First of all, my english is very bad to write something.
I don't know if I'll disagree or explain, but INT doesn't work in direct heal spells, because INT don't give direct Magic Damage (like STR gives direct physical damage). The magic damage gave from INT didn't showed in magic damage character because just influences the calc for magic damage (like you said).
All heals are influenced by Magic Damage (direct magic damage, INT don't influence direct magic damage, just offensive magic spells), Light Damage and MND.
i dunno about that.
anyway when a Heal crits and most direct Heals can crit. they got an improved via Scad.
and like i said before:
- Every 5 INT adds 1 Skill Critical Additional Damage.
so int affects the Scad which affects the Crit Heals.
isn`t that right?
