Anu White Dye Guide: ESO Seasoned Monster Slayer

The Anu White dye is the prize behind the Seasoned Monster Slayer achievement, introduced in ESO Update 50 alongside the new overland Challenge Difficulty system. It is a luminous white-gold iridescent dye. It looks absurd. It is, objectively, worth suffering for.

To get it, you must complete five sub-achievements by slaughtering specific monster categories in challenge difficulty mode. Each sub-achievement also unlocks its own iridescent dye, so you walk away with six total. Every single one is account-wide on unlock.

Important: Kills only count on Seasoned difficulty or higher. If you are on Adventurer, every kill does nothing toward these achievements. Set your difficulty before you touch a single mob.

The Five Sub-Achievements

ESO Update 50 finally gave the overland content the difficulty it should have had a decade ago. The ESO overland difficulty system adds four tiers, each applying a personal debuff to your character. Enemies do not get tankier: you just become progressively more pathetic.

For this grind, stay on Seasoned. Master and Vestige qualify but add zero benefit: you will just die more, and each death costs you time. The kills count equally across all eligible tiers. Do not be a hero.

Challenge Difficulty is per character, not account-wide. Set it on the character you intend to grind on before you begin. You will feel stupid if you realize three hours in that you were on Adventurer.

Grind Order & Best Locations

Complete these in the order listed. Each step feeds into the next, or at least does not waste your time.

Seasoned Construct Slayer: 500 Dwarven Constructs
Go to Bthanuel in Deshaan (west of Mournhold: the overland location, not the delve). It has ~29 Dwarven Spiders that respawn in ~90 seconds. Only spiders here: no centurions, no spheres, no swarming variants that count as a single kill. Clear, repeat, done in 18 runs.

~30 min

Seasoned Daedra Slayer: 6 of 8 Daedra types
You only need 6 types: read the tooltip. Recommended: Beastial, Humanoid, Flame, Storm, Frost, and Air or Flesh Atronachs. Full breakdown below.

~90 min

Seasoned Humanoid Slayer: 500 humanoids + goblins + giant-kin
By this point you will already have a head start. Crimson Cove (public dungeon, Malabal Tor) for humanoids. Tooth Small Gully (Orodon) for goblins. Kerakdena delve (Greenshade) for ogres.

~60 min

Seasoned Nature Slayer: All 7 categories
The hardest one. No skipping categories. Multi-location affair. Full breakdown below.

~90+ min

Seasoned Undead Slayer: Skeletons, zombies, ghosts, vampires
Forgotten Crypts (Deshaan) for skeletons. Vile Laboratory (Cold Harbour) for zombies. Starved Plain outside Davon's Watch (Stonefalls) for ghosts. Cold Rock Diggings (Alik'r) for vampires.

Tip: Hollow Men in Greenheart count as Storm Atronachs for achievement tracking. Farming 100 of them is significantly faster than hunting traditional Storm Atronachs.

What Build to Use

Any competent solo build handles Seasoned difficulty without rethinking your skill bar. On Seasoned, you take double incoming damage and deal half: but overland enemies were not exactly threatening before, so the math still works in your favor.

Dragonknight is the proven choice for this grind: survivability and AoE clear in one package. Templar works too. If you are on a glass-cannon setup tuned for group content, consider slotting one defensive ability before you start. Dying mid-loop wastes more time than any build optimization saves.

Do not use Master or Vestige difficulty. Kills count the same. You will just spend 3x as long on each enemy and occasionally get one-shot by a Scamp in a moment you will never fully recover from emotionally.
