Okay my questions relate to beginning levels of Split Arrow (1 thru 15) because I know support gems can be added later to help out.

(1) Now as list it the description above it shows Split Arrow as Attack and Bow primarily. I know it fires multiple arrows so why isn't Projectile listed??? I would think that each arrow fired is considerd a projectile, so one would think I should get Projectile nodes on my skill tree along with Attack and Bow nodes.

(2) If I get Chaos nodes will they also help the Split Arrow? Or do I need some sort of Chaos gem or Jewel for that later on as I level up?

(3) I would think the following are my best Support Gems for Split Arrow (for level 7 thru say 50).

Mana Leach (if I notice I am eating up a great deal of Mana) with my support gems.
Faster Attacks
Faster Projectiles
Culling Strike
Iron Grip
Pierce
Life Gain On Hit

If there are any other support gems (Under Level 55) that you think i need would you please let me know in your opinion why I need these other gems.


Thank You for the assistance.

1. All gems with the Bow property are directly assumed to be Projectiles unless otherwise stated.

2. You need to have a source of Chaos Damage, i.e Added Chaos Damage, Poison, etc.

3. Depends on your build. Conversion builds are still a thing. But:

Culling Strike is never needed (it's purely a quality of life support)
Mana Leech can be offset with Leech nodes or Elreon Jewelry/Praxis
Iron Grip is weak unless you have a high amount of Strength
LGoH is fine, but you can get by with Leech instead

Look for damage increases for leveling. Added Fire Damage, Faster/Slower Proj is fine, Phys to Lightning is a thing, Weapon Elemental Damage is good if you have a decent source of Elemental Damage, Pierce (If you Pierce, you can't Chain), Faster Attacks, Inc Crit Strikes if you're going crit, etc.
