This is how I've got my level 12 character set up right now.
STR 12 (3 boosted)
DEX 5
INT 7
SPD 8 (1 boosted)
PER 6 (1 boosted)
Offensive Rating 115
Defensive 48
While in Cyseal, even with the battle of Bracuus REX, my hit chance was always above 80%. Coming into Lucculla Forest is where the game pretty much went to shit for me. It started off with 70% chance to hit and just continued to go down hill very sharply.
This issue isn't only with my battlemage but also with anything I summon. Old ladies playing bingo are more violent then my summoned creatures!
My 7 in INT was for the minimal requirements to cast fire spells.
I've already got Leadership Rank 1. Adding a point into Lucky Charm only gave me +3 to my offensive rating.
Now that I think about it, my summoned creatures (Armored Executioner, Water and Fire Elementalists, and Spider) all die very quickly. Sometimes only 1-2 hits take them completely out.
What weapon do you use?
Also hit chance of 70-80% isn't that bad...
