FAQ
What does Master Architect do?
Master Architect is a Trial set with 4 bonus lines. At 5 pieces, its top bonus is: When you use an Ultimate ability while in combat, you and the closest 5 group members within 28 meters of you gain Major Slayer for 1 second per 10 Ultimate spent, increasing your damage done to Dungeon, Trial, and Arena Monsters by 10%. See the full table above for every piece tier.

How the Slayer bonuses on Master Architect interact
Master Architect's core identity comes from two linked buffs: Minor Slayer, which is always active once 3 pieces are equipped, and Major Slayer, which is a stronger version triggered at 5 pieces whenever the wearer spends Ultimate in combat. Both buffs increase damage done specifically to Dungeon, Trial, and Arena Monsters, meaning they have no effect on damage against other players in PvP.
The 5-piece effect is notable because it is a group-support mechanic rather than a purely personal one: when the wearer spends Ultimate, the closest 5 group members within 28 meters receive Major Slayer alongside the wearer. The duration scales with how much Ultimate was spent, so builds that regularly use large or frequent Ultimate abilities will keep the group buff active more consistently than builds that rarely use Ultimate.
Since Master Architect drops from Halls of Fabrication in Vvardenfell and has no perfected version, farming it means running that specific trial repeatedly on any difficulty that drops the set, without a higher-quality variant to chase afterward.
Common questions
Does Master Architect's Major Slayer stack with its own Minor Slayer bonus?
Yes. Minor Slayer and Major Slayer are different buff tiers, so the 3-piece Minor Slayer (always active) and the 5-piece Major Slayer (triggered by spending Ultimate) both apply their damage-to-Monsters bonus at the same time while Major Slayer is up. When Major Slayer's duration runs out, you fall back to just the Minor Slayer uptime from the 3-piece bonus.
How is the duration of Major Slayer from Master Architect determined?
The 5-piece bonus grants Major Slayer for 1 second per 10 Ultimate spent when you use an Ultimate ability in combat. This means bigger Ultimate abilities, or activating Ultimate more often, produce longer uptime, and the buff is shared with the closest 5 group members within range rather than just the wearer.
Can Master Architect be used outside of Trials, such as in dungeons or arenas?
Yes. Although Master Architect drops in a Trial (Halls of Fabrication), its Slayer bonuses apply to damage done to Dungeon, Trial, and Arena Monsters, so the set functions the same way in four-player dungeons and arena content as it does in a trial, as long as the target counts as one of those monster types.
