0.4 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/gloves: try to focus on high flat damage, because we have generic pen/exposure, you can get any flat damage (lightning, fire or cold, phys is also fine)

amulet: You'll need 30 spirit total if you want to use Rhoa Mount, %max es is also really strong here.
(If you have a 50 spirit amulet you can also fit in Wind Dancer)

Quiver: Just good dps stats, high flat/bow dmg or projectile speed with crit chance/crit damage

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

Bow: Either a very high DPS gemini bow with tier 3 crit or better (3.1%-5%) or craft the bow I have listed on the character (follow my crafting guide).

Rarity: still really good in 0.3, I would try to hit at least 100% if you want to farm efficiently.

Important: You really want a high a energy shield helmet forSubterfuge Mask and a high evasion body armour for Spectral Ward.

Jewels on tree: Just looking for generic damage: attack damage, elemental damage, movement speed, bonus from quivers, projectile damage, attack speed, etc
Double crit jewels are really potent here (critical hit chance and critical hit damage)

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: Subterfuge Mask.
