Gain a Class Level Progression Guide
This section explains the progression route up to a pure Fighter gain a class level 12. The choice of feats and maneuvers significantly impacts the build's strength.
Gain a Class Level 1-4: Foundation Building Phase
- Gain a Class Level 1: Choose a fighting style. Since two-handed weapons are your focus, select "Great Weapon Fighting." This allows you to reroll a 1 or 2 on damage rolls, stabilizing your damage output.
- Gain a Class Level 2: Acquire the Fighter's iconic action, "Action Surge." This ability, allowing two actions in one turn, is the source of this build's burst damage.
- Gain a Class Level 3: Select the subclass "Battle Master." Simultaneously learn three maneuvers. The following three are essential:
- Precision Attack: The most crucial maneuver, offsetting the accuracy penalty of the later "Great Weapon Master" feat.
- Riposte: Allows you to counterattack using a reaction when an enemy misses an attack against you. It's a powerful maneuver combining offense and defense.
- Trip Attack: Allows you to knock an enemy prone. Melee attacks against a prone enemy gain advantage, making this very effective.
- Gain a Class Level 4: Acquire your first feat. Here, choose "Ability Improvement" and increase your "Strength" from 17 to 18. This improves accuracy and damage, stabilizing early-game combat.
Gain a Class Level 5-8: Damage Unleashed
- Gain a Class Level 5: Acquire the passive ability "Extra Attack." This allows you to make two attacks with one action. Combined with "Action Surge," you can make four attacks in a single turn.
- Gain a Class Level 6: Acquire your second feat. Learn "Great Weapon Master," the core of this build. It's a powerful feat that grants +10 damage dealt at the cost of a -5 penalty to attack rolls. Compensate for the reduced accuracy with the "Precision Attack" maneuver.
- Gain a Class Level 7: Learn two new maneuvers. "Disarming Attack" or "Commander's Strike," which allows you to move allies, will broaden your tactical options.
- Gain a Class Level 8: Acquire your third feat. Again, choose "Ability Improvement" to raise your "Strength" from 18 to 20. This makes your attacks even more powerful and accurate.
Gain a Class Level 9-12: Build Completion
- Gain a Class Level 9: Acquire the passive ability "Indomitable." When you fail a saving throw, you can reroll it.
- Gain a Class Level 10: Learn two more maneuvers. Expand your options according to the combat situation.
- Gain a Class Level 11: Acquire "Improved Extra Attack." The number of attacks per action increases to three! When combined with "Action Surge," you can unleash up to six attacks in a single turn, capable of instantly melting even boss-tier enemies.
- Gain a Class Level 12: Acquire your final feat. Here, choosing one of the following is recommended depending on your playstyle:
- Savage Attacker: Roll the damage dice for melee weapon attacks twice and use the higher result. This synergizes well with the "Great Weapon Fighting" style, significantly increasing expected damage output.
- Alert: Gain a +5 bonus to Initiative and cannot be surprised. This is highly effective if you want to consistently secure First Turn Advantage and reduce enemy numbers.
Combat Strategy and Recommended Equipment
Basic Strategy
The role of this build is simple. Utilize the high defense provided by heavy armor to stand on the front lines, absorbing enemy attacks while annihilating foes with overwhelming attacks and firepower.
- Group Combat: When facing multiple enemies, approach the most troublesome foes (such as casters or high-damage archers) and aim to quickly neutralize them with focused attacks.
- Boss Fights: As soon as combat begins, immediately activate "Action Surge." With "Great Weapon Master" enabled, unleash as many attacks as possible. If you can knock the boss prone with "Trip Attack," all subsequent attacks will have advantage, allowing you to deal damage unopposed.
- Maneuver Usage: If you're concerned about accuracy, use "Precision Attack." If enemy attacks are powerful, utilize "Disarming Attack" or "Riposte." Choosing the optimal maneuver for the situation is key to mastering the Battle Master.
Recommended Equipment
- Early-Game Weapon: The greatsword "Everburn Blade," dropped by Commander Zhalk encountered in the area after the tutorial, boasts exceptional performance for the early game.
- Mid-to-Late Game Equipment: If you are Githyanki, powerful race-specific greatswords exist. Beyond that, actively seek out magical greatswords or mauls that have effects to bolster attack rolls or damage.
- Armor: Equip heavy armor to maximize defensive capabilities. Particularly recommended are items that reduce incoming damage or increase movement speed.
