Any skill which has a weapon type requirement, like:
data "Requirement" "RangedWeapon"
as is the case for Ricochet, will always require at least as much AP as it does to attack with your equipped weapon; that is why it always costs 5 or more with a crossbow.
If you have SkillData.txt located in Data\Public\Shared\Stats\Generated\Data it should use whatever changes you've made in game, regardless of any mods.
