A shimmering aura takes the shape of a multilegged creature from night mare, instantly leaping into battle against your foes.
This spell creates a manifestation of the dreamspace that attacks your enemies. A dream spirit is treated as an incorporeal creature that has your hit points and the AC you would have if you were incorporeal (it loses any armor bonus or natural armor bonus you have but gains a deflection bonus equal to your Charisma modifier or +1, whichever is greater).
The dream spirit appears where you designate and acts immediately, on your turn. It attacks your opponents to the best of its ability. A dream spirit has a single incorporeal touch attack that uses your base attack bonus plus Dexterity modifier and deals ld6 points of damage, plus 1 per two levels (maximum 1d6 + 10).
As a free action, you can mentally direct a dream spirit not to attack, to attack particular enemies, or to perform other actions. The dream spirit acts normally on the last round of the spell's duration and dissipates at the end of its turn.
If a dream spirit is reduced to 0 hit points, this spell ends. If the distance between you and the dream spirit ever exceeds the spell's range, the dream spirit winks out and the spell ends.
Dream spirits are material in nature, and so are not affected by dismissal and similar effects. They are not subject to effects that affect outsiders.
What is the Dream Spirit's movespeed? Does it move or does it instantly teleport next to the guy you order it to attack?
As a general rule, can all incorporeals fly?
Incorporeal creatures pass through and operate in water as easily as they do in air. Incorporeal creatures cannot fall or take falling damage.
this is from the general description of the incorporeal subtype. Cannot fall, move through water and air just as easily, doesn't this suggest that all incorporeals can fly? Cause moving through water = 3 dimensional movement, equal movement in water and air = 3 dimensional movement through air, and cannot fall = float
