[Theorycraft] Shotgun Duelist

Hi, I recently started playing hardcore and this is the first build I came up with. The idea is to use Chin Sol and Point Blank with Ice Shot to imitate a shotgun.

Passive Skill Tree:



Gear:
Weapon - Chin Sol
All the rest - prioritize Life>Elemental Resistances until capped>Armor>Evasion


Skill Gem Setup:
Damage - Ice Shot + Slower Projectiles + Lesser/Greater Multiple Projectiles + Pierce + Knockback


Defense - Cast when Damage Taken + Molten Shell + a curse + Immortal Call


Auras&Buffs - Enlighten + Clarity + Arctic Armor + some other aura/buff


Utility - Blink Arrow + Enduring Cry + Phase Walk + Faster Casting


Panic Button - Higher level Cast when Damage Taken + Decoy Totem + Phase walk



I'm still a casul and don't know if this needs mana and/or life leech or something else

Point blank and knockback gem doesn't make sense. You do less damage the further enemies get. If you get more than a 1/4 of a screen away you will actually do LESS damage.

Also your better of getting life/mana leech from rings/gear because ice shot still does 50% physical. Clarify is a waste of reserved mana better used for hatred

Also your single target dps will be low with pierce linked.
Best single target with Chin sol is trap + point blank gem + puncture + Physical projectile attack damage.

There was a Shadow build thread called 'Railgun' that focused on this same interaction - Ice SHot, Point Blank, Chin Sol. This one, methinks: Shadow Railgun. It'd have more information for you, though obviously the wrong start. Maybe that would help?
