What One Jewel Costs, and What Six Cost
The jewel calculator tells you what it costs to get from where you are to where you want to be. That is the right question once you have decided. This is the question before it: what does the whole thing cost, and where does the cost sit?
Every figure below is computed from the level table that drives the calculator.
One jewel, level 1 to 40
| Levels | 40 |
| Jewels | 6,731 |
| Essence | 1,154 |
And there are six slots — Ruby on Weapon and Helmet, Sapphire on Belt and Clothes, Topaz on Accessory and Boots. Maxing all six is 40,386 jewels and 6,924 essence.
Essence does not start until level 21
Half the ladder costs no essence at all:
| Reached level | Jewels | Share of the jewel cost | Essence |
|---|---|---|---|
| 10 | 325 | 5% | 0 |
| 20 | 1,205 | 18% | 0 |
| 30 | 2,521 | 37% | 234 |
| 40 | 6,731 | 100% | 1,154 |
Levels 1 to 20 cost zero essence. If essence is your constraint rather than jewels, everything up to level 20 is free of it, on all six slots.
The last ten levels are 63% of the cost
Getting from level 30 to level 40 costs 4,210 jewels — more than the first thirty levels put together, which come to 2,521.
Put another way: the jewels that take one slot from 30 to 40 would take a second slot from 1 to 34.
That is the number to weigh before committing. Six slots at level 30 costs 15,126 jewels. One slot at 40 and five at 30 costs 19,336 for the same six pieces of equipment — 28% more for one slot ten levels higher.
What this does not tell you
The table has costs, not value. Whether the stats at level 40 justify 63% of the ladder depends on what the jewel gives and on what you are building for, and that is not something a cost table can answer. The jewel tool shows the stats per slot; this guide only shows the price.
