Mist runes are combination runes. They count as two separate runes: one water runeand one air rune. Thus, any spell requiring one water rune, one air rune, or both will spend only one mist rune.
You may wear a tiara to enter and use the altar, but the other element must be a talisman when crafting combination runes. Clicking on the altar or using a pure essence on it will produce normal runes. To prevent creating the wrong runes, make sure you are using the complementary rune on the altar. For example, at the Water Altar use the air runes on the altar.
Combinations have a 50% success rate (or 100%, if the player is wearing a binding necklace), and the talisman is consumed in the process (unless the player uses the Lunar spell Magic Imbue). The elemental talisman will also not work in place of talismans when crafting the runes.
