In Hearthstone when a Kobold Geomancer is played the minon's summon is "You no take candle!". What is being referenced by this exclamation?
It's a reference to the Kobolds in World of Warcraft, as they only had a single candle, and they were scared you would steal it. It's a statement of defiance, "You NO TAKE CANDLE!"
In German mythology Kobolds were spirits that would haunt a home. Wikipedia: Although usually invisible, a kobold can materialize in the form of an animal, fire, a human being, and a candle.
WoW is just paying homage to the mythology of the Kobold - probably to help people realize, before WoW got as big as it did, that the creature was NOT "stolen" from D&D.
