Celestial Stride

Momentarily enveloped by a silvery-white aura, the caster takes on an ethereal appearance, the figure becoming transparent as they ascend into the sky. For the duration of the spell, the caster’s movement speed is quadrupled, and they have advantages on all stealth and investigation checks and dexterity saving throws. Meanwhile, all attempts at seeing and attacking the caster are at a disadvantage.

 While the caster is resistant to all physical damage (such as bludgeoning, bashing, piercing, slashing,  falling, etc...) they are accordingly resistant to magical effects as well, except for psychic for which they take double damage. Accordingly, all magical attempts are limited to spells of a somatic nature (examples include, but are not limited to control flames, true strike, mold earth, thunderclap, Counterspell, etc…)   

 While the spell remains active, the caster can resume their original state at any moment. Upon its official completion, the caster will descend almost instantly from the sky in a manner akin to a shooting star, briefly flashing with a silvery-white light once their feet touch the ground—unharmed.
