0.3 Fubgun Lightning Arrow Deadeye

Make sure to fill out your resist, you want 75% fire/cold/lightning resist. Chaos resist is good, but not mandatory to have 75%, I usually aim for 30-50%.

Rings/glove: try to focus on high flat damage, preferable lightning/phys.

Weapon: You want the highest dps ele/phys weapon you can afford, preferable on a Gemini Bow base. Preferable it should also have +4 to attack skills, you can craft this yourself with an "essence of battle". If your bow is 6 affixes, it will only remove a suffix (so your prefix mods are sage).

Quiver: Just good dps stats, high flat/bow dmg or projectile speed with attack speed/+2 proj.

amulet: You'll need 30 spirit total (50 spirit if you want to also use Wind Dancer) Try to get also get % maximum energy shield.

Chest: you want the highest evasion chest you can afford, preferable with deflection on suffix.

Helmet: You want the highest ES helmet you can afford, this gives you majority of your ES and provides great value with Subterfuge Mask

Rarity is still really good in 0.3, I would try to hit at least 100% if you want to farm efficiently (don't focus on this if you feel like you're lacking damage or defense)

Jewels on tree: Just looking for generic damage: attack damage, elemental damage, movement speed, bonus from quivers, projectile damage, attack speed, etc

Boots: Aim for 30% MS with deflection on suffix, life or hybrid es/evasion are both good prefixes.

Attributes: You'll most likely need str on belt and high dex or int on one pieces (you only need 163 dex, after that you should allocate all of your small attribute nodes to intelligence for requirements and than strength).

important:
You'll want 1 sapphire jewel with mana on kill to sustain mana during mapping.
If you want to completely solve mana, you can take Walker of the Wilds and get mana leech on ring or gloves.

Anoint:
Damage: Subterfuge Mask
