They fixed the +max damage modifier with patch (Where max damage was added to weapon's damage PRIOR to %ED based modifiers), but does anyone know if it would still do that if you put the jewel in the weapon itself, or does it do the same now?

Also, about the property of "Prevent Monster Heal"...
Is the monster's regeneration disabled permanently if you hit it, say once, or does it get disabled for a certain amount of frames?
