Beast Barbarian 8/Psi Warrior Fighter 3: A Guide to Building a Powerful Character (2014 Rules)

Hey guys, let's dive into a super fun character build for D&D 5e: the Beast Barbarian 8/Psi Warrior Fighter 3. This is a build that offers a fantastic blend of raw, untamed power and tactical versatility. We'll be using the 2014 rules, so get ready for some old-school goodness! If you're looking to create a character that can smash through enemies with brutal efficiency, while also having some neat tricks up their sleeve, then this is the build for you. We'll break down the character's strengths, weaknesses, and how to optimize your Ability Score Improvements (ASIs) and feats to make your character a force to be reckoned with. Let's get started, shall we?

Why This Build Works: The Synergy of Rage and Psionic Power

So, what makes this Beast Barbarian 8/Psi Warrior Fighter 3 build so effective? It's all about synergy. The Beast Barbarian brings the raw damage output and survivability, while the Psi Warrior Fighter adds tactical options and ranged capabilities. Imagine a character that can not only wade into the thick of combat and cleave through foes but also control the battlefield with telekinetic blasts or unleash devastating ranged attacks. This combination creates a truly dynamic and engaging playstyle. The core concept is simple: Maximize your damage output in melee combat, improve your survivability, and then add some tactical flexibility through the Psi Warrior abilities. It's a powerhouse that's always ready for a fight, no matter the circumstances. This build focuses on the early and mid-game, where you'll find the most success. It offers a satisfying progression, allowing you to feel impactful from the moment you start playing.

The Beast Barbarian's Fury: Unleashing the Inner Animal

The Beast Barbarian is, as the name suggests, all about embracing your inner beast. At level 3, you gain the Bestial Soul feature, allowing you to transform your rage into different forms: a bite attack, a claw attack, or a tail attack. These forms offer a range of offensive and defensive options. The bite attack gives you temporary hit points, the claw attack lets you make an extra attack, and the tail attack provides a reach option. The Beast Barbarian offers great damage potential and survivability due to its Rage feature. In Rage, you gain resistance to bludgeoning, piercing, and slashing damage, and add your rage damage bonus to your melee attacks. With eight levels in Barbarian, you also gain access to an extra attack, improved critical hits, and additional Rage features that enhances your ability to deal damage and survive in combat. This combination of raw power and resilience makes the Beast Barbarian a cornerstone of this build.

Psi Warrior's Tactical Advantage: Mind Over Matter

The Psi Warrior Fighter, on the other hand, adds a layer of tactical depth. At level 3, you gain access to the Psionic Power feature. This allows you to spend psionic energy to perform various actions, like telekinetic blasts, telekinetic movement, and protective field. These abilities allow you to control the battlefield, offering excellent utility. The Psi Warrior provides tactical options in combat, allowing the character to deal with both melee and ranged threats. Three levels in Fighter grants access to the Action Surge feature, enabling an additional action once per short rest. This can be used to unleash devastating combos. This combination provides both tactical options and improved resource management, making the character far more versatile. This is how the build achieves its flexibility.

Leveling Breakdown: A Step-by-Step Guide

Let's get into the specifics of how to level your character. We'll aim for Barbarian 8 first, as this gives the benefits of Rage and Extra Attack, then take three levels in Fighter for Psi Warrior and Action Surge.

Levels 1-8: Beast Barbarian. Focus on taking the Barbarian levels first. This gives you the core features of rage, the Bestial Soul feature, and the extra attack. Make sure to choose your Bestial Soul form depending on the encounter. If you need more damage, use the claws. If you need some extra healing, use the bite. If you're fighting creatures with reach, use the tail. Prioritize Strength and Constitution to maximize your damage output and survivability. At 4th level, take an ASI to improve your Strength and Constitution. At level 6, you will get the Brutal Critical feature, and level 7 will give you the Feral Instincts. At level 8, you'll have access to another ASI, which will further improve your core attributes.
Levels 9-11: Psi Warrior Fighter. Now, take three levels in Fighter. This gives you access to the Psi Warrior subclass, offering psionic powers. You'll gain access to the Action Surge, allowing for the potential of two actions in one turn. This is great for an increased damage output or use two psionic abilities in one turn. The Psi Warrior also provides the advantage of fighting at a range, which is critical for many fights. This will also give you second wind for some extra survivability.

ASIs and Feats: Maximizing Your Potential

Alright, let's talk about the important part, the Ability Score Improvements and feats. This is where you can really customize your character to fit your playstyle and optimize your build. Considering that your build can get both high damage and high utility, it is important to balance this with the ASI and Feats that can further optimize your build.

Prioritize Strength: This is your primary damage stat. You want to hit hard, so boost your Strength as much as possible. A high Strength score will give you a better chance to hit and deal more damage.
Boost Constitution: Next in importance is Constitution. This increases your hit points and helps you maintain concentration on spells if you choose to take any in the future. Surviving in combat is paramount, and a higher Constitution score will ensure that you can stay in the fight longer.
Dexterity: Dexterity will boost your Armor Class. The higher your AC is, the less often enemies will hit you. The higher your Dexterity, the better the AC. This stat also improves some saving throws.
Feats: You have the opportunity to take four feats, which can significantly enhance your character. I recommend that you use the following feats:
- Great Weapon Master (GWM): This is a must-have for any melee damage dealer. It allows you to make an attack with a -5 penalty to hit, but adds +10 damage. With your Rage bonus and high Strength, you'll have a good chance of hitting. This feat also allows you to make an additional attack as a bonus action when you score a critical hit or reduce a creature to 0 hit points. This is very good for dealing an amazing amount of damage.
- Fey Touched: This feat gives you +1 to Intelligence, Wisdom, or Charisma, and gives you access to the Misty Step and another 1st level spell of your choice. Misty Step is a great way to escape combat, or get the upper hand on your enemies. It can also be used to teleport behind an enemy, for example. This is important for a Barbarian. The extra spell is a good addition to your utility.
- Tough: This feat grants you +2 to your hit points, and increases your hit points by 2 for every level. This feat drastically increases your survivability. This will increase the length of time your character can last in battle. This will increase the potency of your character.
- Savage Attacker: This feat lets you reroll damage dice and take the higher roll. Since you will be attacking multiple times per round, this can increase your damage output considerably. It can be used to make sure you deal as much damage as possible.

Combat Tactics: Unleashing Your Inner Beast and Psi Warrior

Alright, guys, let's get into the fun part: combat tactics! This build is all about getting up close and personal and mixing it up with some tactical tricks. Here's a breakdown of how to use your abilities effectively.

Initiate with Rage: Before you charge into combat, activate your Rage. This grants you resistance to bludgeoning, piercing, and slashing damage, and it will increase your damage output. Choose the Bestial Soul form that best suits the situation.
Smash with Advantage: Use your attacks to smash through your foes. If you have a rogue in your party, try and make an attack with advantage to give the rogue a chance to deal sneak attack. This is where your high Strength and Great Weapon Master come into play. Your rage gives you damage, and Great Weapon Master gives you extra damage. This will give you the potential to deal a lot of damage very quickly.
Use Psi Warrior Abilities: When enemies are too far away, or when you need some utility, use your Psi Warrior abilities. If enemies are clustered, you can use Telekinetic Blast. Use your Protective Field to protect yourself or allies. Use Telekinetic Movement to move yourself or enemies to gain advantages. Your Action Surge allows you to use more abilities in one turn.
Action Surge for Maximum Impact: Use Action Surge to make an additional attack, or unleash a devastating combo of your Psi Warrior abilities.
Control the Battlefield: Use your psionic abilities to control the battlefield. Telekinetic Blast can knock enemies back, giving you an advantage. The Protective Field can protect you and your allies.

Strengths and Weaknesses: Knowing Your Limits

It's important to understand both the strengths and weaknesses of this build so you can play it effectively.

Strengths

High Damage Output: With the combination of Rage, Great Weapon Master, and extra attacks, you can deal a massive amount of damage in melee combat. You are designed to destroy enemies in one hit.
Excellent Survivability: Rage provides resistance to many types of damage, and high Constitution provides a large health pool. This makes you very difficult to kill.
Tactical Flexibility: The Psi Warrior abilities provide a lot of tactical options, allowing you to control the battlefield and deal with a variety of threats. This allows you to deal with multiple problems. With Action Surge, this offers a great advantage.
Good at Range: With the Psi Warrior abilities, you can deal with enemies from a range, which is critical for many fights.

Weaknesses

Reliance on Rage: You will want to use Rage in most combat encounters. This can be problematic if you are fighting multiple fights in a row, or if you forget to use it. This weakness can be mitigated by good resource management.
Limited Spell Slots: This build does not offer any access to spell slots, which can make it hard to deal with specific threats. This can be mitigated by your Psi Warrior abilities, but this does create a major disadvantage. This limits your utility.
Single-Target Focus: While you can deal a lot of damage, your best attacks are usually aimed at one target. Make sure to choose your targets carefully.
