Have a Cleric Of Lethander, great AC, Boots of speed, Big war hammer...

What a buzz saw. Just keep them away from your party. Blade Barrier Consistently dishies out 30 HP to any one that comes close.

Try out Smite (equivalent to fireball), Harm and Slay Living for offense and Shield of Archon for defence against mage spells. Negative plane protection and restoration come in handy against vampires while Chaotic commands are useful against mind flayers. Level 1 Doom is also a plus.

Got any suggestions for me on how to mage a cleric good with weapons? proficient sucks.
