As it says on the tin, all ranger swords are now perfectly accurate, no other changes to damage or crit chance are included. Built with the XCOM2 SDK, so this mod is intelligently designed to find and replace only the edited lines in XComGameData_WeaponData.ini, and is thus perfectly compatible with other mods that effect the same file!
