from dnd_5e_core.data.loaders import simple_character_generator

# Automatic abilities and traits
fighter = simple_character_generator(5, "dwarf", "fighter", "Gimli")
# Gets: Extra Attack, Darkvision, Dwarven Resilience, etc.

wizard = simple_character_generator(5, "elf", "wizard", "Elrond")
# Gets: Spellcasting, Darkvision, Fey Ancestry, etc.

Combat System

from dnd_5e_core.combat import CombatSystem

combat = CombatSystem(verbose=True)

# Automatic combat decisions:
# - Spellcasters cast spells from back row
# - Fighters use weapons and special attacks
# - Healing spells used on wounded allies
# - Conditions applied automatically

combat.character_turn(character, party, monsters, party)
combat.monster_turn(monster, monsters, party, party, round_num)

Equipment & Magic Items

from dnd_5e_core.equipment import get_magic_item, get_special_weapon

# Magic items
ring = get_magic_item("ring-of-protection")  # +1 AC, +1 saves
wand = get_magic_item("wand-of-magic-missiles")  # 7 charges

# Magical weapons
flame_tongue = get_special_weapon("flame-tongue")  # +1, +2d6 fire
vorpal_sword = get_special_weapon("vorpal-sword")  # Legendary

character.equip(flame_tongue)

Treasure Generation

from dnd_5e_core.mechanics import calculate_treasure_hoard

treasure = calculate_treasure_hoard(
    encounter_level=5,
    difficulty="hard",
    cr=5,
    include_items=True
)

print(f"Gold: {treasure['gold']} gp")
print(f"Items: {[item.name for item in treasure['items']]}")
print(f"Total value: {treasure['total_value']} gp")

🏗️ Architecture

UI-Agnostic Design - Use with any interface:

# Your game provides UI
import pygame  # or tkinter, web framework, etc.

# dnd-5e-core provides game logic
from dnd_5e_core import Character, Monster, CombatSystem

# Game loop
while running:
    # Handle input (your code)
    action = get_user_input()
    
    # Process game logic (dnd-5e-core)
    if action == "attack":
        damage = player.attack(monster)
    
    # Render (your code)
    render_game_state(player, monster)

🔧 Advanced Usage

Multiclassing

from dnd_5e_core.mechanics.subclass_system import MulticlassCharacter

# Fighter 5 / Wizard 3
gish = MulticlassCharacter("Elric")
for _ in range(5): gish.add_class_level('fighter')
for _ in range(3): gish.add_class_level('wizard')

print(f"Spell slots: {gish.get_spell_slots_multiclass()}")

Encounter Building

from dnd_5e_core.mechanics import select_monsters_by_encounter_table

monsters, difficulty = select_monsters_by_encounter_table(
    encounter_level=5,
    available_monsters=all_monsters,
    allow_pairs=True
)

Extended Monsters

from dnd_5e_core.entities import get_extended_monster_loader

loader = get_extended_monster_loader()
goblins = loader.search_monsters(name_contains="goblin", min_cr=1)
