All characters (whether a roleplaying character or PvP character) will receive a Birthday Present every time the character's in-game /age accumulates a multiple of 12 months. The present will appear in the character's inventory the next time the player logs in to that character with at least 1 free inventory space.
The present will be identified as a <Nth> Year Birthday Present depending on how old the character is.
The content of the present is determined when it is created, not when it is opened.
Anomaly! The year is calculated as exactly 365 days. Thus, for each leap day that has occurred within a character's "lifetime," that character's birthday will occur 1 day earlier than their original creation date.
