Conversion
Conversion is an invasion mechanic that lets specific units or spells convert enemy peasants or units on successful invasions.
Standard Unit Conversion
Standard unit conversion is based on the units sent and the target's defensive power. Oversending beyond the units needed to break the target does not increase standard conversions.
UnitsCounted = min(UnitsSent, ceil(TargetDP / (UnitOP * OffensiveModifier)))
Conversions = floor(UnitsCounted * ConversionRate * ConversionMultiplier * RangeModifier)
At 75% range and above, RangeModifier is 1. Below 75% range, RangeModifier is:
1.25 * LandRatio^2
LandRatio is capped at 1. Conversion-rate spells and perks can modify ConversionMultiplier. Some spells and unit perks use special conversion or upgrade paths rather than this standard unit-conversion formula.
When multiple standard conversion unit types are sent, target DP is reduced after each unit type is counted, so later conversion types only count against remaining target DP.
