Tome of Traits

The Tome of Traits is a special unit that occupies a bench slot in Teamfight Tactics. When you sell it, it opens an emblem Armory offering a selection of trait emblems, and you pick one to keep. The choices are tailored partly to the units you currently field.

Because emblems let a champion count toward an extra trait, a Tome can unlock a powerful synergy or push you to a higher trait breakpoint. It typically comes from augments and special orbs rather than the shop. Deciding which emblem to take, and whether the synergy is worth committing to, can reshape your entire board and final placement.
