I only can't decide between accurate strike or spell blending heroism
i dont think using my arcane pool is that good as im already hitting on 3's and 6's
i got 36 hours left to craft my +4 belt of giant str so i don't think hitting is the problem. this is why i think heroism is the best buff i can get but its a spell i dont realy feel room for!!
i need to get more pearls for certain!!

Hasted Assault is amazing for those combats when you don't have a haste spell to use. If you're not having problems landing your attacks, Accurate Strike and Spell Blending for heroism are both wasted arcana. All heroism is going to give you is an extra +2 to hit, which is wasted.

[Darkflame]

also +2 to saves wich is not only good to add to hit but also to confirm those needed criticals

heroism is good i know this but i dont know if its better aposed to an arcana wich cost me points to use while i also got arcane acuracy to give me +5 in 1 turn.

i think i answered my own question acurate strike is just not worth it.

if you know a better arcana than spell blending heroism please tell me!!
