Emblem bought or reward
Use the Emblem
The Title Ability
Emblems are given as a reward from quests or can be bought. On activation they grant a title ability to the player. With the update A Bitter Wind emblems got recreated with abilities of the same name. Right clicking the emblem and select "use" to receive the title abilty, the emblem vanishes to safe space in vault and inventory. Some titles add boons to various skills, using the ability adds the title to the characters name.
