After several attempts to defeat the mother and running out of food due to high damage I came up with a "tag" method which proved to be much safer. Equipment was oriented towards mage defense as I was using Protect from Range prayer. Extra food was located in my familiar. When the fight started I used Balmung initially until the Dagganoth Mother changed defense. As soon as this happened I moved a few spaces away so that the only damage I was recieving was range/mage. This led to the Dagganoth mother hitting a max hit of 14 on me with mage, as opposed to 43 with melee. When ever she changed stances I cast one spell of the particular element, or one dart for range to trigger the stance change. As soon as the Dagannoth Mother turned orange (melee weakness) I charged in with Balmung, and retreated when she changed. I ended the fight with food left over due to the low damage output of mage. In conclusion I believe that mage defense is the preferred armour option as it severley reduces the Dagannoth Mother's damage output.
