help building with this 6L unique

what is possible build i can use this chest?

For a spellcaster:
Spark
Controlled Destruction
Lightning Penetration
Culling Strike
Mana Leech
Added Cold Damage

For a Voltaxic spellcaster:
Spark
Controlled Destruction
Added Chaos Damage
Void Manipulation
Poison
Rapid Decay

For a hipster spellcaster:
Ice Spear
Controlled Destruction
Increased Critical Damage
Greater Multiple Projectiles
Hypothermia
Added Cold Damage

For an Attacker (doesn't benefit as much from the +1 level, but I guess you'd want +3 in that case anyways):
Tornado Shot
Greater Multiple Projectiles
Physical Projectile Attack Damage
Increased Critical Strikes
Increased Critical Damage
Item Rarity

Or maybe, if you had, say, a Reach:
Tornado Shot
Poison
Physical Projectile Attack Damage
Increased Critical Strikes
Added Chaos Damage
Increased Critical Damage
