1. If a Warpriest 3 / Druid 4 selects Weapon Focus (Claw) and Wildshapes into a Leopard (medium sized animal) the claws deal 1d6 for Sacred Weapon right? (Instead of the 1d3 that they normally would)
2. If you had the Improved Natural Attack (Claw) feat, would the Leopard's claws do 1d8 for the "size" increase of the Warpriest damage or would it stay 1d6 since the Sacred Weapon damage is higher than what the claws would be with the feat (1d4)?
3. If you gained 4 levels in Druid and then Wildshaped into a Lion (large sized animal) would your claws do 1d8 (large size Warpriest) instead of 1d4? 3b. With Improved Natural Attack (Claw) feat, 2d6 for Warpriest increase?
4. Anything prevent you from using Fervor while Wildshaped? For the "Cast a spell as a swift action" part you would probably need the Natural Spell feat, but for normal uses of Fervor (healing / damage to undead)?
1) yes
2) no, it would stay 1d6
3) Yes you count as large
4) Yes
