So far in my fights on Hard difficulty, Ive been relying on a combination of Control foe and Terror to make the enemies more manageable, but the problem is I sometimes need control foe specifically as the distraction and extra damage dealing is a huge help, but at my current level (only 1, never improved it), its not reliable, even against dumb/low level creatures. Its not uncommon for 2 control foe spells to fail in a row.
I wanted to spend on raising it but is it useful? I read few times that improving skills is not worth it and is better to get the first point of a spell only.
Edit: I just remembered that raising the priestly skills of the character will no doubt help this spell become more efficient, but which skill do I raise? there's Priest spells at 13, spellcraft at 7 and magery at 4 (which still needs a point of intelligence before I can raise.)
Any advice appreciated.
