Spells per Day: A divine crusader casts divine spells. She may only prepare and cast spells from her chosen domain (see above). Effectively, a divine crusader has a class spell list of only nine spells (one per spell level).

Unless the Divine Crusader's domain includes Sanctified or Corrupt spells (there are no "Vile" spells; "Vile" is a special type of damage), the DC has no class spells of that type. Domains including such spells are Celestial and Deathbound. The only restriction on casting spells (attained via other classes, or the Divine Crusader's own) is that the DC must maintain an alignment exactly matching their deity's. Sanctified or Corrupt spells can shift the character's alignment immediately upon casting.

A creature can attack with a pair of claws as its primary natural weapon if the creature description specifies that. Each claw adds the creature's full STR bonus. (If the creature has only a single natural weapon it instead adds 1½ times its STR bonus.) A Shifter with the Razorclaw trait can attack with both claws only as part of a full attack action. In that case the Shifter can add other natural weapon attacks with appropriate penalties (-5 to attack, ½ STR bonus to damage), but cannot use manufactured weapons. Any attack with a manufactured weapon is treated as a "main hand" weapon, and any natural weapon attack is then a secondary attack. Two-Weapon Fighting never applies to natural attacks, and "main hand" and "off hand" attacks describe use of manufactured weapons, not natural attacks.

See the natural weapon and manufactured weapons Glossary entries (from Monster Manual) for more information.
