with t90 mage and a titan it's pretty much a breeze, stick to blood spells, remember fire cape and dark/silverlight/holy water, summoning help to keep titan spec'ing, especially on tds i find, seems to switch quicker. SS should keep you healed fine throughout. take supreme overload, pray renewal and super antis (or supreme overload salve if you wish to save effort/space), with whatever prayer restore you have lying around. Sometimes you'll get a terrible spawn that's near-on impossible in the time, more often than not it is easy enough though so long as you can kill glacs and tds properly.
