90heuksal/90fire/60cold/60light Higher damage (afaik), more mag def, good physical defense and snow shield, good speed, most offensive one among these. I'd suggest protector. Fire imbue.
90heuksal/90cold/90light Higher phy def, higher speed/mobility, way lower mag def, excellent snow shield. I'd suggest garment. Either only light imbue or both cold and light imbue.
90heuksal/90fire/90cold Higher phy and mag def, slow, pretty much no mobility, excellent snow shield, most defensive one among these. You can choose garment or protector. Either only fire imbue or both fire and cold imbue.
EDIT: These are all thinking for a 1:5 hybrid int.
