Ranged back up is used against on-target and on-self spells
Ranged back up uses the current target's equipped weapon to determine whether it should be used. When AI's opponent uses a spell or an enchanted item, ranged back up logic cannot properly figure out that the AI's target uses ranged combat and instead always gets used, making the ranged weapon the AI uses less effective due to the false need to retreat.
