ESO buffs & debuffs — every source

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 56 are below.

Minor buffs & debuffs

How groups typically divide buff and debuff coverage

Because no buff stacks with a second source of itself, coordinated groups usually assign each major buff or debuff to a specific role rather than letting everyone try to provide the same one. Tanks and support builds commonly take responsibility for group-wide debuffs like Major Breach or Major Cowardice, while designated buffers cover things like Major Courage, Major Prophecy, or Major Savagery, freeing every damage dealer from needing to slot the same effect individually.

The number of sets versus skills that grant a buff is a useful signal for how to plan around it. Buffs with very few sources — often just one set or a single class skill line, like Major Sorcery — tend to be tied closely to a specific class or niche skill, so a build outside that class usually needs a group member or a different item combination to get it. Buffs with dozens of sources, like Minor Slayer or Minor Aegis, are easy to pick up from almost any gear choice, so they're rarely worth planning around carefully.

Before slotting a set or skill purely for its buff, it's worth checking whether your class kit, Champion Points, or a teammate already supplies that same buff. Since a duplicate source contributes nothing extra, confirming coverage first lets you spend that gear slot or skill point on damage, sustain, or a buff nobody else in the group is providing.

Common questions

Can a character have both the Major and Minor version of the same buff active at once?

Yes. Major and Minor tiers of the same buff (for example Major Brutality and Minor Brutality) are tracked as separate effects, so both can be active on the same character at the same time and their effects add together. The 'does not stack' rule only applies within a tier — a second source of Major Brutality while you already have Major Brutality is wasted, but having Minor Brutality alongside it is not.

What actually happens if two sources try to apply the same buff at the same time?

The buff itself does not double up — you don't get the effect twice. In practice the game keeps a single instance of that buff active and the redundant source either fails to reapply anything new or simply refreshes the existing duration. This is why the page's advice is to cover each buff with one dedicated source and use remaining sets or skills for something you don't already have.

Why do some buffs on this page show a dash (—) instead of a percentage or stat value?

Those are buffs and debuffs whose effect isn't a flat, single-number stat change — things like Defile and Vitality (which reduce healing effectiveness), Mending (which increases healing done), Brittle (which affects critical damage taken), or Enervation and Timidity (which alter critical chance). Their impact depends on context like healing amounts or crit interactions rather than a fixed Weapon Damage or Armor number, so they're listed by function rather than by value.
