Blink is a level 3 transmutation spell. This spell allows the spellcaster to travel to the Ethereal Plane, becoming temporarily unassailable and unseen until they return.
Description
At the end of your turn, roll a d20. On 11 or higher, you vanish into the Ethereal Plane. While there, you can't be harmed or seen in this world.
When you do vanish, your presence here is a representation of the location you'll come back to. You can choose to teleport it up to 6 m / 20 ft.
At the end of each turn, there is a chance the affected entity gets Blinked to the Ethereal Plane, where it can't be harmed, seen or affected.
While in the Ethereal Plane, the entity can't move or interact with anything in the world. It can only choose to teleport up to 6 m / 20 ft. When combat ends, so does this effect.
Despite purposely ignoring the functor which breaks Concentration, a StatusGroup error still breaks Concentration when vanishing.
When vanishing into the Ethereal Plane, equipped items are temporarily disabled which will cause item technical statuses that include OnRemoveFunctors (such as those used by Markoheshkir) to trigger, removing any effects provided by those items.
