Do ESO buffs of the same name stack?

No. Two sources of the same buff (such as two sources of Major Sorcery) do not stack — the second is wasted. That is why it pays to know every source: cover a buff with one set or skill and use the rest of your build for something else.

ESO buffs & debuffs — every source

Q: What's the difference between Major and Minor buffs in ESO?

Major and Minor are two tiers of the same buff — Major is the stronger version (for example Major Brutality boosts Weapon Damage more than Minor Brutality). Neither stacks with another source of the same buff, so one source of each is all you need.

The query no guide answers cleanly: what gives Minor Slayer? every source of Major Brutality? Here's every set and skill that grants each buff — cross-referenced straight from the datamined text.

Major vs minor buffs

ESO buffs come in Major and Minor tiers (Major Brutality boosts Weapon Damage more than Minor Brutality), and a buff does not stack with another source of itself — a second source of Major Sorcery is wasted. So the whole game is knowing every source: cover each buff once, and spend the rest of your build elsewhere. All 61 are below.
