# Tool Upgrades
By upgrading tools, a character’s chance of success can be increased. The rate of this increase also depends on the rarity of the tools. As mentioned, each tool has different attributes, such as speed, time, and reward multiplier. When any tool is upgraded, all three stats increase, but the rarity of the tool affects the increase rate.
Regardless of rarity, all tools are useful at their maximum levels. However, tools with higher rarities feature slightly better stats overall. On the other hand, rarity affects a tool's starting level.
To upgrade their tools, players need to have a sufficient number of Tool Cards and coins. The required amounts for the upgrade are as follows:
| Level | Gold Cost | Regular | Unique | Crypton |
|---|
| 1 | - | 1 | 1 | 1 |
| 1 to 2 | 2 | 2 | 2 | 2 |
| 2 to 3 | 4 | 5 | 4 | 3 |
| 3 to 4 | 10 | 10 | 8 | 5 |
| 4 to 5 | 25 | 20 | 15 | 10 |
| 5 to 6 | 50 | 50 | 30 | 20 |
| 6 to 7 | 100 | 100 | 50 | 32 |
| 7 to 8 | 200 | 300 | 100 | 45 |
| 8 to 9 | 500 | 750 | 200 | 50 |
| 9 to 10 | 1000 | 1000 | 500 | 100 |
| 10 to 11 | 2000 | 1500 | 800 | 150 |
| 11 to 12 | 3000 | 2000 | 1000 | 200 |
| 12 to 13 | 4000 | 2500 | 1250 | 300 |
| 13 to 14 | 5000 | 3000 | 1500 | 450 |
## Tool Cards
To unlock and upgrade their tools in the game, players must first obtain Tool Cards, which can be found in Tool Boxes with a specific pull rate as described in the [Tool Boxes](broken://pages/67bmo2qBgVpqFY70DwD6) section of this document.
As players collect more Tool Cards, they fill up a progress bar. Once they have collected enough Tool Cards, they use these cards to upgrade their tools.
