The Lost City of Un’Goro Key Art

New Mechanic – Kindred

Elemental minion type was first introduced in the original Journey to Un’Goro back in 2017. Their unique mechanic is getting an extra effect if you played an Elemental last turn. It means that chaining together Elemental minions was very important, otherwise you might have missed on some powerful bonus effects.

The new “Kindred” keyword works exactly the same, but for all minion types. For example, if you play a Beast with Kindred (such as Ravasaur Matriarch), it will follow the same formula but for Beasts (“If you played Beast last turn, do X”).

And that’s not all – Kindred also works for spell schools. For example, the new Kindred spell Gravedawn Voidbulb will cast twice if you played a Shadow spell on previous turn. We had a few decks focused on a specific Spell School in the past, but they were quite rare overall; this new keyword might change that.

Returning Mechanic – Quests

Quests are making a return! Also dating back to the original Un’Goro, the last time we saw them was in Saviors of Uldum expansion in 2019. Quests are 1-Cost spells that always start in your hand. Each Quests asks you to do some task; after you finish it, you get a powerful reward.

Unlike Questlines from United in Stormwind, Quests are “one and done” – there are no multiple steps. But remember that you need to play the Quest from your hand first for the progress to count.

Each class is getting one new Quest in The Lost City of Un’Goro. So far, both of the Quests revealed follow the original formula – they reward you with a 5 mana 8/8 with a powerful effect. We don’t know whether other Quests will also do the same, but it’s very likely.
