'''Diplomacy''' is a [[Skills|skill]] that gives heroes a chance to pay and recruit enemy neutral squads instead of fighting them, provided that their army is strong enough to intimidate them into doing so.
|subimage1=diplomacy_sub_larger_than_life.png
|subdesc1=Neutral squads view the hero's army as +25% more powerful than it is, increasing the chance that they will join or flee. This bonus is doubled if the hero knows [[Battlecraft]].
|subname2=Eloquence
From the game files (Core.zip — DB/diplomacy_info.json, the field/enum names in the game's IL2CPP metadata and others) it looks the the chance to join is affected by the strength ratio of the neutral stack against player stack. A join will happen, if the player's armystrength + modifiers > neutral stack's armystrength + aggression level.

|subname3=Folk Hero
Apart from the diplomacy skills, players' strength is affected by:
|subimage3=diplomacy_sub_folk_hero.png
* Troop count [9, 13, 21, 31, 44, 64, 150] per tier (hitpoints seem irrellevant here and the neutral stacks are valued higher per tier [25, 50, 75, 125, 225, 425, 1250])
|subdesc3=+50% Persuasion Power in Diplomacy with neutral squads from the hero's faction.
* Matching unit - an exact match applying a x3 modifier to troop count and a partial match (different upgrade path, but same unit) applying x2.
* Hero level (+200 per level, making a level 10 hero equivalent of aprox 64 tier 4 troops)
* Hero primary stats (+5 per point)
|subname4=Art of the Deal
Keep in mind that the map template may generate neutral squads that will never join or always join rendering the modifiers irrelevant.
|subimage4=diplomacy_sub_art_of_the_deal.png
Also, the modifiers may be changed at any point in balance patches - the above is based on version 0.80.24
|subdesc4=Neutral squads take –15% Gold to recruit. This bonus is doubled if the hero knows [[Economy]].
