↖ The Farming Rule That Actually Matters
Forget what's the strongest dungeon in the game. Ask this instead:
Can I clear it consistently? Does it drop what I need right now? Does it unlock my next upgrade?
If the answer isn't yes to all three, you're farming the wrong spot.
| Your Wall | Farm This | Material |
|---|---|---|
| Stuck in Frozen Valley | Trial | Painstone |
| Clearing Frozen Valley easily | Penitent | Turbonite |
| Stuck at Oath Lost Castle | Castle (safest difficulty) | Witherite |
| Clearing Castle reliably | Castle Inferno / manageable Hell content | Rotten Lotus / Heat Shells |
| High-end pushing | Purgatory / Inferno | Lineite |
↖ Frozen Valley: Painstone → Turbonite
Dying in harder Frozen Valley content? Farm Painstone. Don't force it — stabilize first.
Clearing Trial fast with zero deaths? Move to Turbonite, ideally from Penitent. Don't sit on Painstone once you outgrow it — you're wasting time.
| Clear Feel | Do This |
|---|---|
| Fast, low deaths | Farm Turbonite |
| Slow, frequent deaths | Back to Painstone |
| Only clears with carries | Solo lower difficulty first |
↖ Oath Lost Castle: Witherite Is Non-Negotiable
Stuck here? Witherite is your entire focus. Period.
It unlocks better armor, better weapons, and — most importantly — more reroll chances at usable substats. This isn't a detour. It's the foundation for everything after.
| Status | Do This |
|---|---|
| Can't touch Rotten Lotus yet | Farm Witherite |
| Weak armor rolls | Keep farming Witherite gear |
| Clears Castle, not Inferno | Farm safest Castle diff |
| Gear is solid | Test Rotten Lotus / Heat Shell |
Rule of thumb: farm Witherite until the next dungeon feels farmable, not barely survivable.
↖ Rotten Lotus vs Heat Shells
Rotten Lotus is the better long-term pick — if you can farm it without dying every run. Inferno-level Lotus punishes weak gear hard.
Heat Shells are the smarter grind when Lotus is eating your time. Farm them, get stable, then switch back.
Real talk: Castle-layout maps feel safer than open Inferno zones — more room to kite, fewer surround-and-die moments. A stable 5-minute clear beats a messy 15-minute one every time, even with a worse drop rate.
| Situation | Farm This |
|---|---|
| Lotus runs drag on | Heat Shells temporarily |
| Dying multiple times/run | Drop difficulty |
| Clearing Heat Shells fast | Use as stepping stone |
| Lotus feels manageable | Switch back |
↖ Lineite: The RNG Grind for Plague Gear
Lineite feels cursed. Drop rates are inconsistent, enemies hit hard, and the full Plague set takes a lot of runs.
| Situation | Farm This |
|---|---|
| Clearing Inferno fast | Inferno |
| Inferno is slow | Compare mats/hour before committing |
| Purgatory is stable | Purgatory — consistency wins |
| Can't farm it yet | Fix Witherite/Lotus gear first |
Treat this as a marathon. It's not a quick upgrade — don't force it early.
↖ Power ≠ Damage (Stop Getting Fooled)
Power is mostly HP. A player sitting at 130,000+ HP can flex huge power numbers while dealing a third of the damage of someone with lower power but better rolls.
If enemies aren't dying faster despite rising power, your problem is substats, not gear tier.
| Stat | Improves | Watch Out |
|---|---|---|
| HP/Power | Survival | Doesn't mean damage |
| Crit Damage | Burst | Useless without crit rate |
| Crit Rate | Consistency | Useless without crit damage |
| Attack Bonus | Overall damage | Scales with gear quality |
| Hell Mode substats | Long-term ceiling | Needs more farming |
↖ Best Substats to Chase
For most damage builds:
Critical Damage > Critical Damage > Attack Bonus > Critical Rate
A lower-power item with these rolls will outperform a higher-power item with junk stats. Every time.
| Substat | Priority |
|---|---|
| Critical Damage | Very High |
| Critical Rate | High |
| Attack Bonus | High |
| HP/Defense | Medium |
| Utility stats | Situational |
↖ Hell Mode Gear: Why It's Worth the Grind
Hell Mode isn't just a fancier item name. It's a higher stat ceiling — better rolls, extra substat bonuses, more room to optimize.
| If You're... | Do This |
|---|---|
| Clearing Hell Mode easily | Farm it constantly |
| Dying repeatedly | Drop difficulty |
| Missing specific mats | Target the exact drop dungeon |
| Got Hell gear, bad rolls | Keep farming — the item name isn't the goal, the roll is |
↖ What to Sell (Without Regretting It)
Simple filter: not Mythic, not Hell Mode, not needed for your next craft? Sell it.
| Type | Sell or Keep |
|---|---|
| Low-tier unused mats | Sell |
| Old-zone non-Hell mats | Sell |
| Mythic materials | Keep |
| Hell Mode materials | Keep |
| Mats for your next set | Keep |
Don't sell your way into a progression wall to save inventory space.
↖ Weapon Pick: Just Use Double Heavy
From actual play: double heavy weapons hit way harder than people expect. Slower, sure — but master the timing and it carries progression hard.
| Weapon | Strength | Weakness |
|---|---|---|
| Double Heavy | Big damage, reliable | Slow, timing-dependent |
| Bow | Safe range | Struggles with weak substats |
| Light | Fast playstyle | Needs uptime |
| Scythe/special | Fun patterns | Very quality-dependent |
If you're unsure, grab double heavy and pair it with crit damage/crit rate rolls.
↖ The Full Loop
1. Farm the best material you clear consistently
2. Upgrade the next armor/weapon
3. Check substats, not power
4. Move up only when it's efficient, not just possible
5. Sell outdated mats to fund the next step
6. Repeat until Lineite → Plague gear
↖ Mistakes Killing Your Progress
Farming too high, too early — a painful 15-minute clear loses to a reliable 5-minute one.
Ignoring substats — power is loud, substats are quiet, but substats are where the damage actually lives.
Selling the wrong mats — check if it's needed for your next armor, weapon, or Hell Mode craft before hitting sell.
Chasing leaderboard power — a lower-power build with better crit stats clears faster. Every time.
↖ FAQ
↖ What should I farm if I'm stuck in Frozen Valley?
Farm Painstone first. Move to Turbonite once Trial clears are fast and clean.
↖ What should I farm if I'm stuck on Oath Lost Castle?
Witherite. It's the core mat for better armor, weapons, and substat rerolls at this stage.
↖ Is Rotten Lotus better than Heat Shells?
Lotus is stronger long-term, but only if you can farm it without dying constantly. If not, farm Heat Shells and switch back later.
↖ Is power the same as damage?
No. Power often reflects HP, not damage. Crit damage, crit rate, and attack bonus decide your actual hit output.
↖ Is Hell Mode gear worth the grind?
Yes. It has a higher stat ceiling — stronger rolls and more substat bonuses than base gear.
↖ Summary
Farm what you can clear consistently, not what looks impressive. Painstone → Turbonite → Witherite → Rotten Lotus/Heat Shells → Lineite. Every step should unlock the next.
Power keeps you alive. Substats decide how hard you hit. Chase crit damage, crit rate, and attack bonus over raw power numbers — and don't sell your way into a wall.
