Special loot farm area?

[valodyjb]

Is there a spreadsheet or a guide that can tell you the best places to farm special loot? (nature crystal, mana shards, red chili, etc..) I know bestiary gives a good chance at getting them but loot time is pretty long for me right now.

For a bit of more information, I just unlocked A rank gear and I'm trying to level my hero sword, and it requires a ton of Nature Crystal. I have no clue where to farm them, it's been 2 days and I've gotten maybe 200 and it cost 150+ for each level i want to upgrade.

Any advice is appreciated, thanks.

Edit: Ty for all the replies, specially Darnavir for a lengthy and thorough response. I understand that there is no definitive answer and that loot varies greatly (beyond whats guaranteed), but getting a general direction to point my afk farming towards is really helpful and I appreciate it.

The droprate of these is so low, that you should focus more on other loot instead. At your point you will get more result from farming monster fluid for leveling the items of the ranks below. And while you get these you will still get the special loot. Don't focus too much on hero sword alone. It upgrades really slow and will be gone after next reincarnation anyways.

No guide as far as I know and there's no area quickly dropping tons of them. Look for places spawning many monsters dropping your chosen items. You want places that drop both normal useful loot and your rare loot. Some areas can satisfy these conditions.
As far as your described items go:
Red chilli is dropped only by stepping on red chilli patches on 1-4, 6-2 and slime dungeon. Depending on your skills, speed, gear and damage, you might randomly stumble on them as you afk clear the levels.
Mana crystals are gained mostly from bosses and black foxes - 5-7 and clear levels dropping them.
Nature crystals would be 5-3 (slimes, foxes and bats), 5-7, 7-1, 7-2 (fishes).
Frost crystals would be 4-3, 7-1, 7-2, possibly 6-3.
Lightning would be probably 5-3 (again slimes, foxes and bats).
Gold crystals/shards tend to drop from some challenge bosses (nowhere shown, independent on normal drops), 6-7 (many orange magic slimes) and again 5-3.
Flame shards would be 1-7, 2-7, 3-7, 4-7, 5-7 or dungeons of these areas. Generally these areas with most red monsters.
White fox pelts, fox cores and fox hearts are from 5-7 (or fox dungeon).
For fish parts, probably 7-7, 7-5, 7-6 if you can't clear 7-7 fast enough. Tails, cores and chests are mostly nonexistent before this.
Anything dropped by challenge bosses can be gained by farming them.
Fairy coins are from 4-7 or fairy dungeon (purple fairies).
Enchanted cloth is mostly from 4-1 to 4-6, some is gained wherever are fairies or magical slimes.
Oil of slime is from any place with slimes. 1-7, 6-7, slime and magical slime dungeons drop significantly more (purple slimes).
Black pearls shouldn't be a thing - power of replication should make farmed challenge bosses drop more that you can spend.

Overall:
5-3 has great loot (nature, lightning, gold, fox pelts, bat parts, slime parts, enchanted cloth, spider silk) - everything dropping there is useful.
5-7 is good for fox tails, cores, hearts, nature, flame, some frost, quite many carved idols/relic stones.
7-7 is good for fish parts (certain A rank equipment needs them), 7-5 or 7-6 can be used instead
4-3 is about the best gold farming spot for a while. Also great for enchanted cloth, lots of frost crystals, some fairy coins, lightning, gold and nature crystals.
4-7 is good for fairy coins. There are also flame shards, nature, lightning, gold shards/crystals and enchanted cloth.
7-1, 7-2 are good for frost crystals + nature crystals. Keep in mind that other drops will be just fish scales and monster fluid (a decent amout).
Dungeons are mostly filled by highest tier monsters of their type. Great for their drops, not so good otherwise.
Challenge bosses for whatever they drop (even if it is dropped elsewhere).

The amount of loot gained varies during progression so much, that no guide is working for everyone. Even without many change the outcome varies. Here i made a comparison of the outcome of 7-7 loot under 4 different circumstances just a few minutes apart. Even these 4 trials are not comparable at all.

Note:
-there is a negative impact of salve of drop on common items and the positive impact on rare items. (Salve of drop run is with full skills and items)
-time required to pass a level lets the loot vary. Drop slot mechanics are the reason.
-Items and captured monsters influence the loot. Also area mastery does.

Thanks for the good tips I didn't even notice the chili floor tiles in the dungeons.

Has anyone come up with a method to auto farm the chilis from the slime dungeon? I notice that on my warrior if I remove the fan swing skill it is more likely to move on the chili spot while engaging the slimes for a while but by wave 300 or so it begins to become too difficult to kill the monsters quickly and then they move too far down which means I miss the chili anyways.....getting way farther to wave 1000 and beyond but just want to farm chilis without having to manually move.
