Forge Calculator + Inventory Optimizer (Roblox The Forge)
Open the full forge calculator with real weapon/armor odds, active traits, damage & health previews, and the inventory optimizer that searches all your ores for the best crafts. Client-side and fast.
Live Calculator + Optimizer
Use the full calculator and optimizer without leaving this page. All calculations and inventory storage run locally in your browser.
Want the best possible crafts from everything you own?
Composition & Traits
Add ores on the right to see composition and trait rolls.
Value pillars
Transparent odds
Weapon and Armor probabilities surface instantly with visible trait thresholds and stat previews.
Inventory-first
Optimizer ranks what you can craft today, flags missing ores, and keeps your counts locally.
End-to-end planning
Upgrade pathing and mining ROI show how to reach the next pickaxe and which ores to farm first.
Data you can verify
Pickaxe, ore, and forge tables mirror in-game data; versioned changes stay readable for SEO and trust.
Instant forge calculator
Mix up to four ores, toggle Weapon or Armor, and see success rate, traits, and damage/health preview without refreshing.
Live sample
| Result | Success | Traits | Preview |
|---|---|---|---|
| Greatsword | 62% | Shatter, Ember | Damage 145-172 |
| Great Axe | 21% | Ember | Damage 118-151 |
| Colossal Sword | 9% | Shatter | Damage 173-190 |
- Traits fire at 10% ore share and stack when multiple ores cross the threshold.
- Composition math shows ore percentages and the multiplier contribution per ore.
- Mode switch adjusts weapon vs. armor tables and the stat preview that matters.
Inventory optimizer
Paste ore counts, pick Tank or Damage, and get ranked crafts you can build right now. Unavailable crafts stay visible with clear requirements.
Reachable-first output
- Heavy Chestplate - 74% success, Tank focus, Traits: Fortify + Ember. Ready to craft.
- Straight Sword - 89% success, Balanced, Traits: Keen + Ember. Uses common ores.
- Greatsword - 52% success, Damage, Traits: Shatter. Needs +2 Gold to unlock.
Local storage preserves your counts so you can refresh mid-session without losing progress.
Why use the optimizer
Smart inventory analysis
Reads your ore counts and filters out crafts you cannot make yet.
Adaptive trait targeting
Balances survivability and damage traits depending on your goal.
Probability breakdown
Shows success odds, required ores, average multipliers, and trait bonuses.
Saved locally
Keeps your inventory in local storage so you can return without retyping counts.
Stat previews
Damage or health estimates for every recommended craft, before you commit.
Craft-ready recipes
Exact ore composition for each suggestion so you can copy it straight into the forge.
How to use
- Enter counts for each ore you own (search by name to find them quickly).
- Pick your focus: Tank for defense-heavy armor or Damage for offensive weapons.
- Review the ranked craft list with success probability, ore requirements, and expected stats.
- Copy the recommended composition and craft it in-game.
- Return after crafting and update your inventory to get fresh recommendations.

Tank vs. damage priorities
Tank builds
Favor ores that boost health and defensive traits. Great for Heavy Helmets, Leggings, and Chestplates.
Damage builds
Prioritize multipliers and offensive traits for weapons like Greatswords, Katanas, or Gauntlets.
The optimizer shows when a recipe is unavailable (for example, needing more total ores). It guides you toward reachable crafts first.
Example recommendations
- Early stockpile: Plenty of Copper and Iron? Get a reliable Straight Sword before chasing rare ores.
- Mid-game mix: Add Silver and Gold to push multipliers while keeping odds healthy.
- Late-game spike: Feeding Fireite, Magmaite, or Arcane Crystal raises ceilings—the optimizer will flag the best pairing.
Every suggestion includes ore counts, activated traits, estimated damage or health, and the effective multiplier.
Optimizer FAQ
- Do I need an account? No accounts or sign-ups. Inventory saves locally in your browser.
- Can I switch priorities? Yes. Toggle tank or damage at any time to recalc the best crafts for that focus.
- What if I am missing ores? The optimizer marks crafts as unavailable when you need more total ores. Use the counts to plan your next mining run.
- Is it free? Yes. The Forge Inventory Optimizer is free to use for all players.
- Will it work on mobile? Clean labels, ranked lists, and short descriptions stay readable on phones while you craft.
Upgrade path planner
Plot the route from your current pickaxe to a target, with time-to-farm estimates and the crafts unlocked at each stage.
Mining ROI dashboard
Compare ore value per minute and required power to know what to mine next.
| Ore | Value/min | Req. Power | Notes |
|---|---|---|---|
| Copper | 220 | 2 | Great starter stockpile for steady odds. |
| Silver | 460 | 4 | Balances probability with early traits. |
| Gold | 710 | 6 | Pushes multipliers without tanking success. |
| Ruby | 980 | 9 | High ceiling ores for explosive builds. |
Traits and thresholds
- Traits activate at 10% ore share and stack across ores that cross the line.
- Weapon traits emphasize damage multipliers like Shatter and Ember.
- Armor traits emphasize health and mitigation like Fortify and Regenerate.
- Composition view explains which ore triggered which trait for transparency.
Damage and health preview
Keep stat previews visible next to probability tables to weigh reliability vs. ceiling.
Weapons
- Damage ranges update instantly as you edit the mix.
- Trait tooltips show trigger thresholds and effects.
- Mode toggles for Balanced or Damage-forward reorder the list.
Armor
- Health preview responds to every ore change.
- Tank focus highlights defensive traits first.
- Unavailable crafts show what to add for a viable roll.
Strategy modes
- Conservative: Emphasize high-probability ores and steady traits for reliable crafts.
- Balanced: Keep two traits active while holding success above 60%.
- Explosive: Push rare ores past 10% thresholds for aggressive multipliers.
Switching modes updates how the calculator orders results and how the optimizer ranks crafts.
Example mixes
Starter steadiness
Stone + Copper + Iron -> Straight Sword at ~82% with Keen trait. Safe farming baseline.
Mid-game balance
Silver + Gold + Mushroomite -> Balanced mode to keep two traits alive while nudging multipliers upward.
Explosive push
Sapphire + Ruby + Darkryte -> Explosive mode for higher ceilings; expect 40-60% success with hard-hitting traits.
Armor-first tanking
Obsidian + Uranium + Emerald -> Heavy armor with Fortify and Regenerate traits, tuned for Tank focus.
Quick start steps
- Select Weapon or Armor, then pick Balanced, Tank, or Damage focus.
- Add up to four ores via search; adjust counts; remove with one tap.
- Watch success rate, traits, and stat preview update live.
- Copy a mix or send it to the optimizer to see if your inventory supports it.
