Zatha'tek, Breath of Corruption — One-Hand drop, item level & who can use it

Epic one-hand from Ula'tek in The Venomous Abyss: item level 289–344 by difficulty. 8 specs can use it — it carries Agility, Crit. Its effect decides more than its item level, so sim it.

why?
Why? · VerdictBuilt from the item level you set (302) against this drop on Heroic (315), whether it has an effect, and whether your spec can use it. GamGem’s rule of thumb, not a sim: +6 or more is an upgrade, within ±5 a sidegrade, −6 or less a downgrade; any effect asks for a sim.

+13 item levels, but its effect decides — item level alone can’t price it.

Equip: Your attacks have a chance to inflict Breath of Corruption, dealing 3,671 Nature damage and rending a Necrotic Tear that persists until death and increases the damage of this effect by 5%, up to 10 times.

What actually changes?

why?
Why? · StatsBlizzard’s item record prints stats at a preview level that differs between items, so the rows compare how each item SPLITS its secondary rating — the share of each stat — not the raw numbers.

How far can it grow?

Why? · Upgrade trackItem level per rank is the gear page’s track table; every rank costs 20 Mistcrests of the item’s own track. A Mythic 344 drop is past the track and upgrades no further.

What does it compete with?

why?
Why? · CompetitionThe season’s other items for the same slot, the same armour and a shared primary stat, at their item level on the same track as this drop. “Different job” means one has an effect and the other does not — our rule.
315 · dropped on Heroic

Its effect makes it a different job from the stat-only rivals — a sim decides here, not item level.

Where evidence disagrees

  • • Item level says upgrade; its effect may say otherwise — only a sim of your character settles it.
  • • The Great Vault pays 318 for Heroic bosses — more than the drop itself (315).
