I'm playing NWN enhanced edition. Pretty basic ass game so far but fun enough

Anything I should know about going cleric? Right now I do almost no damage and can hardly tank. I let my summon pet and companion so all the work while I buff them and then go sift through barrels. It's annoying how every ches to have to wait for companion to unlock.

I'm worried cleric is boring high level because the fun I see in nwn is reaching level ten spells which in other dnd games you only reach like level six. Is nwn 2 better?
