Magic & Spellcasting Mechanics
Overview
Four classes cast spells in Lourdin RPG: Wizard (INT), Cleric (WIS), Paladin (CHA), and Bard (CHA). Each spell costs mana, which fully restores after every combat encounter. Spells are delivered via attack roll, saving throw, or auto-hit depending on the spell. Powerful spells have turn-based cooldowns. Monsters also cast spells — their archetype determines how aggressively.
Lourdin RPG features a comprehensive D&D 5e-inspired spell system for spellcasting classes. Spells use mana, have cooldowns, level requirements, and affect single or multiple targets through five distinct AoE delivery methods. Even monsters use spells — their archetype determines how aggressively they cast.
Master arcane, divine, or bardic magic to become a powerful force on any battlefield.
Which Classes Can Cast Spells in Lourdin RPG?
Four character classes can cast spells, each with unique mechanics and spell focuses:
| Class | Casting Stat | Spell Focus | Mana Pool |
|---|---|---|---|
| Wizard | Intelligence | Damage, AoE, Control | High — scales with INT |
| Cleric | Wisdom | Healing, Support, Radiant | Medium — scales with WIS |
| Paladin | Charisma | Smites, Healing, Auras | Low — scales with CHA |
| Bard | Charisma | Debuffs, Healing, Buffs | Medium — scales with CHA |
What the Spellcasting Stat Affects
- Spell Attack Bonus: Added to d20 rolls on spell attacks
- Spell Save DC: 8 + Stat Modifier + Proficiency Bonus — what enemies must beat
- Mana Pool Size: Higher stat = more mana per level
- Healing/Damage Bonus: Some spells add your stat modifier to the effect
How Does the Mana System Work?
Mana is consumed every time you cast a spell. Each spell has a fixed mana cost shown in the spell selection UI.
Mana Pool Formulas by Class
- Wizard:
10 + ((Level - 1) * 5) + (Level * INT Modifier) - Cleric:
8 + ((Level - 1) * 4) + (Level * WIS Modifier) - Paladin:
6 + ((Level - 1) * 3) + (Level * CHA Modifier) - Bard:
8 + ((Level - 1) * 4) + (Level * CHA Modifier)
Mana Regeneration
- After Combat: Full mana restored when the encounter ends
- Mana Potions: Restore mana during combat — buy from the Merchant
- Leveling Up: Maximum mana increases with level and stat improvements
Mana Management Strategy
- Don't spend all your mana on the first enemies — save big spells for difficult waves
- Keep emergency healing spells in reserve
- When mana runs low, switch to weapon attacks to preserve resources
- Carry Mana Potions for extended or Deadly encounters
- Mana is fully restored after combat — spend it aggressively in long single fights
What Types of Spells Are Available?
1. Damage Spells
- Examples: Magic Missile, Fireball, Lightning Bolt, Sacred Flame, Scorching Ray
- Damage Types: Fire, Cold, Lightning, Thunder, Force, Radiant, Necrotic, Psychic, Acid
- Use Case: Primary offense — choose the right element to exploit monster vulnerabilities
2. Healing Spells
- Examples: Cure Wounds, Healing Word, Mass Healing Word, Lay on Hands
- Healing Bonus: Most healing spells add your casting stat modifier to the total
- Use Case: Emergency survivability in solo play; keeping the party alive in multiplayer
3. Buff Spells
- Examples: Shield (+5 AC for 1 turn), Bless (+1d4 to attacks for 3 turns), Shield of Faith (+2 AC), Bardic Inspiration (+1d6 to next roll)
- Duration: Typically 1–5 turns depending on the spell

4. Debuff Spells
- Examples: Vicious Mockery (-1d4 to enemy attacks), Slow (-2 AC + disadvantage), Blindness, Hold Person
- Effects: Attack penalties, stunned, DoT, AC reduction
- Use Case: Neutralize the most dangerous enemy — a stunned Brute deals zero damage
Spell Delivery Methods
Every spell uses one of four delivery methods that determine whether it hits and how it deals damage:
1. Auto-Hit
Spell always hits — no attack roll required. Guaranteed effect.
No roll needed — effect applies automatically- Examples: Magic Missile (3d4+3 force), Cure Wounds, Healing Word
- Best For: Guaranteed damage when you can't afford to miss
2. Spell Attack Roll
Roll d20 + spellcasting modifier vs. target's AC. Can critically hit on a Natural 20.
1d20 + Casting Stat Modifier + Proficiency Bonus vs. Target AC- Examples: Ray of Frost, Scorching Ray, Guiding Bolt
- Critical Hit: Natural 20 doubles damage dice — same as weapon crits
3. Saving Throw
The target rolls a saving throw against your Spell Save DC. Failure means full effect.
Spell Save DC = 8 + Casting Stat Modifier + Proficiency Bonus- Examples: Fireball (DEX save), Thunderwave (CON save), Hold Person (WIS save), Slow (WIS save)
- Failed Save: Full damage or full effect applied
- Successful Save: Half damage (damage spells) or no effect (control spells)
Saving Throw Types:
- DEX: Most common — dodge AoE effects like Fireball and Thunderwave
- CON: Resist poison, disease, physical force
- WIS: Resist mind control, charm, Hold Person
- STR: Resist physical push, grapple
- INT: Resist illusions and mind tricks
- CHA: Resist banishment and possession
4. Self-Target
Spell affects only the caster — no roll needed, instant effect.
- Examples: Shield, Haste, Stoneskin, Lay on Hands
- Best For: Personal buffs and emergency self-healing
Area of Effect (AoE) Targeting
AoE spells can damage or affect multiple targets simultaneously — the most powerful force multiplier in the game.
AoE Targeting Types
1. Single Target
Affects one enemy. Most spells and all weapon attacks use this.
- Examples: Magic Missile (single), Cure Wounds, Ray of Frost
2. All Enemies
Hits every enemy in combat simultaneously. No target limit.
- Examples: Fireball, Thunderwave, Chain Lightning
- Mechanic: Each enemy rolls a separate saving throw
- Best For: Large groups — use when facing 3+ enemies
3. Multi-Target
Hit up to X chosen targets (typically 2–3). Player selects specific enemies.
- Examples: Scorching Ray (3 targets), Eldritch Blast (multi-beam)
- Best For: Splitting damage between high-priority targets
4. Cleave
Primary target takes full damage; a secondary target takes reduced splash damage.
- Primary: 100% damage
- Secondary: Typically 50% damage
- Best For: Focus damage with bonus splash pressure
5. Chain Lightning
Bounces between targets with diminishing damage per bounce.
- Target 1: 100% | Target 2: 75% | Target 3: 50%
- Examples: Chain Lightning, Arc Lightning
Cooldown System
Powerful spells have cooldowns measured in turns. The cooldown countdown appears in the spell selection UI.
How Cooldowns Work
- Cast a spell with a cooldown (e.g., Fireball — 4-turn cooldown)
- Spell becomes unavailable for X turns — shown in the spell list as "On Cooldown (3)"
- Cooldown decrements by 1 at the end of each of your turns
- When cooldown reaches 0, the spell becomes available again
Example Cooldowns
- Divine Smite (Paladin): 3 turns
- Fireball (Wizard): 4 turns
- Mass Healing Word (Cleric): 5 turns
- Bardic Inspiration (Bard): 2 turns
Cooldown Rotation Strategy
- Save high-cooldown spells for dangerous enemies or boss encounters
- Never waste Fireball on a single weak enemy — wait for a group
- Plan a rotation: use Spell A on turn 1, Spell B on turn 3 while A cools down
- Always have a fallback spell available — weapon attacks when all spells are cooling

Monster Spellcasting & Archetypes
Monsters are not passive opponents — they actively cast spells based on their archetype. Understanding which monsters cast spells and how often they do it changes your entire combat strategy.
| Archetype | Spell Cast Chance | Spell Focus | How to Counter |
|---|---|---|---|
| Caster | ~80% per turn | AoE damage, debuffs, control | Kill Casters immediately — their AoE spells can wipe parties |
| Support | ~60% per turn | Heals and buffs allied monsters | Focus Support monsters first — preventing healing negates all your damage |
| Skirmisher | ~30% per turn | Single-target debuffs, DoTs | Use status effect cleanse spells or Cleric dispels to remove debuffs |
| Brute | ~10% per turn | Occasional burst damage spells | Low spell threat — treat as melee fighter, stack AC |
| Tank | ~5% per turn | Rare self-buffs (AC, resistance) | Almost never casts — use AoE spells to strip resistances |
Monster Spell Behavior
- When a monster decides to cast, it selects from its assigned spell list — each monster has specific spells based on type
- Caster monsters prioritize AoE spells when multiple player characters are in range
- Support monsters always attempt to heal the most wounded allied monster first
- Monster spells use the same mechanics as player spells — saving throws, attack rolls, mana pools
- Higher difficulty encounters spawn monsters with stronger spell variants and higher Spell Save DCs
Spellcasting Strategy
Solo Combat Tips
- Turn 1: Use AoE spells (Fireball, Thunderwave) to deal damage to all enemies immediately
- Mid Battle: Switch to single-target focus on Support and Caster archetypes
- Low HP: Prioritize self-healing — dead casters deal zero damage
- Low Mana: Use basic weapon attacks to conserve mana for emergencies
Party Combat Synergies
- Bard + Wizard: Vicious Mockery debuff → Fireball combo = massive damage
- Cleric + Party: Mass Healing Word on low-HP turns, Bless for sustained damage increase
- Paladin: Save Divine Smite for when you roll a Natural 20 — doubled smite dice on crits
- Communication: Call out cooldowns and mana levels so the party can time AoE bursts
Common Mistakes
- Using AoE spells on a single enemy — waste of mana and cooldown
- Burning all mana in wave 1 — save cooldown spells for tougher enemies
- Ignoring Support monsters — they undo your entire last turn
- No backup plan — weapon attacks are always available when mana is empty
- Forgetting status effects — Slow or Blind on a Brute negates massive incoming damage
