Arcane Lazy Eye
As arcane eye, but during any round in which the caster does not concentrate, the magical eye has a 20% chance to sort of drift off to one side, moving 10 feet in a random direction and orienting on nothing in particular, requiring the caster to spend 1 full round reorienting the magical sensor to get a view of the surrounding location once more.
As chaos hammer, but instead of slowing targets, any creature taking damage has reduced speed as though affected by caltrops. Unlike normal caltrop damage, magical healing must equal the damage dealt by this spell to restore the target's movement speed (other cures work as normal; waiting 24 hours, a DC 15 Heal check, etc.)
Chaotic creatures and creatures without feet are unaffected by this spell.
This hazy cloud of heated gas must appear in an adjacent square to the caster at first, but otherwise moves (and can be controlled) as an incendiary cloud. It doesn't provide concealment, though the shimmering distortion causes a 20% miss chance on attacks into or through it.
Initially, it's effects are equivalent to a stinking cloud on those in its area, but if it contacts any flame, it ignites and functions identically to an incendiary cloud, though it retains its nauseating properties.
