class Mod Request (big offer): Wizarding World aka Harry Potter/Hogwarts Mage mod

[SnaipFanMU]

Hello everyone!

I’m surprised that I haven’t found any information, ideas, or mods on this theme anywhere on the internet, especially on this site. Since the New Year (or Christmas, depending on what’s closer to you) is coming soon, during this magical time of the year, I’d like to propose an idea for a mod for Baldur's Gate 3. This mod would add a new class of wizard, based on the Hogwarts schools of magic, with subclasses corresponding to the four houses: Gryffindor, Slytherin, Ravenclaw, and Hufflepuff. The mod will be closely tied to the lore of the Wizarding World (WW), or simply Harry Potter, while introducing a fresh perspective on BG3's mechanics.

(To make writing the text easier, I’ve run my ideas through ChatGPT, so I apologize in advance for any errors that may occur.)

1. Main ideas for the mod:

Subclass division from level 1: Every wizard will start with a subclass corresponding to one of the houses. At levels 6, 9, and 11, the character will receive significant improvements to their subclass, allowing them to evolve and change their playstyle. New combat/non-combat spells will be learned at each level.

It would also be nice to add a new mana mechanic (so that we don’t have to use the wizard/sorcerer spell charges from the base game). At level 1, the wizard will have 100 mana units, and at level 12, 1000. Mana will regenerate by a set amount each turn, with half the regeneration rate in combat. Casting non-combat spells outside of combat will cost half the mana.

Further discussions about mechanics might also introduce others, such as the Dark Wizard (for repeated use of unforgivable curses) for the dark branch of the hero (similar to the Fallen Knight), or others that fit BG3 and WW.

2. Unique mechanics for each house
Each house will have its own distinct features, both for combat and non-combat spells, as well as unique buffs that reflect the spirit of the house and influence abilities, playstyle, stats, combat, and roleplaying throughout the game.

• Gryffindor: Tank mages with high health, strong defense, and powerful defensive spells. Brave, daring, not the smartest, but beloved by all.
• Slytherin: Dodging mages, focusing on stealth and critical strikes, capable of casting magic at long ranges. Agile manipulators, with a cold mind and ambitions, willing to do anything to achieve their goals.
• Ravenclaw: Intellectual mages, capable of transforming enemies into animals and excelling in the world of knowledge. They strive for wisdom, analyze every situation, willing to do necessary evil, and are not afraid to take risks to achieve their goals.
• Hufflepuff: Druid-like support mages, with strong healing spells and the ability to summon allies. Friendly, hardworking, and kind-hearted, with a strong belief in the value of cooperation and helping others, yet also striving for success and career advancement, unafraid to use their connections to rise to greater heights.

3. General class mechanics
The class will be fully based on magic, and a wand or staff will be required to cast spells. I think we should also add artifacts in the form of wands (basic for each house) and enemies with the same class (and various subclasses) who will also have wands with improved stats. These can be obtained by defeating (or disarming) the enemy (wand loyalty mechanic from the books). Additional equipment elements (robes, hats, etc.) for customization could also be added.

4. Spells
There will be both combat and non-combat spells, adapted for BG3’s mechanics. Spells will be unlocked over levels, starting with simple magic like "Lumos" or "Alohomora" and progressing to powerful unforgivable curses like "Avada Kedavra."

Examples of spells:

• Non-combat:
  Lumos with variations (basic: light around the hero; Lumos Maxima: light orb; Nox: extinguish active light created by the hero);
  Alohomora (opens non-magically locked doors); Legilimency (reads minds during dialogue);
  Imperius (almost the same, but stronger + mind control outside of combat/dialogue, if possible), etc.
• Combat:
  Expelliarmus (disarms enemies);
  Stupefy (stuns enemies);
  Protego (defensive, for example, +AC during the turn or a counterspell outside of their turn).
• Unforgivable: Avada Kedavra (instant death if hit, lower chance if hit big NPCs/not humans/bosses, 0% on constructs/undead, etc.); Crucio (temporary paralysis if hit or huge dmg if lucky, duration depends on chance/skill/house, debuffs on the target and the caster).

A complete list of existing spells can be found online, and we can select the ones that best fit BG3, the hero class, and subclasses.

5. Ideas and features of the houses, general mechanics. Interaction with the world and enemies

Stat modifiers: Each house will affect the wizard's base stats. The character’s personality traits will modify their combat style and overall efficiency in the game.

Spoiler

• Gryffindor – Tank mages: Gryffindors are brave and resilient mages who play the role of tanks with high health and defense. Their magic focuses on boosting protection and supporting allies.

Stats: High health, good defense, average magical damage.

Armor: All types of armor.

Abilities: +2 to AC, Persuasion +3, Athletics +2.

Spells: Unique spell pool, plus some enhanced ones (like combat Bombarda with a Maxim variant).

• Slytherin – Dodging mages: Slytherins are cunning mages who use agility and stealth for critical damage and evasion. Their magic changes the course of battles in their favor.

Stats: High dexterity, high speed, high chance of critical hits.

Armor: Light. Buff to improved dodge from attacks.

Abilities: +3 to speed, Intimidation +3, Acrobatics +2, Stealth +2.

Spells: Unique spell pool + critical hit boost. Easy to cast Unforgivable spells

• Ravenclaw – Intellectual mages: Ravenclaws are intellectuals who use mind magic and manipulate reality. They can turn enemies into animals and calculate every step.

Stats: High intelligence, high magical damage.

Armor: Medium.

Abilities: +5 to Investigation/Perception, Magic +2, Knowledge +3.

Spells: Metamorphosis, Control.

• Hufflepuff – Druid and support mages: Hufflepuffs are kind-hearted mages who focus on healing, summoning allies, and supporting the team. They use their ambitions to achieve goals.

Stats: Medium health, high healing.

Armor: Medium.

Abilities: +3 to speed, +2 to AC, Nature/Medicine +5, Animal Handling +3.

Spells: Healing, Restoration, Animal Summoning.

 

6. An example of spell differences

Lets just speak about Expecto Patronum, which will work against ghosts and undead, and will also summon animal allies (subvariants). Depending on the subclass, the summoned allies will differ (but the animal is chosen):

• Hufflepuff: Heals allies.
• Slytherin: High chance of critical damage.
• Ravenclaw: Increases movement speed and grants +1 additional turn.
• Gryffindor: High health and damage.

7. Moral consequences for using unforgivable curses

Using curses like "Avada Kedavra" or "Crucio" will affect the character's reputation. Using these curses against enemies will lead to moral decline, and using them against allies or NPCs will alter relationships with other characters and possibly affect quest outcomes.

          
Additional features:

• Class modifiers: Each house will have additional stat modifiers, such as increasing dexterity, intelligence, defense, and other important attributes, making each subclass unique in terms of gameplay.
• Special animations: For casting spells, we plan to add new animations that match the magical style of each house.

Why is this mod interesting? This unique combination of magic from the Harry Potter universe with Baldur's Gate 3 mechanics will allow players to immerse themselves in the familiar Hogwarts atmosphere while providing new opportunities for strategic and moral choices. Each subclass has its own unique style, giving players the freedom to choose: be a protector, a tank mage, a stealthy assassin, or a team supporter.

This is all a rough concept of the idea. I hope it interests you! I’d love to hear your opinions and suggestions, and I’m happy to help with further development if anyone is interested in realizing this project.

It will be better if some of modders will say something
