There are conflicting paragraphs and statements in the descriptions currently making the power unplayable.
First of all, the Psionic version lasts 10 minutes per level, not 1 minute per level, which is the duration of the wizard spell. (XPH, p. 114)
Second, the Psionic version adds two directions in addition to the "up and down" As follows:
Levitate, Psionic: You move up and down, forward and back via mental support. (XPH, p. 70)
Again, this variation on mobility is repeated in the Complete Psionics book:
Levitate, Psionic: You move up and down, forward and back via mental support. (Complete Psionics, p. 72)
This is actually different from the text of the spell in the PHB, which reads,
Levitate: Subject move up and down at your direction. (PHB, p. 193)
Third, (as if this wasn't enough), while the text of the Psionic Levitate says
"When a psion, wilder, or a psychic warrior manifests this power, the target is the manifester (not a willing creature or object)
So why do they include the
Target: You or one willing creature or one object (total weight up to 100 lb./level) (XPH, p. 114)
in the description?
Was this power just overlooked in editing (i.e., is this a mistake)? I noticed unlike Flight, this power does not allow the user to go left or right, just forward and back, making it 2 dimensional motion.
If I'm reading this correctly, Wizard/sorcerer levitate is 1 dimension, Psionic Levitate is 2 dimensions, and flight/Overland Flight are 3 dimensions, respectively.
How I Interpret it So if i read the Psionic Levitate perhaps as it was intended, The character, and only the character (not objects or others) moves up, down, forward and back at a speed of 20 ft, for 10 minutes per level.
Psionic Levitate is radically different in duration, dimension, and target options from the Wizard Spell.
How would you interpret it?
