History Videogame / GemCraft

* FlawlessVictory: Defeating a map in Labyrinth without letting any enemy touch your gem gives an xp boosting medal for that round.

* SealedEvilInACan: The Forgotten is sealed away in the Gem of Destiny, but the mage from Chapter 0 is foolish enough to lust for it...and breaks it.

* ChainLightning: Lime gems can strike chain hits.

* SplashDamage: Red gems give splash damage in first two games. Lime gems give a multi-hit version (which is likely why red gems were changed.)

* ''Orange'': Mana Leech.
* ''Yellow'': Multiple Damage[=/=]Critical.
* ''White'': Poolbound. Increases the gem's damage and specials when the mana pool levels up.
* ''Red'': Chain hit (from lime, and moving it closer to its original SplashDamage role).
* ''Green'': Poison.
* ''Cyan'': Regeneration suppressing: lowers monsters' health regeneration rate.
* ''Black'': Bloodbound (from red). Increases the gem's damage and specials based on the number of monsters the gem has hit.
* ''Blue'': Slow.
* ''Purple'': Armor Tearing.

* '''[[color:orange:Orange]]''': Mana Leech. Each time it hits a monster, you gain mana.
* '''[[color:yellow:Yellow]]''': Multiple Damage. The first two games gave a flat rate to deal triple damage. In Labyrinth, the multiple damage rate can be ramped up as high as you can make it (starting with double damage).
* '''[[color:chartreuse:Lime]]''': Multi-hit. Starts with one extra hit, but can be ramped up to be able to hit more than two monsters.
* '''[[color:green:Green]]''': Poison. Ignores armor, so useful for armored waves as well as swarms.
* '''[[color:cyan:Cyan]]''': Shock. Can stop the monster in its tracks.
* '''[[color:blue:Blue]]''': Slow.
* '''[[color:purple:Purple]]''': Armor Tearing. Each hit lowers a monster's armor by a given amount.

* AllegedlyFreeGame: Gemcraft: Labyrinth contains a five-dollar "premium" version which unlocks extra modes, skills, and battlefields.

* RoyGBiv: The Gem colours are Red, Orange, Yellow, Dark and Lime Green, Blue, Indigo, and Violet.

* TheComputerIsACheatingBastard: The Shadow boss from ''Labyrinth''. It has the ability to spawn a HUGE ZergRush of units that will take a bite of time to take down... and there's a possibility that it spawns them ''right in front of your orb'', making it impossible to avoid massive damage.

* PlayerAndProtagonistIntegration: Type 2.

* MetalSlime: Apparitions in ''Labyrinth''. They [[AirborneMook fly over terrain]] slowly and have a TON of hit points, but they can't harm you at all and will just exit the map. However, killing these gives the player '''3 free skill points'''!

* LuckBasedMission: Every time you craft a gem, you get a ''random'' one based on those available in the level. The same goes for using Gem Bombs on enemy-spawning buildings- they may or may not destroy the building due to randomized damage.

** Red gems in ''Labyrinth''. They add a percentage of their kills to their damage. Meaning a red gem that's been there since the first wave can have a damage of over 1000 by the final waves. The gem won't dominate the game by itself, but becomes much more powerful when combined with the lime or yellow gems (which multiply the offensive power.)

* AllegedlyFreeGame: Gemcraft: Labyrinth contains a five-dollar "premium" version which unlocks extra modes, skills, and battlefields. The difficulty ramps up faster than your skills in the free mode to the point where it becomes nearly impossible to advance beyond the halfway mark without paying.

* AllegedlyFreeGame: Gemcraft: Labyrinth contains a five-dollar "premium" version which unlocks extra modes, skills, and battlefields.

* DangerousForbiddenTechnique: Labyrinth has a meta example: The glitch that allows the creation of near infinite strength gems has a chance of deleting your save file.

* {{Mana}}: This is needed to build things, craft gems, cast spells, and performs [[CastFromHitPoints double duty]] as hit points as well. It builds up slowly every second, but largely comes from monsters you kill, and gets increased by using orange gems in the right places.

** Red gems in ''Labyrinth''. They add a percentage of their kills to their damage. Meaning a red gem that's been there since the first wave can have a damage of over 1000 by the final waves and in fact out-damage gems of other colors several grades higher than it.

* SoundOfNoDamage: The game plays a metallic clink if an attack on an enemy is nullified by DamageReduction.
