Frost Mage Artifact Weapon: Ebonchill – Legion 7.3.5
This section of the Frost Mage guide explains the best possible choices for the Netherlight Crucible, important traits and relic bonuses, and how to progress through your artifact weapon Ebonchill. This guide is written and maintained by Malon, who raids with <Omen> on Emerald Dream EU; his lifelong ambition is to have the Warlock class renamed to 'Fuzzy Cuddlebears'. Find him on
mage forums. Updated for the latest patch.
Artifacts in Battle for Azeroth
As of June 26th, completing the quest
will further empower your Artifact Weapon, enabling all traits and at least
level 75, further increasing in power over time until the Battle for Azeroth pre-expansion patch.
Therefore, only the Netherlight Crucible recommendations are relevant on this guide page leading up to BFA, as you already receive all Artifact Traits by default. This makes content easier to complete, especially some

Relics and the Netherlight Crucible
is a new feature in patch 7.3 that allows you to empower your relics with additional traits. It has the power to turn a previously mediocre relic into a good one, if you get lucky with the trait options it randomly rolls. For this reason, it's a good idea to always preview a relic's potential traits before you use it or throw it away. Even relics of significantly lower item level have the potential to be better than those of a higher level with the right traits.
There are three tiers of traits for each relic: the first tier adds five item levels; the second tier is a choice between a light or shadow power; and the third tier is a choice between one of three weapon traits. You can only choose one trait from each tier. In order to fully unlock the Netherlight Crucible you will need to get your artifact up to level 75, but you will earn your first light or shadow trait at artifact level 60 (and then get a new trait every three levels from there). Note that the trait options are randomly rolled for each relic, so if you equip a new relic you will have to choose new traits at the Crucible.
Below we have provided a
ranking of the Netherlight Crucible traits for the Frost Mage Artifact, from best to worst. Frost, like other Mage specs, gets the most value from the damage procs like
. For artifact traits, we recommend prioritising those listed as optimal later in this guide, or simply simming yourself - for example, using the new

Disclaimer: These Frost Mage Artifact values can change slightly based on your legendaries, overall ilevel, and talent choices. These numbers were obtained by simulating the recommended tier 20 gear and talents from this guide, using the default Mythic T20 profile. If you have the knowledge, we recommend simming your own relic options since ilevel value isn't a very precise unit of measurement. This is intended to help you quickly make relic and Crucible decisions, but it can never be 100% accurate for every character. Since these values were generated before the Crucible was unlocked, they are subject to change if it's found out they weren't being simulated properly. In such a case, this guide will be updated. With the opening of
