Offensive spell Cleric build

[scampb]

Can anyone point me in the direction of an offesive spell oriented cleric build? I just don't want to be a healbot and want to contribute in other ways. If you can post a link to a build, post a build or even just some starting stats with feat/enhancement suggestions it would be appreciated. Human preferred. I have my level 18 Dwarf Barb but I am already missing the mid level stuff that I enjoy so much. So, instead of grinding on a regular basis I am trying to create my own team of specialists so when I get tired of playing one I can switch over to another. I could use one of Sigtrent's builds but unfortunately they only go to level 16 and not being a scholar of the game I would not know what to switch around since all the updates. Please help....and I promise I won't let you die when we PUG together!

click the link in my sig, though the starting stats should be adjusted: less cha, more con
but besides that a very powerful build
