Farming gems quickly as a free-to-play player in Soul Knight requires pairing zero-risk daily lobby claims with high-yield dungeon clears. You do not need to spend real money or forge costly weapons to build a massive gem reserve. By harvesting recurring garden plants, clearing the Officer’s daily task board modifiers, and running Badass Mode or Boss Rush with budget characters, you maximize gem payouts while keeping your crafting expenses at zero.

Step 1: Collect Free Lobby Gems Every Day
Before entering the dungeon portal, collect all available currency across the lobby. These interactions carry zero combat risk and supply a consistent daily baseline.
- Cultivate Gem Trees in the Garden: Prioritize planting Gem Trees over single-harvest crops. While a Gem Flower yields a single lump sum and disappears, a mature Gem Tree yields gems every day as long as you water it. Keeping two or three plots filled with Gem Trees creates an automated daily income stream.
- Inspect the Task Board: Check the board next to the Officer to accept daily bounties. These award direct gem payouts for defeating specific enemies or finishing designated stages.
- Watch the TV Merchant: Interact with the television in the living room to watch brief promotional ads for instant gem payouts.
- Check the Mailbox and Courier Cat: Claim any administrative rewards, event bonuses, or update compensation delivered to your mailbox.

Step 2: Clear Daily Officer Challenge Modifiers
The Officer's Task Board updates each day with four random gameplay modifiers and awards a large bonus gem payout upon defeating the 3-5 final boss.
End-of-run gem payouts scale with your monster kill count and unspent gold coins. Modifiers that increase enemy presence directly boost your final gem tally.
| Challenge Factor Type | Favorable Farming Modifiers | Modifiers to Reroll |
|---|---|---|
| Monster Density | More enemies in rooms | Elite monsters appear more frequently |
| Boss Encounters | Double boss spawns | Badass stats applied to normal enemies |
| Hero Mechanics | Halved skill cooldown, increased fire rate | Reduced maximum health, fixed 1 HP cap |
| Weapon Constraints | Infinite energy | Slower attack speed, restricted weapon slots |
"More enemies in rooms" raises the monster population in every stage chamber, significantly increasing gold and kill-conversion gems. "Double boss" spawns two bosses in boss chambers, doubling boss item drops and end-run credits.
If the board rolls severe survival debuffs—such as the 1 HP cap or sluggish attack speeds—use your daily free reroll at the board. Failing a run on floor 1-4 yields almost no gems and wastes time.

Step 3: Run Badass Mode and Boss Rush
Once you can comfortably clear standard dungeons, transition to high-multiplier modes to increase your hourly earnings.
Badass Mode
Badass Mode increases enemy health, fire rate, and elite spawn frequency. However, it applies a substantial multiplier to your final gem conversion. Because elite enemies drop high quantities of gold coins, clearing Badass rooms leaves you with a large gold surplus. At the end of the run, your unspent gold converts directly into gems. A single successful Badass run yields considerably more gems than multiple regular runs.
Boss Rush
Boss Rush skips standard mob chambers entirely and sends you through consecutive boss arenas. This cuts clear times down to a few minutes while guaranteeing high gold drops and boss-tier completion bonuses.
- Prerequisite: Entering Boss Rush requires a Valkyrie Feather. Stockpile feathers from daily task board rewards or standard stage clears before using Boss Rush as your primary farming loop.

Step 4: Pick Low-Investment Characters and Budget Loadouts
Net gem profit depends on keeping pre-run crafting expenses at zero. Spending gems and rare materials at the Forge Table or Design Table before entering a run reduces your net earnings.
Two free-to-play characters excel at clearing stages using only starting gear or floor drops:
- Knight (Dual Wield): The default Knight possesses high base armor and health. Dual Wield doubles your fire rate and offensive output during dense elite waves, allowing you to clear rooms quickly with standard floor-drop weapons.
- Alchemist (Poison Gas): The Alchemist provides exceptional area-of-effect crowd control. The baseline poison flasks slow enemies and deal heavy damage over time, letting you eliminate large swarms safely without crafting high-tier weapons.
Enter the portal with standard starter weapons or low-tier green blueprints. Upgrading starter weapons or picking up weapons inside the dungeon ensures that every gem earned at the victory screen is pure profit.

Step 5: Avoid Common Gem Traps
Maximizing your account's progression means directing gems toward permanent upgrades rather than consumable sinks.
- Skip the Gachapon Machine: Spending gems on the lobby Gachapon machine rarely pays off early. Its drop table heavily favors single-use materials and low-tier items over permanent blueprints or character unlocks.
- Prioritize Permanent Lobby Upgrades: Spend your initial gem earnings to max out your primary farming character, upgrade the Safe (which permanently increases starting dungeon gold), and level the Pet food bowl.
- Do Not Buy Mid-Run Revives: Soul Knight offers one free revive per run by watching an ad. If you die a second time in a run that is already going poorly, do not spend gems to revive. Take the partial completion payout, exit to the lobby, and start a fresh run.

This saved me time in the early game.
I wish I had read this before upgrading the wrong thing.
Nice guide. I am checking the other Soul Knight articles next.
The tips are practical and easy to follow.
