Thaelur’s Wonder

Choose one creature that you can see within range.  You transform the creature into a wingless wonder. The transformation lasts for the duration. If you concentrate on this spell for the full duration, the transformation lasts until it is dispelled with either a casting of remove curse or dispel magic. 

This spell has no effect on a shapechanger or a creature with 0 hit points. An unwilling creature can make a Wisdom saving throw, and if it succeeds, it isn’t affected by this spell.

The target assumes the hit points of its new form, and when it reverts to its normal form, the creature returns to the number of hit points it had before it transformed.

The creature is limited in the actions it can perform by the nature of its new form.

The target’s gear melds into the new form. The creature can’t activate, use, wield, or otherwise benefit from any of its equipment. 

The target replaces all of its ability scores with that of its new form aside from its intelligence, which is kept the same as it was in the creature’s original form. 

A creature permanently transformed into a wingless wonder must succeed on a DC 5 Wisdom check to avoid going insane at the end of each year spent in wonder form. On a failed save the creature goes completely mad. The DC increases by 1 for each year the creature has been trapped in wonder form. 

Beings trapped in wonder form do not emit a psionic lash when slain.
