Final answer:
Fast Movement is a feature that grants a 5th-level barbarian a 10-foot speed increase when not wearing heavy armor, improving tactical movement and agility in combat.
Step-by-step explanation:
Fast Movement is a feature granted to barbarians at the 5th level in the Dungeons & Dragons role-playing game. It enhances a barbarian's tactical mobility on the battlefield by increasing their base speed. When a barbarian is not wearing heavy armor, their speed is increased by 10 feet. This advantage allows barbarians to close distances quickly, either to charge adversaries or to assist allies. Moreover, maintaining a strategic position during combat becomes easier, which can be pivotal in encounters.
Players often utilize Fast Movement to navigate around obstacles or reach tactical vantage points that might otherwise be inaccessible within a single turn of movement. The benefit of speed becomes evident when evading enemy attacks or when you need to move swiftly to protect a vulnerable teammate. The agility and speed provided by Fast Movement accentuate the barbarian's role as a swift and formidable warrior on the field of battle.
