I am thinking of playing one in an upcoming game. It seems fun but I am not so sure on the tower shield it is affordable at low level but it takes away from your ability to do damage especially at lower levels. What I got so far is Marytr and Good blessings race either Human or aasimar. I am completely lost as to what feats to take. I don't see any way to remove the -2 to attack from tower shield as I said so I don't know if it is worth going down that path. I was thinking Divine favor and cure light wounds as prepared 1st level spells. 15 point buy is what I think the game will have so in order am thinking 15,12,14,10,14,7 Aasimar making the wis as high as it ever needs to be before items and making the dump cha less bad. If human probably still put the stat in wisdom to get more uses out of fervor at 2nd.
