WorldGuard Integration
No configuration toggle — WorldGuard support activates automatically whenever WorldGuard is installed and enabled. If it isn't present, every region-based rule below simply has no effect and AtomCombat runs on its world-level and server-wide defaults instead.
Combat Core
modules/combat-core.yml → knockback.regions lets you override the active knockback profile inside a specific WorldGuard region.
Combat Rules
modules/combat-rules.yml lets you override, per WorldGuard region:
pvp.regions— allow or deny PvP.keep-inventory.regions— force keep-inventory on death.keep-experience.regions— force keep-experience on death.
pvp.respect-worldguard-flag: true additionally lets a region's own built-in PVP flag deny PvP even where AtomCombat's own rule would allow it.
