Gearing Priorities
Above you can see the ideal gear you want to aim for. Your first priority while gearing is to cap your elemental resistances, get 40%+ chaos resistance and meet all of your attribute requirements. After that you want to keep getting more Life, Evasion and Energy shield and start improving the damage rolls on your gear. Your gloves and rings provide the majority of base damage for your build, so highly prioritize those added damage modifiers. You can of course have rarity and life on prefixes as well, but the added damage modifiers are your first priority. The last priority are the luxury modifiers, such as crit on helmet and gloves as well as Rarity on most pieces of your gear. The goal is to reach 100-150 rarity, since that is the sweet spot for maximum benefit vs efficiency.
Weapon
You want
Tangletongue with as much critical chance as you can get. Ideally shoot for 23%+ corrupted one, but get whatever is the highest crit you can, at the beginning.
Off-Hand
Sacred Flame is the best off-hand you can use. It provides
Purity of Fire which has no spirit reservation and allows you to have supports such as Clarity and Cannibalism socketed in it, without the additional spirit cost. The only roll that matters on it, is the Fire Damage roll - get as much as you can.
Before
Sacred Flame, you can use an
Omen Sceptre with attributes and increased spirit.
Helmet
Use an Energy Shield helmet to maximize the benefit of
Subterfuge Mask passive. Helmet is a good slot for a lot of rarity and can come with extra crit chance if you need it.
Gloves
Get as much added damage as you can. Critical Damage Bonus suffix is also a great way to boost your damage. Ideal suffixes will have the Crit Damage Bonus, Chaos Res and Rarity, but get whatever useful stats you can.
Boots
35% movement speed is the priority, after that you want as much defensive stats as you can while also trying to get a rarity suffix.
Body Armour
Falconer's Jacket is the best base, due to implicit movement speed bonus. Focus on as much evasion and energy shield as you can as the main priority - then get as much life and resistances with it as you can.
Rings
Both rings should have as much flat added damage as possible. Breach rings are the best base, but any base with a useful resistance implicit modifier is good. Try to get one ring with triple attributes, to maximize the benefits of catalysts which increase attribute modifiers. The other ring should have resistances and rarity on suffixes.
Amulet
Beacon of Azis is a simple solution to all enemy resistances. We deal mixed damage, therefore we need something to deal with all resistances.
Anoint
Stormcharged as soon as you can. You can also use the anoint to temporarily fix your attribute requirements.
Belt
Ingenuity it's one of the only ways we can increase our damage and rarity through the belt slot. Get as high rolls on it as you can. Make sure to get 3 charm slots with it as well.
Mana Flask
In order to get the maximum benefit from the Ambrosia support, you need at least 68% increased mana flask charges on your suffix.
Jewels
Get either
Sapphire or
Emerald jewels, with as many beneficial modifiers as you can. Corruption enchants can also provide additional attributes and resistances that can help you meet your requirements.
