I'm quite new to this game and had a few questions about clerics. I know I'm missing the obvious -- haven't been able to track down an explanation of what stats do what yet. ;-)
So my intuition tells me that Wisdom is for healing, but does wisdom affect damage as well?
What determines spell power? Is it best to just stack as much spell power as possible, or is it better to boost specific stats?
Wisdom is everything. Raw SP is also good. Int is also good. When you're level 50 you can worry about min/maxing beyond this but it's simply not worth it leveling up.
It depends upon your build. Intelligence will increase your spell critical hit chance, which means more critical heals. If you go deep into Sentinel and take spells like serendipity, which are reliant on heal criticals, having a high intelligence can be beneficial.
