Every time you cast a buff of a debuff on a character, they get an effect added to their list of buffs and debuffs (see HOWTO: Identify Buffs Using Textures for a guide on how to query this information). Following is a list of spells and associated queriable effects (these are texture names). The initial ones were collected by Pholus and a lot of the initial research into these came from Zorlens Hunter Libraries [1]. Please add more values. This can be useful because it will not require an update when the Rank value changes.
