The best covenant for a fire mage is Venthyr for raiding, and Night Fae for Mythic+ content.
Night Fae’s signature ability, Shifting Power, provides the cooldown reduction needed along with kindling to make Combustion just above a 1-minute cooldown, it usually ends up being around 68 second cooldown on single target with no movement. Additionally its a big source of AoE damage and will be used inside combustion on AoE.
The other ability, Soulshape, provides more mobility to an already extremely mobile class.
Venthyr fire mage is also a super strong alternative, however the build has a lot of RNG because you play pyroclasm paired with sun kings blessing legendary. This build requires multiple instances of standing still to hard cast pyroblast. However, venthyr fire mage is actually slightly stronger on single target than the night fae counterpart, but venthyr falls behind on mutliple target fights. The main upside of venthyr is the fact that you can play all 3 mage specs. Venthyr is super fun if you get a lot of procs, unlike night fae which is very straightforward and has no real change in gameplay at all, venthyr’s gameplay is super engaging but again its all RNG. Venthyr being frost mage best covenant, fire mage 2nd best and arcanes 2nd best, definitely makes venthyr a super flexible covenant choice all around.
Soulbinds and Conduits
Night fae soulbind for single target
Night fae soulbind for AoE
Venthyr soulbind for ST
Venthyr soulbind for AoE
In 9.1 you will unlock a third potency slot, which you will have to swap depending on the content you do. Master flame for AoE, which almost negates the entire flamestrike nerf in patch 9.1. On singlet arget you want to play controlled destruction, which is a nice damage boost but won't affect the nerfs fire received.
In Patch 9.2, we are getting access to a new legendary, our covenant legendary + one additional legendary of our choosing. Sinful Delight as a Venthyr Fire Mage is extremely powerful and has a nice synergy with our toolkit. The best Legendary for a Fire Mage is Sun King’s Blessing for both M+ and Raiding situations. Heart of the fae, for Night Fae will be a Strong pick for Mythic+ content combined with Disciplinary Command. However, it is less viable to play since fire as a spec is mostly oriented around Single Target, so it’s more recommended to play sun king’s blessing and fill the Single Target Role.
These two Legendaries together will provide you with serious damage inside the combustion window once you get your 4 piece tier set. You will gain many Fire Blast charges and Phoenix Flames into Flamestrikes on top of the higher uptime on our conduit Infernal Cascade. This results in a scary damage output throughout our combustion window.
Sinful Delight will be our go-to as a Venthyr Fire Mage combined with Sun King’s Blessing, which is mainly strong on single target damage. However, many fire mages play with sun king's blessing to fill the role of single target and prior damage when they are in a group with heavy AoE classes such as destruction warlocks and survival hunters.
I recommend crafting Sun king's Blessing on Wrist with Haste and versatility or haste and mastery, depending on your stat sims.
As far as unity goes, I'd recommend simming what the best slot to craft it on because it depends on your gear and what pieces won't conflict with your tier pieces, so you don't break your 4 piece.
I'd recommend crafting unity on the belt or a ring if you want a default choice. If you are multispecing and playing the other specs then the ring would probably be the best slot. However, boots can be fine, but you will lose a socket on the ring but gain main stat on boots.
- 2-Set - Fiery Rush - Increases the duration of Combustion by 4 sec.
- 4-Set - Fiery Rush - causing your Fire Blast and Phoenix Flames to recharge 50% faster.
