I am trying to create an effective construct team. I am happy with the performance of Furnace, Agnon, and Stonefist, and I am happy with Bauble as a healer. But the weak link is that I can't keep Bauble alive long enough. Which type and mixture of defensive runes would you suggest? In particular, how should I mix health, defensive, and damage reduction? I don't need any offence out of Bauble -- just to keep it alive.
