This extension requires the use of "Fallout RPG - Halifax Core" to work. This extension will automate the increase in defense of players and enemies targeting each other on maps based on the difference in distance and the Range of the used Weapon for the attack, as well as increase difficulty of Reach range shots with non-Close Quarters ranged weapons, and also modify difficulty of hitting prone targets based on distance. This distance is based on the Grid-Based Gameplay created by e4g13 that has been adopted as a homebrew rule set by Ziggy8z (Creator of the Fallout RPG ruleset) for the Fallout RPG ruleset.
