I really want to play through the entire trilogy as a Cleric (or variant). When I first played Baldur's Gate almost twenty years ago, I had very little understanding of the D&D spell system, and mostly used the Cleric for healing. Furthermore, I (foolishly) thought of Clerics as being weak, since my initial exposure to "healers" was from the white mages in the Final Fantasy series. It wasn't until Neverwinter Nights that I realized how badass Clerics are, not to mention having a greater understanding of the spells. Also, I would later discover that the class was actually conceived by the game designers as an undead hunter to combat another player's vampire PC, and was inspired by Peter Cushing from the Hammer Horror movies (which is awesome, and hence, Turn Undead has always been a signature ability).
Anyway, I recently started a LG Human Priest of Lathander (16/9/16/13/18/15), and am considering taking him up to level 40 throughout the trilogy. However, a Fighter 6/Cleric 39 would certainly be more powerful with 2 APR (Although Boon of Lathander stacks...), better HP, a better THAC0, weapon mastery, and more items to use. That's a lot for only the loss of one Cleric level. This got me thinking of other potential characters, such as:
Priest of Lathander/Fighter
Priest of Lathander/Thief
Priest of Lathander/Mage
Archer/Cleric (slings, obviously)
So for you Cleric lovers, what was your favorite build, and if you dual class, at what levels have you done so? If you played a pure Cleric, did you later regret not incorporating other class benefits?
