Chaos Cubes are a one of the power systems in Lost Sword that give you flat stats to all the characters in your account. There are three different cubes at the moment:
At the moment the max level it’s 260, but developers update this every few patches.
You can “upcraft” cubes from one rarity to the next one at a ratio of 5:1.
It’s not really recommended to use this system a lot until you max out at least the blue cube.
The best way of farming cubes it’s using Stonehenge stage 3, since you can quickly dispatch all the enemies and just auto dismantle the gear into cubes.
The reason we use stage 3 instead of a higher one is simply because the rate of drops on normal enemies it’s the same at stage 3 or stage 7.
We are farming normal enemies, NOT BOSSES. If you want to farm bosses, always go for the highest stage you can clear for better gear.
These are the results of one hour of farming at stage 3. The first picture is before, second is after.
Assuming you already have your rare cube maxed out, that is a lot of extra levels you can craft for the heroic one.
Lastly, this method of farming will not only give you cubes, but also mystic stones, scrolls and A LOT of fairy powder thanks to the auto dismantle.
