Will a Cleric who has chosen the diety St. Cuthbert get access to the spell Holy Smite? Also, is Crafting Wondrous item a good feat to take for a third level character? And would you want craft wondrous item as a feat on a character that you plan to take Craft Arms and Armor on? Thanks!
Holy Smite is only available if you choose the Good domain from one of the good deities. Since St. Cuthbert is LN, Holy Smite will not be available for his clerics. I usually take Heironius for my cleric's deity when I play a LG or NG party, and take Good and Law for the domains. That way, when the cleric gets to level 7 (Holy Smite and Order's Wrath are 4th lvl spells,) they can craft Holy and Lawful weapons - both are awesome for taking on the CE minions of the Temple. Craft Wondrous Item is a great feat - you can craft stat-increasing items (Girdle of Strength, Golves of Dexterity, etc) and lots of other nifty items. You may want to have 2 crafters (cleric and either a druid or wizard) with both CWI and CA&A, that way you can spread out the XP hits when you craft.
