Spells (3e)

The blink effect rapidly cycles the character in and out of the ethereal plane. Blinking has several effects:

Physical attacks suffer a 50% miss chance, and the Blind-Fight feat doesn't help (since the blinker is ethereal and not merely invisible). If the attack is capable of striking ethereal or incorporeal creatures, the miss chance is only 20% (for one-half concealment). If the attacker can see invisible creatures, the miss chance is also only 20%. If the attacker can both see and strike ethereal creatures, he suffers no penalty. Likewise, the character's own attacks suffer a 20% miss chance, since the character sometimes goes ethereal just as the character is about to strike.

Individually targeted spells have a 50% chance to fail against the character while blinking unless the character's attacker can target invisible, ethereal creatures. Likewise, the character's own spells have a 20% chance to activate just as the character goes ethereal, in which case they typically do not affect the Material Plane.

While blinking, the character takes only half damage from area attacks (or full damage from those that extend onto the Ethereal Plane). The character strikes as an invisible creature (+2 attack), denying the character's target any Dexterity bonus to AC. The character suffers only half damage from falling, since the character falls only while the character is material.

While blinking, the character can step through (but not see through) solid objects. For each 5 feet of solid material the character walks through, there's a 50% chance that the character becomes material, with regrettable consequences (see below). The character can move only at three-quarters speed: Movement on the Ethereal Plane is at half speed, and the character spends about half the character's time there and half the character's time material.

Since the character spends about half the character's time on the Ethereal Plane, the character can see and even attack ethereal creatures. The character interacts with ethereal creatures roughly the same way the character interacts with material ones. For instance, the character's spells against ethereal creatures are 20% likely to activate just as the character goes material and be lost.

An ethereal creature who becomes material while in a material object is shunted off to the nearest open space and takes 1d6 points of damage per 5 feet so traveled.
