I'd go with a cleric who wields a Quarterstaff (I think this would work for Ilmater).
I'd use the spells Spikes, Divine Power, and Divine Favour.
Also as an aside. I was under the impression Divine Metamagic took 1 turn attempt +1 turn attempt/level bump of the metamagic feat.
So for Quicken I thought it was 5 turn attempts.
