I suggest adding a new stat, CHARISMA, to the existing ones like Strength, Wisdom, etc.
Charisma will affect persuasion and leadership, as well as the power of non-damaging spells, such as various shields, blessings, summons, etc.:D
P.S. I suggest assigning characteristics as in Heroes 5, with a certain probability for a specific castle.
