Pre-inferno Ascension Tier 3 (level 130 - 200)[]

  • You can now move monster freely. and you should start farming Cards for each monster (except boss on every 5th stage) 100 Card Milestones for each monster should be your immediate goal.

Early Inferno level (level 200 - 400)[]

  • Congratulation on reaching Inferno Levels stage. This is where the real game start. You can now freely change monster Inferno Tier and is now under the effect of Nerf Rate, you will gain reduced exp, gold and card rate. If you don't contribute enough DPS to the party (10%, 6.66% and 5% for 2, 3 and 4 man party respectively)

  • You can also reset your Soul orbs unlocked with 10 crystal and unlock Ship Orb to help with arena challenge too.
  • Once you are done with Ship arena. Reset your Ship Trophies and put it into fuel generation and Expedition Increase.You need a lot of Expedition Points. Use the leftover Ultinum to level up Upgrade X (Fuel Station). Always go for Pet Food Expedition and reset your ship orb. You don't need it for a while.
  • Focus your Lab Upgrades on fish stick. Fish Value will increase your daily SO gain. Leftover point should go to Efficient Output and Ascension Points.
  • Use Trade Trophies to upgrade Fish jackpot.
  • Save diamond for the Fishing Boat (5k). Try to time it with fishing orb 3*. Fishing boat also give 100 additional fishing net. Don't forget to up min rarity when auto fishing. Each subsequent boat (up to 5) also grant additional 100 net for 1k diamonds. Abused this gain to upgrade your fishing orb to 4* if you can.
  • As a rule of thumb for Fishing upgrades go for Rod then Tackle until level 4 then start upgrade Tackle first while keep Bait and Tackle 2 levels below.
  • The only goal here is to get more level while trying to farm card on all mobs except boss

Newbie Inferno Hell (level 400 - 1000)[]

  • There is a major increasing in Experience needed per level after level 400. Most newbie give up at this stage of the game. This stage take months of playing to get though (even if you get carried, you still need to catch up on card and economic part)
  • Start finding a new guild such as booster guild for newbie if you have not join one already. There's a few player who offer to carry newbie through this stage. You can check IOU Discord for more info.
  • Start adding ascension point to Fish value, Mining yield and card drop yield.
  • You may consider getting Double card (250 diamonds - 7 days) buff and start putting P-Core in other lab upgrades (except click). Your lab upgrade at this point should look like this.Fish>Pet=Auto>Asc>Card>Click < 30. Keep in mind that at later stage of the game you will treat your auto lab upgrade the same way as click.
  • There are lot of things you can do to increase your DPS at this stage
    • Complete as many Challenges as you can including series challenge.
    • Farm card effectively. Move monster when you reach card milestone.
    • Do your Pet Arena with AP (set an AP limit for stage such as 500 AP max). Your arena damage is affected by

    • Upgrade efficient output Lab Upgrades (max 50)
    • Unlock more DPS orb
  • Find a permanent party member. Set a card goal with them and help each other move monster when you all reach card milestone. After all this is a multiplayer game, you won't succeed playing alone here.

Woodcutting Madness (level 1k+ Pre Stone Push)[]

  • Congratulations for reaching level 1k. You have now unlocked Legendary Upgrades. This is a good time to go Wood Build. You need
    • Woodcutting Damage and Log Gain Ascension (min 25)
    • Woodcutting Damage orb (5* or more)
    • Woodcutting NRG+ Ascension (Max 2)
    • Wood Damage Legendary (max 50)
    • Wood NRG Reduction Trophy (max 25)
    • You may consider upgrade personal sawmill to help.
  • It's always a good idea to use some dynamite for stone and crystal when you reach Depth Milestone to help speed up progress. you can consider it when Weekly Bonus is either Stone or Crystal or both. Do not overspend your AP on dynamite (should be less than 10k AP). Save AP for major stone push at 750 depth. You need
    • Ask for a higher Warehouse guild visit if you can.
    • Stone orb (at least 5*)
    • Mining Yield Ascension (max 25)
    • Dynamite Damage Trophy (max 25)
    • Upgrade Personal Warehouse (to your desired level) as often as you can when you push.

Late Game (750 Depth and Beyond)[]

  • Congratulation on getting 750 depth. You should unlock most of your Soul Orb by now. It's time to start working on 6* stone to prepare yourself for dynamite stone push. More info about it on Brief Guide For Pushing Made by Lili.
  • Dynamite reward is capped at 750 depth but the mining depth go beyond it. At some point stone from nrg will outscale dynamite gain. Highly recommended waiting for crystal bonus week before pushing as the amount of crystal gain from it will skyrocket your Virtue level and can be use to upgrade Fish Jackpot.
  • Skill in Arena ship building will made you go far in this stage. Read the ship guide within IOU Multicalc. Don't be afraid to try out a few builds. You can always reset your arena ship for 500 diamonds (7 days cooldown)
  • You should consider switching your pet upgrade map to critical build after T14 pet and 8m PP.
  • 750 depth player is highly sought out by most guild (even the top one). Consider changing your guild to a more competitive one if you want to go far in this game especially if you are decent at Shipbuilding.

Orb Acquisition Order[]

Orb unlocks can be reset for 10 crystals cost. Some orbs don't need to be on all the time such as ship arena and Mining Damage.

  • Fish Value - The most crucial orb. Help with your daily SO gain. Fishing lose its effectiveness pass 5* so keep that in mind. GET THIS ASAP.
  • Mining Damage - This give double damage just by unlocking. Also help with crystal gain. GET THIS ASAP.
  • Gold Rate - Gold is the most useful resource pre-inferno level. you will want to get this early but leave it as 2* and reset it out later when you reach inferno level.
  • Auto Damage - Auto DPS is a major DPS source pre T14 pet. its effectiveness is overshadow by pet that will become your Major DPS later. Get this early but leave it as 5*.
  • Ship Arena - This is the most important orb to have. Give bonus damage and HP to Arena Ship. Unlock and upgrade this to help with Space Arena. you can always reset it out for another orb if you don't have enough crystal. Get This ASAP.
  • Multi Catch - Chance for additional fish. Great orb to unlock at early stage. chance for 2x fish mean you gain double value from 1 fishing net (Can go higher than 2x). Also help with Pearls. Get this early and combine it with Fish Jackpot. Its effectiveness drop down on later stage.
  • XP - Additional Exp Bonus is always welcome. This will help you with your journey to level 1k.
  • Wood Damage - Middle game orb. Wood is used to unlock mining depth. Get this to help with your Daily wood gain. so you can unlock depth faster.
  • Stone Yield - Another middle game orb. Stone is a major resource use to upgrade Guild Building. you should consider getting it when you reach 100 depth. This is the first orb you should upgrade to 6* to prepare for Space-Stone Push loop.
  • Mining Critical - Nice addition to increase your daily stone and crystal gain.
  • Pet Damage - Middle-Late game orb. Pet will become a major source of your DPS later. also help with Pet Arena.
  • Card Yield - Pretty good orb for middle game where you should start farming card extensively. Combine this with Ascension Card Yield, Trophies Card Min Increase and Double Card Buff (more info on Cards) will net you nice amount of card.
  • Pet Training - Long term orb. combine it with Pet DNA splicing (Lab Upgrade) for some juicy training exp.
  • Crit Damage - Pretty good early game orb for DPS. Get this to help with your early game DPS. Leave it as 5*
  • Challenge Damage - Another good orb for middle game.Increase your Challenge Damage (both in Challenges and Series). Series Challenge is a major your source of DPS.
  • Expedition Pts - Another Long term orb. combine it with Expedition Increase Trophy for some juicy Expedition Points
  • Card Damage - Late game orb. Card Milestones give Based Damage which is used as a basic for all modifier.
  • Click Damage - You either get this early or don't get it at all. A pretty mediocre orb. Somewhat useful for series challenge where you tend to spec for click. The usefulness outside of that however is questionable.
  • Multi Attack - This suffer the same fate as Click Damage. A weaker version of Crit Damage. you either get this early or don't get it at all.
  • Wishing Well - This may not be as bad as people thought. Increase the effectiveness of Wishing Well investment but Wishing Well is a pretty weak building.
