Devotion ranks can only be earned after attaining level 6 in a class. For every 20 credits invested thereafter, the player gains 1 rank of devotion towards that class. Devotion ranks offer no in-game benefit other than showcasing your commitment to a certain class.
Devotion Favors
Players with at least one rank of devotion may carry a personal devotion favor, a belt favor, garment, or other item designed to represent the class they are devoted to. This favor may be adorned with a number of gold symbols to indicate the amount of favor the player has. For example, a player with 3 devotion ranks in bard might carry a musical instrument with 3 gold music notes. A player with 5 devotion in warrior might have a sword with a purple crossguard and five gold stars.
To keep the presentation options open for customization, devotion favors are not reserved symbols - players may still use gold symbols freely for other purposes, and it is up to the designer of each devotion favor how much or little they want it to stand out from normal garb and accessories.
