Description

This mod adapts LaserLlama's Alternate Fighter homebrew class to Baldur's Gate 3. This homebrew takes the idea of the Battle Master subclass' maneuvers and uses it as the template for the base Fighter class, in the form of Exploits. It contains the base Fighter class and four subclasses: the Champion, the Arcane Knight, the Marksman, and the Master at Arms. It includes 13 new or altered Fighting Styles and 40+ Exploits. The best way to get an idea of how the class works is probably to read LaserLlama's original homebrew. Many features/abilities are changed in subtle and sometimes not-so-subtle ways in order to accomodate the limitations of the game engine (see the lists below).

INSTALLATION

Make sure you have all the requirements: BG3SE, ImprovedUI + the ImprovedUI Assets optional file, and BuLib. Make sure that BuLib is higher in your load order (i.e. loads before) than this mod.

I strongly recommend using BG3ModManager

If you are already a Fighter, you need to respec with Withers to see the changes from this mod.

COMPATIBILITY

Incompatible with any other mod that changes the base Fighter class. Mods that change Fighter subclasses probably won't crash the game, but they won't do anything.

This mod uses the Battle Master's Superiority Dice for the Exploit Dice. It might be incompatible with other mods that modify this resource, though the most likely result of this is merely a wrong description (unless the other mod changes things like when Superiority Dice recharge, then the last mod in the load order will "win").

Some compatibility with level 13+ mods. You MUST multiclass beyond level 12.

The Arcane Knight will have its spell lists updated with spells from the 5e Spells mod, if it is present. 5e Spells should be ABOVE BU_LaserllamaFighter in your load order.

I will not add compatibility for other spell mods, however I have provided a ScriptExtender function to allow others to make compatibility patches if they wish. To use it, a mod can put the following call(s) in its BootstrapClient.lua file: Mods.BU_LL_Fighter.RegisterArcaneKnightSpell(<modName>,<spellId>,<spellLevel>), where <modName> is a readable name identifying your mod (for logging clarity in case of conflicts), <spellId> is the name of the spell in the stats (e.g. "Projectile_MagicMissile"), and <spellLevel> is either 0 (cantrip), 1 or 2. Your submod should be below this mod load order (and also below the spell mod in question, if you are making a compatibility patch for a different spell mod). If you don't understand what any of this means, there are other places where you can learn to make script extender mods.

Fighting Styles

• Archery: gain +2 bonus damage with ranged weapons (unchanged from vanilla)
• Classical Swordplay: gain +1 bonus to attack rolls and AC while wielding a Finesse weapon and not wearing heavy armor or a shield
• Defensive Fighting: gain +1 AC when wearing armor or a shield
• Dueling: while wielding a melee weapon in one hand and no other weapons, gain +2 to damage rolls (NOTE: this will not work when you are wielding a versatile weapon without wielding a shield)
• Dual Wielding: whey you use the attack action while two-weapon fighting, you can make the off-hand attack without using a bonus action, and you add your ability modifier to the damage of this attack. (NOTE: The "Toggle Dual Wielding" toggle must be OFF for this fighting style to work properly. If it is on, the game will automatically eat your bonus action before I can do anything about it.)
• Featherweight Fighting: while wielding only light weapons, gain +3m/10ft. movement speed, and gain +1 bonus to your damage rolls if also not using medium or heavy armor or a shield
• Great Weapon Fighting: when wielding a heavy two-handed (NOTE: not versatile) weapon, a total roll of 5 or lower on the damage dice is treated as a 6 (NOTE: this does *not* suffer from the vanilla bug with minimum damage and will *only* increase base weapon damage, not the rolls of any additional magical/coating damage)
• Improvised Fighting: once per turn, roll damage twice and take highest when making an improvise weapon attack (attack with object or throw an object or a weapon that does not have have the thrown property)
• Melee Marksman: no disadvantage when ranged attacking in melee (NOTE: this suffers from the same bug as the vanilla Crossbow Expert feat: you only lose disadvantage if the only creature threatening you is your target. This is a hardcoded limitation right now), and you make a ranged attack in melee range, you can use a bonus action to make an unarmed melee attack against it, dealing 1d4+Strength mod on hit.
• Protector: when a creature attacks you or an ally within 1.5m/5ft., you can use a reaction to add your proficiency bonus to the target's AC. You must be wielding a shield or a melee weapon.
• Strongbow: you can use your Strength modifier on attacks with shortbows and longbows, and if you do, you gain +1 bonus to damage.
• Thrown Weapon Fighting: +2 damage to throw attacks with weapons that have the thrown property
• Versatile Fighting: +1 bonus to attack rolls while wielding a versatile weapon and no shield.
  

Exploits
NOTE 1: unless otherwise noted, all of these require the use of one Exploit Die
NOTE 2: a big change from LaserLlama's homebrew, is that all abilities that allow you to add a roll to an ability or skill check work like Guidance in BG3: you cannot do it as a reaction to a skill check, but instead gain the roll bonus for the next 10 turns. This does work in conversations, obviously. This is due to engine limitations
NOTE 3: IMPORTANT: Some of these Exploits have ability score prerequisites. These are listed in-game when selecting the Exploit, but this cannot be enforced on the level-up screen. YOU WILL NOT BE ABLE TO USE THESE ABILITIES UNTIL YOU MEET THE ABILITY SCORE REQUIREMENTS. Normal abilities will show as disabled, but Interrupts/Reactions will simply not show up until you meet the ability score requirements, again due to engine limitations.
NOTE 4: These are obviously crudely summarized descriptions, to save space. The descriptions are more clear in-game.

• Aggressive Sprint: rush in a straight line up to your movement speed towards an enemy. From level 5, make an attack at the end of this movement.

• Dirty Hit: on hit, target makes CON save or takes additional damage equal to your Exploit Die and falls prone until the start of your next turn.
• Execute: in place of an attack, target prone or incapacitated enemy and expend Exploit Dice up to your proficiency bonus. Roll 2 Exploit Dice for each die you expended, add your Strength modifier, and if the total is equal to or greater than the target's current Hit Points, it dies. Otherwise, it takes damage equal to one roll of your Exploit Die.
• Heroic Will: add Exploit Die to an Intelligence, Wisdom, or Charisma saving throw.

This uses your concentration (as if concentrating on a spell), and the effect ends if you lose concentration.
• Mythic Resilience: when taking damage, expend Exploit Dice up to your proficiency bonus to reduce the damage by three rolls of your Exploit Die for each die expended + your Constitution modifier, then gain 10 Temporary Hit Points per die expended (NOTE: unfortunately, you don't see how much damage you would take on the interrupt screen. I'm looking for ways around this but it is currently an engine limitation.)
• Thunderous Shot: expend Exploit Dice up to your proficiency bonus and make a ranged attack that deals piercing damage equal to two rolls of your Exploit Die per die expended + your Dexterity modifier to each target in a line (DEX save for half damage).
• War Cry: enemies within a 10m/30ft. cone must make a WIS save or drop their weapons and be frightened of you for 10 rounds. They can make a WIS save to end the effect early if they end their turn without line of sight to you.
