Loyalty Bar Heart
Loyalty represents the level of a companion's bond to the player. It is represented by a bar of hearts, with maximum loyalty at 4 hearts and minimum at 0. Most party members begin with a loyalty level of 2 or 3. A companion who's loyalty drops to 0 will not automatically abandon you, but will require quick positive action to retain them as a member.

Loyalty influences how likely a locally-recruited companion is to stay with the party when an expedition ends. It may also influence the likelihood of companions deserting the party mid-expedition or immediately after an expedition. 

Low loyalty triggers a companion to become Angry and eventually Renounce the group. 

Companions with high loyalty may randomly present a small gift for you.
