I started a "turtle" build recently. It's enjoyable. Not as all powerful as my vampire fearmancer, but really a good build for DID (dead is dead). Level 24 and haven't died yet. He wears heavy armor and employs blocking to the extreme. Upon being threatened he retreats into a protective shell. He casts three layers of wall spells around his body, wears a cloak spell, summons an atronauch, sits on a rune, and holds his shield up high. If enemies aren't being proactive enough about coming after him, he will force them into battle with a frenzy spell. Also charges shouts like fire breath and frost breath to pop enemies that aren't dying fast enough.
'Kilgore Trout once wrote a short story which was a dialogue between two pieces of yeast. They were discussing the possible purposes of life as they ate sugar and suffocated in their own excrement. Because of their limited intelligence, they never came close to guessing that they were making champagne.'
