Spells: A threskisphinx casts spells as a 6th-level druid.

Typical Druid Spells Prepared (caster level 6th): 0 - create water, cure minor wounds, detect magic, light, purify food and drink; 1st - charm animal (DC 18), cure light wounds, obscuring mist, speak with animals, summon nature's ally I; 2nd - animal trance (DC 19), delay poison, hold animal (DC 19), lesser restoration, summon nature's ally II; 3rd - cure moderate wounds, daylight, neutralize poison, remove disease.

Threskisphinxes use their spells to avoid combat whenever possible, usually throwing out an obscuring mist or a summon nature's ally spell to distract opponents. Because they eat only small fish, a threskisphinx's natural weapons are generally used only for defense.
