Diplomacy
Description
Diplomacy reduces the cost of surrendering, and increases the chance of wandering monsters joining you. It also allows a hero to enter a Library of Enlightenment before reaching level 10.
Recommended for: Any Hero with gold to burn and lots of desirable neutral stacks in the vicinity.
Wandering Monsters
Whether wandering monsters join you or not also depends on the formation of your army. Your army belongs to one of the three groups:
a. has none of that kind of monster at all. b. has at least one of that kind of monster c. the number of that kind of monster in your army is strictly above 50%.
Case C has the best odds of the monsters joining. In all three cases, both upgraded or non-upgraded are counted.
Comments
Works excellent with Visions, and can easily be the skill that wins the game for you.
It goes without saying, but Diplomacy is especially useful to players who like racking up wandering monsters that match their armies. Cunning Necropolis heroes that somehow learned Diplomacy can also exploit it for free Skeletons (which is more efficient than fighting for them).
