How to unlock all gems in Vampire Crawlers

Where to find all gems and how to get additional gem slots Gems in Vampire Crawlers: The Turbo Wildcard from Vampire Survivors are the best way to buff your cards. You think a Death Spiral hits hard? Imagine what a Death Spiral with a Double Damage gem can do. But although the gem system is easy to unlock, some gems are difficult to collect, especially the Uncrackable one. Here's how to use gems, plus a list of all gems in Vampire Crawlers, their effects, and how to get them. Gems are unlocked once you've found the Gem Hammer relic in the Mad Forest (the first dungeon after the tutorial). From that moment onward, you can open treasure chests to pick one of three random gems (sometimes four, based on your Luck stat). Place the gem on a card with a gem slot to add the gem's effect to that card. All attack cards and the rarer Tome cards come with one gem slot by default. For example, if you place a Might gem on a Knife card, playing that card will not only deal 40 damage (its base effect) but also increase your Might stat by 10% for that encounter. If you play that card again, you will receive another 10% Might. Beware, however, that you can't remove gems from cards. Since evolutions
