Warrior/Knight Spammy Thrundacrack Build

Here is my build https://wynndata.tk/s/zsopWt

Yes I have to use diamond fusion necklace and other SP boosting items because this build is a pain to get around all the high SP requirements. I used boreal-patterned Aegis and not Aquarius to give me some extra bulk and its an all around good chestplate.
Still, tell me what you think.

 

Use water powders instead of thunder on Thrundacrack, Curse gives an OP damage boost with your already high damage.
Also I've made this build a while back. From my experience, combining high mana regen and mana steal works very well for spell spamming with high attack speed items. This build can also reach 129 intelligence if you have a 7 SP Reminder.
