All this is easily solved by a bonus in percentage to the resolve in cheks for each brother’s level. The higher the level – then higher the percentage. For example : for the second level +5% for the third +7 and so on (the figures are easily adjusted). Then higher the level and the base resolve, the greater the bonus. It is logical, normal, does not break the importance of the resolve and is easily programmed. Everything can be done, just would be a desire.
