The buff/debuff checklist is intended to help any raid lead keep track of all buffs and debuffs present in their roster. In general, a perfectly optimized raid group will have most, or even all of these buffs. That being said your ultimate composition will always be based on the content you're doing and the experience and ability of your group. Use this as a guide but understand that setups are very fluid even at the highest levels in ESO. Sources are generally listed from most common to least commonly used.
This list DOES NOT include buffs that are generally self-supplied (e.g. Minor Force).
KEY: Gear, Abilities (Tree/Class), Passives (Class), Consumables, Other
NOTE: You need either Minor Sorcery OR Minor Brutality based on whether your DPS are stacking spell or weapon damage, respectively. You need either Minor Prophecy OR Minor Savagery, but not both.
