In Teamfight Tactics, ever since augments were introduced back in Set Six, one of the best feelings is to acquire a rare Augment that changes the game completely. For me, it usually means that the Augment either fits perfectly for what I need or makes the game a lot more fun to play. That way, even if it leads to a loss, at least it was enjoyable in the end.
One of the best Prismatic augments that was both rare and fun was Level Up, which allowed players to get to level 10—a level higher than the usual maximum level of nine. Level 10 offers better unit rarity drop rates and an opportunity to swarm your opponents. Now, due to the addition of Legends in Set Nine, hitting level 10 is pretty common—and that bores me to no end.
