That's true, I hadn't thought of leggings. It had been suggested that a heavy armor chestpiece was a good way to go since it provides the most protection in one 'piece' of armor, but I have a style for this character ( I don't roleplay specifically but I do like to give them a particular 'feel') and I want to find a dark/forbidding robe if I can.
My magplar is wearing a hidden heavy helm with all the rest light. Not chest but pretty good and not seen. That said, she plans to go to 7 light as she actually wants the magic bonuses more than the heavy/undaunted bonuses.
