Teamfight Tactics explores magic, portals, and bees with Set 12, Magic n' Mayhem, adding a new layer of strategic depth to the Charms mechanic.

These new purchasable spells, which appear in every other store slot, offer a wide range of effects, from economic boons to battlefield disruption. They’ll be sprinkling a little magic across all TFT games starting on Wednesday, July 31. But of the over a hundred Charms in Magic n’ Mayhem, one reigns supreme: The Magnum Opus. Literally translated as “Great Work,” the Magnum Opus is the most powerful Charm in Set 12, according to developers Riot Games, but it comes with a hefty price in both gold and blood.

For 99 gold and a risky 66 health, Magnum Opus grants players a permanent three-star, five-cost champion—essentially giving them a golden ticket to victory. Other Charms, however, are less costly and collectively more powerful than the Magnum Opus.

The Arcana Charms are locked behind the requirement to deploy Xerath, a five-cost unit, but offer similarly devastating effects as the Magnum Opus. As their name suggests, the Arcana Charms are all named after a tarot card, such as The Tower, which offers a giant lightning dummy to bolster your defenses. Another powerful Arcana Charm is The Moon, which increases the player’s chance of finding a five-star cost champion by four percent.
