If this fails, if there is a second BG they attempt.  If there are two assassins, a perception roll is required for each of them.  2 from target, 2 from bg 1, etc.
 
If any of the defending party spots an assassin, it immediately moves to the fight or flee phase.  The target of the AA makes a choice.  If they choose to flee, IC exit the room.  If they choose to fight, attack the assassin that was spotted and roll 2D of your dice to attempt and reach HTK. 
 
If HTK is met and there was only one assassin, the attempt should be closed and the log sent in.  If there are two assassins, the one that has been killed is eliminated and it moves immediately to Mass AA DM, even if the second assassin was not spotted.
 
If none of the assassins were seen, they move in and attack the target in order, each rolling 2D to try and meet HTK aes a team.  If HTK is met, the target is dead and the attempt is over, because the assassination was performed with neither of the assassins being spotted.  If HTK is failed, it moves to the fight or flee phase.
 
When HTK is failed, the target may choose to IC exit the room or counterstrike the assassins.  If they choose to fight, they must perform two consecutive attacks, one for each assassin, using 2D to attempt to meet HTK.  Unless both assassins are killed, it moves to Mass AA DM.
 
Mass AA DM is basically a team death match where all involved participants fight to the death until only one team is standing.  Again, this is a simple matter.  Attack order is: assassin one, assassin two, target, bodyguard 1, bodyguard 2.   Hit points for each person are their dice sides x 2.  This is regardless of mortality.  Enhancers that were claimed in the initial phase may be used.
 
When closing the log, state the following information.  Time / date, result of the attempt and any deaths.  Do not state how long the dead people have to obtain a resurrections, because this is only applicable if the attempt is deemed valid.  If it is valid, that information will be on the validation slip; and the time period begins after the validation, not after the actual attempt.  This is so people don't waste time doing resurrections on invalid AA's.
