The Encounter Reaction module represents the table on GMG p63. It offers you a random percentage roll but is editable should you wish to do your own rolling. If a party attempts to parley with an adversary, they can attempt some form of communication and this module determines the resulting reaction. Charisma scores of the party(ies) involved effect the roll. This module takes into account the highest Charisma score among the party members and inputs that. Again, editable.
