Archer Items

So, I'm trying to make an archer build that maximises the damage I can get from my spells and the amout of times I can cast them, pacifically trying to do lots of damage with my bomb arrow spell for that burst when my friends get swarmed by mobs, my current planned set up is as follows
Kaerynn's Mind
Kaerynn's Body
Clock Leggings
Memento
Clockwork Ring
Clockwork Ring (Yes this is deliberate not a typo)
Clock Amulet
Watch Bracelet

And a Fyrespit for the weapon

I don't know if there is anything better so I thought I would run to the forms to see if there where any better weapons or armour that give good spell damage bonus and a good bonus to fire, water and earth damage. I'm deeply apologetic if this is the wrong place I looked around but found nothing

 

Jester set can give you +300 spell damage

 

Oh wow, Is that raw damage or %?

 

Obviously raw, tripled spell damage wpuld be unfair. Also, look into clock boots and only use clock leggings if you got +2 attack speed and -0 attack speed respectively. Attack speed scales up your spell damage, it is not only for melee. If you plan to wear -attack speed clock pants for their spell damage you will actually be doing less overall spell damage. Wear a third eye and another chest with spell, perhaps soul signal or a chestplate that caters to other aspects of your stats/build to maximize effectiveness
