To be honest, your going to want to get multiple pieces of gear, for different situations.
Bracers, I would go, Eagle 3 /3 with + 9 stam, RFC bracer + 15 SP, 3/3 stam spirit bracers ( Mp5)
I personally, have the BoA mace with + 30 sp, because, it has 15 SP built in, AND with ur Flametongue on that, its just like omg pyew pyew for sp set.
You can use that for a big OMG heal crit,
I also Have a Smites Reaver with + 30 sp on it, for the Hit rating it has, I find it works really well when dancing round melee'ing
I ALWAYS start a fight, with Dawnblade 22 int, but since ur alliance, Start with Evoc blade 22 int, until u burn through the extra int from ur wep, then swap out to your Spellpower wep. Also I generally start the fight with my Forest Buckler ( 7 stam) until Ive burned through that intellect from my 22 int wep and shield.
Once the starting intellect from your wep and shield is gone, swap out to a Spellpower weapon, and you arctic Buckler with MP5 on it.
once you get even further down in your mana pool, you can swap it out for an evoc with Spirit on it. to try and regen your mana back a bit.
Hope ive helped.
