I want to build a two weapon Drow Battle Cleric. I have came up with tho possible sets of stats

16 Strength
16 Dexterity
12 Constitution
10 Intellegence
14 Wisdom
10 Charisma

This one seems to be the best possible candidate so far, but I really want DPS. So here is another idea,

18 Strength
16 Dexterity
12 Constitution
10 Intellegence
8 Wisdom
10 Charisma.

My question is, can you go that low with your wisdom and still be able to cast ALL of the cleric spells. I know I wont have a ton of spell points but I only need enough to heal myself.
