Anomalous object

casting this spell you manipulate the spool of thread stretch out creating a line, then the line stretches into a square, the square into a cube, the cube into a tesseract, into a pentaract, into a hexaract, and so on. as you approach higher and higher dimensions of geometry you inflict damage upon all who bear witness, including yourself.

when this spell is cast all creatures within 60 ft of the illusion must make a DC (16 + spell levels above 5th) intelligence saving throw, forcing the creature to make and maintain direct eye contact with the illusion for the duration of its casting on a failure.

each round the caster maintains concentration on this spell all creatures within 60 ft and making direct eye contact must make a DC (12 + [1 * rounds maintained]) intelligence saving throw, becoming unconscious for (2 * rounds maintained) minutes on a failure and taking (1 * rounds maintained)d6 psychic damage on a success. creatures with an intelligence score below 2, creatures with immunity to psychic damage, creatures who are not making eye contact and creatures who do not have vision or are blinded are immune to this effect. 

if line of sight with the object is obstructed all effects, save for incapacitation, are ended unless eye contact is reinitiated.

if the caster maintains concentration on the spell for its full duration they can choose one weapon within range. the next attack roll made for that weapon will be increased by (1 + (1 * every two levels above 5th)) and damage dealt will be true damage.

the duration of this spell increases by 1 round for every two levels above 5th
