Better Spellcasting

Bind spells to your weapon attacks!

This mod allows you to attach spells from Iron's Spells 'n Spellbooks to individual weapon attacks in a combo chain. 

Features

• Spell-Infused Combos: Attach different spells to each attack in a weapon's combo chain
• Flexible Targeting: Spells can target enemies or yourself (for buffs/heals)
• Customizable Per-Weapon: Define spell combinations in JSON for any weapon
• Mana-Free Casting: Weapon spells don't consume mana by default
• Combo Tracking: The mod accurately tracks your attack combo, even when swinging in the air

How It Works

Define spells in your weapon's Better Combat JSON file:

diamond_sword.json

{
  "attributes": {
    "attack_range": 2.5,
    "category": "sword",
    "attacks": [
      {
        "hitbox": "HORIZONTAL_PLANE",
        "damage_multiplier": 1,
        "angle": 120,
        "upswing": 0.5,
        "animation": "bettercombat:one_handed_slash_horizontal_right",
        "swing_sound": {
          "id": "bettercombat:sword_slash"
        },
        "spell": "irons_spellbooks:firebolt",
        "level": 1,
        "target": "TARGET"
        "trigger": "on_attack"
      },
      {
        "hitbox": "HORIZONTAL_PLANE",
        "damage_multiplier": 1,
        "angle": 120,
        "upswing": 0.5,
        "animation": "bettercombat:one_handed_slash_horizontal_left",
        "swing_sound": {
          "id": "bettercombat:sword_slash"
        },
        "spell": "irons_spellbooks:blood_slash",
        "level": 4,
        "target": "TARGET"
        "trigger": "on_attack"
      },
      {
        "hitbox": "FORWARD_BOX",
        "damage_multiplier": 1,
        "angle": 0,
        "upswing": 0.5,
        "animation": "bettercombat:one_handed_stab",
        "swing_sound": {
          "id": "bettercombat:sword_slash",
          "pitch": 1.2
        },
        "spell": "irons_spellbooks:heal",
        "level": 1,
        "target": "SELF"
        "trigger": "on_hit"
      }
    ]
  }
}

In this example, a diamond sword would cast Firebolt on the first attack, Blood Slash on the second, and Heal (on yourself) on the third!
