The Sword of Laban is similar to Excalibur: it is a symbol of true kingship, and among those who know the sword's history, the possessor is alternately viewed as the true king, or a vile pretender to the high throne. Thus, anyone, not already a king, who presents this sword in a civilized area, where the sword would be recognized, has all of their reaction rolls adjusted upwards or downwards by at least two digits, by the DM, depending on who the sword is presented before.
When presented before commoners, make the 2d6 reaction roll, and any rolls of 7, or below, are adjusted downwards by two; any rolls of 8 or more are adjusted upwards by two.
If the Sword of Laban is presented before anyone in authority (town guards, clergy, guild masters, nobility, princes, etc.) adjust the 2d6 reaction roll down by two; a reaction roll of 10 becomes an 8, and so on.
The wielder can use her Charisma bonus to adjust the initial reaction roll.
Because the Sword is the symbol of true kingship, natural and modified reaction rolls of 12 or more cause the person so encountered to rally to the cause of the wielder, so long as the wielder takes efforts to care for and protect his new follower. Conversely, those persons for whom a natural or modified 2 or lower is rolled will believe the possessor is a vile pretender to the high throne, become violently opposed to the wielder, and will join with others who feel likewise.
The Sword of Laban is a reputed to be a vorpal blade, as well as having additional Demon and Giant slayer properties. It is not known to be an intelligent sword, and the DM is free to assign whatever attack and damage bonuses seem appropriate to the sword in the campaign.
