Jewels

Learn these eight and you understand half the game's economy.

Jewel What it does Where it comes from
Bless raises an item +0 to +6, never fails event bag · starting vault
Soul raises +7 to +9, never fails event bag · starting vault
Life adds life to the item event bag
Creation ingredient for expensive mixes event bag
Chaos base of nearly every Chaos Machine recipe drops from monsters, 0.1%
Guardian protects the item from vanishing on failure event bag only
Gemstone becomes Harmony Kanturu 3 only
Harmony special option on the item event bag only

Only Chaos drops from common monsters

The other seven come from events. That's what makes them expensive — and why Blood Castle, Chaos Castle and the invasion matter even when the item that comes out is junk.

Bless and Soul never fail here

From +0 to +9 you climb without risk. From +10 up the chance drops and the item can break — at that point the climb leaves the jewel's hands and moves to the Chaos Machine.

That's where the Jewel of Guardian comes in: it saves the item when the attempt fails. Don't push a good item without one.
