I can confirm that you can legitimately unlock this if you join a host's server who has the Age to Innovative Age of Fire upgrade! I have tested it and it works by having the person with the upgrade host and the person needing the achievement join via multiplayer. I had a friend join me just to see on the off chance that it would work and it did. Otherwise, the grind for this achievement was a bit long especially since you need to have pretty good gear, be at least level 22+to survive/deal enough damage etc. I also want to preface that
if you die, you will lose a good chunk of money (I believe its 200k-300k) so definitely be cautious especially when entering the Hell biome.
Innovative Age of Fire Requirement List*** Spoiler - click to reveal ***Here is what you need as well in terms of items & money:
- 10x Hell Pepper
- 20x Hellfire Wood
- 20x Heated Mineral
- 200x Diamonds
- 50x Black Gunpowder
- 10,000,000 gold
You can actually find the first 4 items in the Hell biome, but keep in mind that when you enter the biome it will warn you that you have to have a heat resistant level of 1000. You can ignore that as long as you are quick and efficient. Make sure you bring plenty of high-healing foods, platinum pickaxe, and platinum axe to be able to mine/chop these materials. Put campfires down to use your glider to move more efficiently and avoid lava/mobs. The Hell peppers are big skull-like structures, the hellfire wood you can get from these spiny wood-like thorns from the ground, and the heated mineral deposits basically look like red crystals that are jutting out of the ground. Be careful with these, because while you mine them or after, the ground erupts into lava so you'll want to move out of the way or you'll be set on fire for a short period of time.
If you don't want to mine diamonds in the Hell biome, you can find some on several maps and caves.
Black gunpowder can be made from Saltpeter (2x feces and using an aging facility), Charcoal (burn log in a campfire or furnace), and sulfer (mined in abandoned mines or fished from desert island springs).
10mil Gold*** Spoiler - click to reveal ***Aside from selling weapons and stuff you don't need from fights and looting, what I ended up doing was first: Make as many Statue of Liberties as possible (you can craft them at the very bottom of the work bench) which nets you $326,748. This isn't too sustainable if you don't want to search for the pillar towers on harder maps or the other resources it requires. After doing that, what I ended up doing was creating a salmon farm by making 6 Livestock farms on the first island we spawn on. I placed them in a 2x3 like below, giving you room in the middle to go in a circular motion to collect the resources (You want the tank shaped things facing the outside so its easier for you run through the middle).

After you've built this, you will need to make Monster prisms (takes iron ingots) and then equipped them. There are 2 bears that spawn on the island and if this is your last achievement, you should be able to hit the bears with a few punches (fists, no weapons) to knock its health down to red. When its super low, you'll want to hit to throw the monster prism. Make sure your reticle and body are facing the bear or else you'll throw it randomly. If you are successful, the prism will drop down after hitting the bear and you can collect it. It will take practice, but it's really easy to pick up. If you end up missing your throws, which I have many times, you have a few seconds to get to the ball and try and pick it up or else it will despawn.
After collecting all the materials and capturing as many bears as you can, you are going to want to face the Livestock farm and throw the bear prism at the inside gray part of it (you can also aim on the top, but its way easier to hit the sides as long as your reticle and body are facing it). If done successfully, the bears will be stuck in the machine and will start making Salmon.
THIS PART IS IMPORTANT: Make sure to collect the salmon before it reaches 10/10 so you can maximize the amount of salmon production there is. If it hits 10/10, the bear will not produce more salmon until its collected. If you are quick enough, you can collect one after the other as you walk by, turn around to get the other side, in a circular motion and repeat. I typically started grabbing the first one when it hit 6/10 or 7/10. After 3.5-4min, their health will hit 0 and they will die, which also drops more loots such as bear talons, bear leather, meat etc which you can use to sell as well!
I basically caught 42 bears which takes about 30min-1hr depending how efficiently you are moving on your island (place campfires down and use your glider to navigate faster). There is also a short cooldown for the bears after you capture or kill them so rotating around the map in a large circle really helps. after that it took me about 16min to go through a stack of 42 bears and selling the salmon would net you barely under 2mil (in about 1hr 20min from catching to farming for every 42 bears).
Random oddities that are worth selling:*** Spoiler - click to reveal ***Sometimes random things like a supply pod or meteorite will appear on the map. If they do, always go for them. If its the supply pod, a great thing to make on the work bench is (2x) cloud storages:
- 10x Steel ingots
- 10x Titanium ingots
- 5x Electronic Circuits - (The supply pod drops 10!)
- 10x Sheep Wool
Creating this at a workbench and selling will net you $50,957 each which is still pretty decent. Another oddity are meteorites that fall to the ground. They will be a flaming ball on the ground and if you stand on it and click you should be able to collect it. I know there is a large one that goes for $10k and a medium that goes for $5k.
Leftover materials worth selling
- $9,840 - High Capacity Battery
- $38,448 - Fuel Tank
- $9,840 - High Capacity Battery
- $21,600 - Sword of the Dark Knight - (15 platinum ingots)
There is plenty you can sell, but I this is what I mostly stuck to if you are going for a more passive, not running all-over the place kind of grind. Took me a few hours of experimenting and this is what helped me knock out the 10mil pretty quickly! As soon as you upgrade the Age, the achievement will pop!
