If you have an empty granary and a negative crop production in a village, troops will start to starve there. Starved troops return the crop training cost of the unit / (100 * their crop consumption) crop to feed the remaining troops for a while, until the granary becomes empty again. Troops starve in a specific order, however Kingdoms and Legends have different rules.
Kingdoms distinguishes between five starvation classes.
- Foreign units, that support the starving village.
- Own units from other villages, that support the starving village.
- Own units from the starving village, that are trapped in some gaul's traps.
- Own units from the starving village, that are at home.
- Own units from the starving village, that aren't at home (e.g. reinforcing an oasis or moving troops).
Troops of the first class starve completely before troops of any other classes, i.e. troops of the 2nd-5th class can only starve if no troops of the first class exist. Analogously, no troops of the 3rd-5th class can only starve if no troops of the first or second class exist, and so on.
Within one class, the biggest troop compound starves first, counting by numbers, not by crop consumption. If e.g. one player sends 5000 phalanxes and another player sends 3000 druidriders, the phalanxes will starve first, if both compounds fit into the same class. Within one compound, the most common troop type starves first, again counted by numbers, not by crop consumption. If the compound to starve has 2000 phalanxes and 1500 druidriders, its phalanxes will starve first. In case of a tie, the "leftmost" unit will starve, e.g. phalanxes before swordsmen.
These rules are applied unit by unit.
- It doesn't matter whether troops come from the same kingdom, NAP, confed or an enemy. All are treated equally concerning starvation.
- Unlike in T:L, sending a hammer into a WW may lead to significant starvation losses, as it's most likely the biggest troop compound and will therefore starve first. At a usual 6-digit negative production this means a 4-digit loss of infantry units per hour.
- Starvation does not generate any reports, but starved troops are mentioned in the welcome screen.
