The Bone Shop in Blood Dungeon contains several permanent upgrades, but not all of them are available immediately. Some unlock naturally while playing, while others require completing specific objectives such as opening chests, destroying tiles, upgrading weapons, or surviving for a certain amount of time.
Here is how to unlock every Bone Shop upgrade in Blood Dungeon.
All Bone Shop Upgrade Unlock Requirements
| Upgrade | How to Unlock |
|---|---|
| Hearts | Heal for 100 Hearts |
| Guiding Lights | Open 100 Chests |
| Rerolls | Use 100 Rerolls |
| Weapon Slots | Spend $1,000 at Money Cages |
| Jump Height | Heal for 100 Hearts |
| More Money | Upgrade the Webs Weapon to maximum level |
| Shop Stamps | Spend $200 at Money Cages |
| Drop Site Stamps | Recover 3 Weapons from Drop Sites in a single run |
| Slower Enemy Projectiles | Destroy 10,000 Tiles |
| Luck | Upgrade the Lucky Spell to maximum level |
| Jumps | Survive for 13 minutes |
Most of these requirements are straightforward, but a few upgrades can take significantly longer to unlock.
How to Unlock Slower Enemy Projectiles
To unlock Slower Enemy Projectiles, you need to destroy a total of 10,000 Tiles.
This is one of the more grind-heavy Bone Shop requirements. The Tomb map is a good place to work toward this objective because it gives you plenty of opportunities to destroy tiles during your runs.
You probably will not finish this requirement immediately, so keep breaking tiles whenever possible while progressing through normal runs.
How to Unlock Luck
The Luck upgrade requires you to upgrade the Lucky Spell to its maximum level of 8.
This can be difficult because you first need the Lucky Spell to appear and then continue finding enough upgrades to reach Level 8.
A useful strategy is to play on the Boiler map.
The Boiler map makes it easier to reach the available Drop Sites quickly. Since there are only four Drop Sites, you can move between them efficiently and repeatedly search for opportunities to get the Lucky Spell.
To improve your chances:
- Use Charms that increase your money.
- Save money for rerolls when necessary.
- Fill your four weapon slots quickly.
- Fill your four spell slots quickly.
- Cycle through the Drop Sites as efficiently as possible.
Having your slots filled can help reduce the number of unwanted options appearing while you search for the upgrades you need.
Even with a good strategy, unlocking this upgrade can take some time because getting the Lucky Spell and all eight levels still depends partly on RNG.
How to Unlock Jumps
To unlock Jumps, you need to survive for 13 minutes in a run.
The easiest way to approach this is to focus entirely on survival instead of rushing to finish bosses immediately.
When you reach the final boss of an area, avoid killing it right away if you still need more time. Stay alive while continuing to dodge attacks and build up your character.
The Boiler map strategy can also help here because quickly collecting weapons and upgrades can make your character much stronger before you start focusing on survival time.
Once your build is powerful enough, surviving for the full 13 minutes becomes much more manageable.
How to Unlock Drop Site Stamps
For Drop Site Stamps, you need to recover three weapons from Drop Sites during the same run.
Drop Sites are easy to recognize once you know what to look for. They are pedestals surrounded by a circle of stones, with a chest in the middle.
Make sure you collect weapons from three separate Drop Sites before your run ends.
Fastest Way to Unlock the Bone Shop
Many Bone Shop upgrades will unlock naturally as you continue playing. Opening chests, healing, spending money, and using rerolls will gradually complete several requirements without requiring a dedicated farming strategy.
The upgrades that may require the most focused effort are:
- Slower Enemy Projectiles – Destroy 10,000 Tiles.
- Luck – Max out the Lucky Spell to Level 8.
- Jumps – Survive for 13 minutes.
- Drop Site Stamps – Recover three weapons from Drop Sites in one run.
If you are specifically trying to complete everything, alternate between normal progression runs and dedicated farming runs for these harder objectives.
The Boiler map is particularly useful for farming Drop Sites and building powerful runs, while the Tomb map is a solid option for working toward the tile destruction requirement.
With all of these requirements completed, you should be able to unlock every available upgrade in the Blood Dungeon Bone Shop.
