Vampire Crawlers Gems: Blacksmith, Jeweller & Every Gem¶

Gems are Vampire Crawlers' equipment system: socket them into cards for permanent effects. Three systems control them: where to socket (Blacksmith), how often each gem drops (Jeweller), and the gems themselves. All 62: 58 at launch plus 4 from Death Parade, with real unlock conditions, below.

Americans spell it "jeweler", which is why you will see both spellings in guides — same NPC, same counter.

Count check: 62 gems in the official table: 58 shipped at launch and Death Parade added 4 (Adaptability, Afterlife, Scavenge, Switch). The table below lists all 62 with their published rarity and effect; where the wiki gives no unlock condition, this page says so instead of guessing.

The three systems¶

Socketing, the Blacksmith. Unlocked by the Stardust Anvil relic on the Teeny Bridge. Spend gold to add sockets to cards (1–3 per card). Cheap cards socket cheaply, 0-cost cards are the best socket targets since they're easy to play at the top of a combo. Until you unlock the Blacksmith, only weapon (red) cards and Tomes have sockets. The other relic locations are in the relics and Arcana guide.

Rarity: the Jeweller. Unlocked by the Lapidary Loupe relic in Gallo Tower (the sixth zone), and reached through the second counter inside the Blacksmith. Spend gold to move gems down the rarity ladder (making them drop more often) or seal Ultra Rares you never want to see:

Sealed → Ultra Rare → Very Rare → Rare → Uncommon → Common

• Taking a gem from Common all the way to Ultra Rare costs ~250,000 gold: a true endgame money sink, and that is exactly what the gold farming route pays for.
• Sealing (Ultra Rares only) removes a gem from your runs entirely. Seal the niche ones first: Mild (always breaks combo) is the classic candidate. Unsealing is always possible.
• Boss chests already bias toward rare gems, so don't waste gold making Evolution common.
• In Endless Mode, all gems drop at their default rarity: Jeweller tweaks don't apply (why the mode turns the Jeweller off).

Acquisition. The Gem Hammer relic (Mad Forest, the first zone) unlocks gems as a whole. After that: gems appear in chests and level-up rewards (taking a gem instead of a card keeps your deck thin), and you can cash out chest gems for 200 coins.

Which gems to chase first¶

• Evolution (free with the Gem Hammer): the whole meta. Boss chests bias toward it already.
• Draw / Amount / Double Damage (Mad Forest unlocks): plain, combo-agnostic value.
• Fireproof (Curd Refinery): turns your destroyed-on-use Wild cards permanent. Combo engine fuel.
• X Mana / Echo / Magnetic (Rare): the deep combo tools for late-game best builds.
• Decimate / Coin Count (Ultra Rare grinds): the Red Death kill conditions.
