My favorite oddball template is my main character - a Sword-using Paladin Treasure Hunter. I might die a bit doing level 6s & 7s (well, a LOT, if it's a Tokuno map), but it's never dull.
Next would be my Macer Paladin miner/blacksmith. I mine almost exclusively in Ilshenar trying to spawn paragon ore elementals with Gargoyle pickaxes, and while I rarely venture into Fel, he has offed a few people that have attempted to attack him (no one expects a miner to be 120 Macing, and have enough mana to spam disarm).
