There are many cards in Legends of Runeterra, and each have their own stats and effects to make them unique. It can be overwhelming, especially if you’re new to the card game genre, to learn all these effects. That’s why we’re dissecting all the keywords in a series of guides. In this one we’re taking a look at Stun.

If you want to guarantee that an enemy unit doesn’t participate in the combat phase, Stunning them is the best way to do it. If a unit is on the board, ready to attack or block, and it gets stunned, it gets sent back to the bench—not to the owner’s hand. If an enemy is on the bench already, Stunning them simply prevents them from blocking or attacking in the same round.

Stun is a powerful tool, and one that’s very difficult to play against because there are very few tools to directly counter it. The Ionian card Deny can block any spell or skill that’s about to Stun, but other regions don’t have a similar ability. A workaround is by using Recall to withdraw a unit, and then play it again, though it’ll cost you a bit of mana. Below, we’ve listed a few cards that either Stun or work with the mechanic.
