Loomian Legacy Damage Calculator – Complete Battle Mechanics Guide
Welcome to the most comprehensive Loomian Legacy damage calculator and strategy guide on the web. Whether you are a competitive PvP player, a team builder, or just starting your journey through Roria, understanding how damage is calculated is the key to victory. This tool simulates the exact damage formula used in Loomian Legacy (by Llama Train Studios on Roblox) and gives you real-time feedback on every move, stat, and modifier.
1. The Damage Formula – Explained
The core formula for attack damage in Loomian Legacy is:
Damage = ((2 × Level / 5 + 2) × Power × Attack × Modifiers) / (50 × Defense)
- Level – the attacking Loomian's level (1–200). Higher level scales damage linearly.
- Power – the base power of the move (e.g., Thunder = 120, Leaf Storm = 130).
- Attack – the relevant attacking stat (Melee or Ranged) after all boosts from UPs, TPs, and nature.
- Defense – the target's relevant defensive stat (Melee Defense or Ranged Defense).
- Modifiers – a product of up to six multipliers: targets (0.75 for multi-target), critical (1.5), type effectiveness, STAB, burn/frostbite (0.5), and random (0.85–1.0).
This formula is identical to the one used in the game client. Our calculator applies every modifier in the correct order, so you can trust the numbers for your battle planning.
2. Type Effectiveness – The Core of Strategy
There are 17 types in Loomian Legacy: Fire, Water, Plant, Light, Dark, Ice, Electric, Air, Bug, Earth, Toxic, Metal, Ancient, Spirit, Brawler, Mind, and Simple. Each type has strengths and weaknesses against other types. The chart above shows the exact multipliers:
- 2× (super effective) – the move deals double damage.
- 0.5× (not very effective) – the move deals half damage.
- 0× (immune) – the move deals no damage.
- 1× (neutral) – standard damage.
When a defender has two types, the effectiveness multipliers multiply together. For example, a Fire/Plant type hit by a Water move: Water is 2× against Fire and 0.5× against Plant → 2 × 0.5 = 1× (neutral). This stacking is what makes dual-type Loomians so interesting.
3. STAB – Same Type Attack Bonus
If the move's type matches one of the attacker's types, the move gains a 1.2× power boost (sometimes listed as 1.25× in older sources, but the current in-game value is 1.2×). For example, a Fire-type Loomian using a Fire move gets STAB. Our calculator uses 1.2× as the standard, with an option for 1.5× if you're using certain abilities or items.
4. Critical Hits
Critical hits multiply the final damage by 1.5×. The base critical hit rate is 1/24 (about 4.17%). Abilities like Marksman or Luck of the Sea can increase the critical multiplier to 2.25×. Critical hits also ignore the defender's positive stat stage changes (but not negative ones). Our calculator includes a checkbox to simulate a critical hit.
5. Stat Stages – Boosts and Drops
Stat stages range from -6 to +6. The multipliers are:
- +6: 4.0× | +5: 3.5× | +4: 3.0× | +3: 2.5× | +2: 2.0× | +1: 1.5×
- 0: 1.0× | -1: 0.67× | -2: 0.5× | -3: 0.4× | -4: 0.33× | -5: 0.29× | -6: 0.25×
These multipliers apply to the attacker's Attack stat and the defender's Defense stat independently. Our calculator lets you set both stages for precise simulation.
6. Random Roll – The 0.85–1.0 Variance
Every move in Loomian Legacy has a random damage multiplier between 0.85 and 1.0. This introduces a small but meaningful variance. Our calculator shows both the minimum (0.85 roll) and maximum (1.0 roll) damage, so you know the best and worst possible outcomes.

Unique Points (UPs) – each stat can have up to 200 UPs, but the total across all stats is capped at 200 per Loomian. UPs add directly to the final stat. For example, 200 UPs in Attack at level 50 can add roughly 40–50 points.
Training Points (TPs) – each stat can receive up to 500 TPs, with a total cap of 500 TPs across all stats. TPs are earned through battles and are the primary way to customize your Loomian's stat spread.
Natures – a nature boosts one stat by 10% and lowers another by 10%. Neutral natures (like Hardy) have no effect. Always consider your nature when calculating your final Attack or Defense stat.
8. Abilities, Items, and Weather
Many abilities and items modify damage. For example:
- Power Cuffs – boost move power by 20%.
- Rageful Plushie – boosts Attack by 10% when the Loomian is below 50% HP.
- Drop of Youth – boosts Defense by 10% when the Loomian is above 50% HP.
- Weather – Sunny weather boosts Fire-type moves, Rainy boosts Water-type moves, etc.
While our calculator focuses on the core formula, you can manually adjust the Attack, Defense, and Power fields to account for these effects.
9. Multi-Target Moves
In double battles, moves that hit both opposing Loomians have a 0.75× damage modifier. This is to balance the advantage of hitting two targets at once. Our calculator includes a checkbox for this.
10. Burn and Frostbite
Burn (from Fire-type moves) and Frostbite (from Ice-type moves) reduce the target's Attack by 50% (a 0.5× multiplier on the Attack stat). This is a powerful debuff that can swing battles. Our calculator includes a checkbox to apply this effect.
11. How to Use This Calculator Effectively
- Enter your attacker's level, Attack stat, and move power. Use the final in-game numbers (including UPs, TPs, and nature).
- Select the move type and the defender's types. The calculator will automatically compute type effectiveness.
- Set stat stages, STAB, critical, and other modifiers. Be precise – even a small change can alter the outcome.
- Click "Calculate Damage". You'll see min, max, and percentage of the defender's HP.
- Experiment! Try different move combinations, natures, and stat spreads to find the optimal strategy.
12. Competitive PvP Applications
In competitive PvP, damage calculation is everything. You need to know:
- OHKO thresholds – can your move one-shot the opponent?
- 2HKO / 3HKO – how many hits to KO?
- Bulk benchmarks – how much Defense do you need to survive a specific move?
- Speed tiers – while not directly damage, speed determines who moves first, which is critical.
Use this calculator to test every scenario before you battle. It's the same math the game uses, so you can trust the results.
13. Common Moves and Their Base Powers
- Thunder (Electric, Ranged) – 120
- Leaf Storm (Plant, Ranged) – 130
- Earthquake (Earth, Melee) – 100
- Sky Slash (Air, Melee) – 85
- Phantom Slash (Spirit, Melee) – 90
- Iron Bash (Metal, Melee) – 80
- Fire Punch (Fire, Melee) – 75
- Dark Pulse (Dark, Ranged) – 85
- Ice Beam (Ice, Ranged) – 95
- Tri-Beam (Typeless, Ranged) – 80
14. Advanced Strategies – Stage Manipulation
Moves that raise your Attack or lower the opponent's Defense are invaluable. For example, a single stage boost (+1) gives a 1.5× multiplier, while a drop (-1) gives a 0.67× multiplier on the opponent's Defense. Stacking these can turn a 2HKO into a OHKO. Our calculator lets you simulate these scenarios instantly.
15. The Importance of the Random Roll
Because of the 0.85–1.0 random roll, you should always plan for the worst-case scenario (0.85). If your minimum damage still KOs the opponent, you have a guaranteed win. If only your maximum damage KOs, you're relying on luck. This is why our calculator shows both values.
16. Frequently Asked Questions
Q: Does this calculator include abilities like Marksman?
A: Not directly, but you can simulate the critical multiplier by using the critical hit checkbox and adjusting the damage manually if needed.
Q: Are UPs and TPs included in the Attack/Defense stats?
A: Yes – you should enter the final in-game stat that already includes UPs, TPs, and nature. The calculator applies stage modifiers on top of that.
Q: What about dual-type defenders?
A: The calculator multiplies the effectiveness of both types. If one type is immune (0×), the result is 0× (no damage).
Q: Is the STAB multiplier 1.2× or 1.5×?
A: In the current version of Loomian Legacy, STAB is 1.2×. However, some abilities or items can change this. We provide both options.
