Xerath makes Ascendant Charms show up in your shop. After each player combat, your odds of seeing one increase by 8% up to a maximum of 40%. Once you buy one, your odds reset.

Use the Arcana signifier item to choose a High Arcana champion. Arcana's effect changes based on the High Arcana you chosen.

• Ahri: Your team gains Ability Power for each 3-star champion.
• Hecarim: Champions holding items gain damage reduction and Attack Damage.
• Tahm Kench: Your team gains Health for each active trait.
• Xerath: Abilities deal bonus true damage for each Charm purchased this game.
• Emblem: Your team gains bonus damage for each fielded champion holding a Spatula item.

The Arcana's effect increases with every activated synergy threshold.
