TFT Set 18: The Mischievous trait draws attention with its unique "Nunu riding" mechanic.

The Mischievous trait is quickly becoming a fan favorite in TFT Set 18 due to its ability to summon a "huge buddy", letting players mount a champion and completely shift the way battles play out.

Mischievous features a unique BFF (Big Furry Friend) mechanic.

The Mischievous trait comprises Kobuko, Veigar, Teemo, Tristana, Rammus, and Gnar. Its standout feature is the ability to summon a unit named Big Furry Friend (BFF), resembling Nunu. This is among the most intriguing traits in TFT Set 18.

Players can mount a Mischievous champion on the BFF, transforming it into a "rider". From then on, Nunu and the selected champion function as a two-in-one unit, boosting both survivability and damage output.

With 3 Mischievous active, the rider receives 15% bonus Health and 15% Attack Speed. At 5, these bonuses increase to 30%, and 50% of BFF's ability effects are applied to the mounted champion. Reaching 7 Mischievous raises the stat bonuses to 45% and transfers all of BFF's effects to the rider.

BFF adapts its combat role depending on the chosen carry.

A key factor in Mischievous's versatility is that BFF's skill varies depending on whether the rider is a ranged or melee champion.

If you pick a melee carry, BFF becomes more durable and charges into battle. On the other hand, if the rider is a ranged champion, BFF switches to a damage-support role, enhancing the backline's power.

This allows players to adapt BFF as either a frontline "shield" or a damage-boosting tool for the carry, based on the situation.

Veigar stands out as a potential carry.

Within the Mischievous roster, Veigar is drawing high praise on the test server thanks to his ability to stack Ability Power consistently with each takedown.

If Veigar shows up early and gets upgraded easily, he can become a powerhouse damage dealer in the late game. Tristana and Rammus are also standout picks for reroll compositions.

Furthermore, Mischievous can synergize with numerous traits such as Bruiser, Sorcerer, Guardian, Hunter, or Woodland, allowing players to easily pivot their composition depending on the items and champions they get.

Thanks to its distinctive BFF mechanic and high adaptability, Mischievous is set to become a trait that is both entertaining and viable in TFT Set 18.
