Do imbuements on weapons increase or convert the damage?

Question

If I add an imbuement of fire/ice/death/energy to my weapon, will the elemental damage add up to the normal damage?

If I hit 100 without imbuements, when I add imbuements will I hit 100 + 10 elemental or will my normal hit decrease and I will hit 90 + 10 elemental?

Answer 1

when you apply elemental imbue on your weapon, part of the physical damage is converted to elemental damage.

so for example, if you have a sword with base atk:50, and you apply powerful frost (50% ice damage), you will have a weapon with atk:25 physical and 25 ice.

so you will kill demons faster as they are weak to ice, you can kill creatures immune to physical damage, but if you face any creature immune to ice, you will deal half of your normal hit.
