| 1–30 | 60 Rough Blasting Powder | 60 Rough Stone; keep it. | You may overshoot 30—stop once you have enough powder. |
| 30–50 | 30 Handful of Copper Bolts | 30 Copper Bars; keep them. | None; they are components for the next step. |
| 50–51 | Arclight Spanner | 6 Copper Bars; keep permanently. | Required tool. |
| 51–75 | ≈30 Rough Copper Bomb | Copper Bars + Handful of Copper Bolts + Rough Blasting Powder + Linen Cloth. | Any orange Copper device if Linen prices spike. |
| 75–90 | 60 Coarse Blasting Powder | 60 Coarse Stone; keep it. | Continue Rough Copper Bomb briefly if still orange and cheaper. |
| 90–100 | 20 Coarse Dynamite | Coarse Blasting Powder + Linen Cloth. | Use other orange Coarse recipes if Linen is expensive. |
| 100–105 | 5 Silver Contact | 5 Silver Bars. | Flying Tiger Goggles if Silver Bars are expensive. |
| 105–125 | 25 Bronze Tube | 50 Bronze Bars + Weak Flux; keep useful tubes. | Other orange Bronze components are okay if bars fluctuate. |
| 125–135 | 10 Standard Scope | Bronze Tube + Moss Agate. | Start Heavy Blasting Powder if Moss Agate is expensive. |
| 135–150 | Heavy Blasting Powder + Whirring Bronze Gizmo | Heavy Blasting Powder + Whirring Bronze Gizmo; make enough of both for the next steps. | Mix the two recipes to avoid overproducing one component. |
| 150–160 | ≈15 Bronze Framework | Bronze Bars + Medium Leather + Wool Cloth; save the frameworks. | Stop early if you reach 160 before 15. |
| 160–175 | 15 Explosive Sheep | Heavy Blasting Powder + Whirring Bronze Gizmo + Bronze Framework + Wool Cloth. | Keep 5 if you intend Goblin Engineering. |
| 175–194 | ≈60 Solid Blasting Powder | 120 Solid Stone; save it. | Iron Grenade if you need a few points and have spare Iron. |
| 194–195 | Gyromatic Micro-Adjustor | 4 Steel Bars; keep permanently. | Required tool. |
| 195–200 | ≈7 Mithril Tube | 21 Mithril Bars; stop at 200. | Iron Grenade if Mithril is unusually expensive. |
| 200–215 | 20 Unstable Trigger | Mithril Bars + Mageweave Cloth + Solid Blasting Powder; keep the triggers. | None—needed for Hi-Explosive Bombs. |
| 215–238 | 40 Mithril Casing | 120 Mithril Bars; keep them. | Make only until the target if bars are expensive. |
| 238–250 | 20 Hi-Explosive Bomb | Mithril Casing + Unstable Trigger + Solid Blasting Powder. | Use other orange explosives if you over/under-produced components. |
| 250–260 | ≈30 Dense Blasting Powder | 60 Dense Stone. | Expect a few extra yellow crafts. |
| 260–285 | ≈35 Thorium Widget | 105 Thorium Bars + Runecloth. | Check vendor availability of the schematic before bulk-buying. |
| 175–190 | Solid Blasting Powder | Use Solid Stone as long as it is cheap. Get to at least 190 this way; if stone is dirt-cheap, you can keep pushing powder toward 195. | Do not overpay for Solid Stone just to avoid Mithril. The goal is cheaper leveling, not a rigid recipe list. |
| 190–210 | Big Iron Bomb | Start Big Iron Bombs at 190. Each craft uses Iron Bars, Heavy Blasting Powder and a Silver Contact and makes 2 bombs. | Goblin Engineers need this for their specialization quest, so either save them for your own specialization or throw them on the Auction House as they should sell pretty easily. |
| Before 225 | Gyromatic Micro-Adjustor | Make one if you do not already have it. You will need it as a tool for both goggles recipes. | This is a permanent Engineering tool, not a leveling material sink. |
| 210–225/230 | Hi-Impact Mithril Slugs | Use whatever Mithril you already own here: 1 Mithril Bar + 1 Solid Blasting Powder makes 200 slugs. Move to goggles at 225, or stay on slugs a little longer if Star Rubies / leather are expensive. | This is where the route still spends some Mithril, but far less than mass-producing Mithril Casings. Skill-ups become less reliable as you approach 230. |
| 225–245 | Spellpower Goggles Xtreme | 4 Thick Leather + 2 Star Rubies each. The recipe remains orange through 244, making this a predictable 20-point bridge from 225 to 245. | Coffee break: these have a 45-second craft time each. Twenty crafts is about 15 minutes of watching the progress bar. |
| 245–250 | Rose Colored Goggles | 6 Thick Leather + 2 Star Rubies each. Use these for the final five points to 250. | These also take 45 seconds per craft, so the 245–250 stretch alone is about 3 minutes 45 seconds of crafting. |
| 250–260 | Dense Blasting Powder | Turn Dense Stone into Dense Blasting Powder. Save the powder for the next step. | This recipe goes yellow/green quickly, but Dense Stone should be very cheap. |
| 260–270 | Dense Dynamite | 2 Dense Blasting Powder + 3 Runecloth makes 2 Dense Dynamite. Use this to finish the low-Mithril detour. | This is the tedious end of the route: Dense Dynamite is green from 260 onward, so expect to make extra. Check Runecloth prices before committing. |
| 270–285 | Thorium Widget | Rejoin the normal route here with Thorium Bars + Runecloth. | The Mithril-saving detour is over at 270; continue with the standard guide from here. |
| 285–300 | ≈20 Thorium Tube | 120 Thorium Bars. | Alternate Recipe: Thorium Shells can be cheaper if you have extra Dense Powder left over |
