Final answer:
Beserker barbarians in D&D gain abilities like Frenzy, Mindless Rage, Intimidating Presence, and Retaliation, enhancing their combat prowess and resilience.
Step-by-step explanation:
Beserker barbarians, officially known as Berserkers, are a subclass of barbarians within the role-playing game Dungeons & Dragons, which could be discussed in the context of Advanced Placement (AP) courses if analyzing game design or exploring creative writing. They gain several abilities centered around their rage, which enhances their combat capabilities. At 3rd level, they gain the ability to go into a Frenzy when they rage, allowing them to make a single melee weapon attack as a bonus action on each of their turns while in frenzy. At 6th level, they gain Mindless Rage, which makes them immune to being charmed or frightened while raging. At 10th level, they are bestowed with Intimidating Presence, allowing them to frighten an adversary. Finally, at 14th level, they receive Retaliation, which permits them to make a melee attack in response to taking damage from a creature within reach.
