Claim
Claim is a casus belli in Crusader Kings III (claims). If the attacker wins: The claimant gains the contested Title. If the defender wins: The defender keeps the contested Title. The attacker loses their Claim. Declaring it costs piety and prestige. The war goal is worth 80% war score. Patch 1.20.0.3, from game/common/casus_belli_types/00_claim.txt.
