Holyday Studios launched Firestone into Early Access on 26 September 2019 and shipped the 1.0 version on 1 April 2024. You field a party of up to five heroes plus one guardian against waves of enemies in the setting of Alandria, and the party keeps fighting while you are offline. Progress comes from research trees, slot-based gear enchanting and repeated ascensions rather than from manual combat input.
Picking the right build determines how your experience plays out. These builds are ranked by overall effectiveness, factoring in damage, survivability, gear requirements, and how well they scale into endgame. New to the game? Start with our beginner's guide first.

A-Tier: Warrior
Warrior is a top-performing option in Firestone: Online Idle RPG.
Core Setup
| Slot | Choice | Why |
|---|---|---|
| Primary Equipment | Weapon | The attack slot, and it only boosts the single hero wearing it. |
| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | Five hero party plus one guardian | You bring five heroes and a single guardian into each fight. |
How to Play Warrior
Warrior focuses on a balanced approach to content.
Why this build works: Weapon does the damage and Five hero party plus one guardian keeps it running, which is why this sits at the top of the list. See our weapons guide for detailed equipment breakdowns.
Pros:
- Highest overall performance
- Straightforward gearing path
- Works in all content types
Cons:
- Popular pick, resources may be contested
- Needs specific gear to reach full potential
A-Tier: Mage
Mage is a strong option in Firestone: Online Idle RPG.
Core Setup
| Slot | Choice | Why |
|---|---|---|
| Primary Equipment | Chestplate | The health slot for one hero. |
| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | Slot-based gear enchanting | Enchantment levels attach to the equipment slot rather than to the item sitting in it, so upgrading a Common chestplate to a Mythic one keeps the enchantment level you already paid for. |
How to Play Mage
Mage focuses on a balanced approach to content.
Why this build works: Pair Chestplate with Slot-based gear enchanting and the build stops depending on a good start, so it holds up across most content. See our weapons guide for detailed equipment breakdowns.
Pros:
- Most versatile option
- Straightforward gearing path
- Works in all content types
Cons:
- Lower peak damage than S-tier
- Needs specific gear to reach full potential
A-Tier: Priest
Priest is a strong option in Firestone: Online Idle RPG.
Core Setup
| Slot | Choice | Why |
|---|---|---|
| Primary Equipment | Boots | The armour slot for one hero. |
| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | Firestone and Meteorite research trees | Gold, firestones and meteorites each buy different upgrade trees, and meteorites in particular gate the tier 2 and tier 3 equipment unlocks. |
How to Play Priest
Priest focuses on a balanced approach to content.
Why this build works: Firestone and Meteorite research trees covers the gap Boots leaves open, so the build stays usable even when a fight goes badly. See our weapons guide for detailed equipment breakdowns.
Pros:
- Best survivability
- Straightforward gearing path
- Works in all content types
Cons:
- Slower clear speeds
- Needs specific gear to reach full potential
A-Tier: Druid
Druid is a specialized option in Firestone: Online Idle RPG.
Core Setup
| Slot | Choice | Why |
|---|---|---|
| Primary Equipment | Wrist | One of the account-wide slots: it raises attack across all heroes rather than just the wearer. |
| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | War Machine campaign | War machines run a separate campaign from your hero party, fighting enemy war machines and other players' machines with their own upgrade path. |
How to Play Druid
Druid focuses on a balanced approach to content.
Why this build works: This one leans on War Machine campaign rather than raw numbers, and Wrist is what makes that trade pay off. See our weapons guide for detailed equipment breakdowns.
Pros:
- Strong in group/team content
- Straightforward gearing path
- Excels in its niche
Cons:
- Weaker solo performance
- Requires deep game knowledge
A-Tier: Paladin
Paladin is a specialized option in Firestone: Online Idle RPG.
Core Setup
| Slot | Choice | Why |
|---|---|---|
| Primary Equipment | Relic | The slot that boosts every attribute on every hero, which makes it the highest-value slot on the account. |
| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | Ascension resets | Ascending wipes campaign stage progress in exchange for permanent multipliers, which is the actual engine of long-term growth. |
How to Play Paladin
Paladin focuses on a balanced approach to content.
Why this build works: Relic and Ascension resets pull in the same direction here, which separates this from the safer picks above. See our weapons guide for detailed equipment breakdowns.
Pros:
- Unique, rewarding playstyle
- Straightforward gearing path
- Excels in its niche
Cons:
- High skill floor, punishing when misplayed
- Requires deep game knowledge
Build Progression Path
- Start with Mage: the most forgiving option for learning the game
- Transition to Warrior once you understand core mechanics and have access to Weapon
- Keep a Priest setup for content that keeps killing you
- Try Paladin for a fresh experience once you've mastered the basics
Follow our walkthrough for the optimal progression path through each area.
Gearing Tips
- Invest in your primary equipment first, since it gives the biggest power spike. See our weapons guide for rankings.
- Enchant the slot and not the item. Levels stay attached to the slot, so a Common chestplate enchanted twice stays at level 2 when you replace it with a Mythic one, which means you should never wait for good gear before enchanting.
- Watch the enchant cost curve before committing gold. Costs double per level up to level 8, rise 50 percent per level after that, then double again for levels 13 and 14, so pushing one slot far past the others burns gold you could spend across four other slots.
- Don't spread upgrade resources across multiple builds until endgame
