Hello all. So I was wondering, if I am a spellcaster under the effects of Blink, does the 20% miss chance on my own attacks also apply to my spells? What if I go ethereal just as I am about to release it? It just says it applies to your "attacks" and offensive spells count as attacks for the purposes of other spells like invisibility, so I was wondering if there is a 20% chance your spells happens to rock the ethereal plane instead of the material. Thank you for any reply.
Everything you need is explained in the spell description (at least it does in my version of the book)
"Likewise, your own attacks have
a 20% miss chance, since you sometimes go ethereal just as you are
about to strike."
"Your own spells have a 20% chance to activate just as you go ethereal, in which case they typically do not affect the Material Plane (but they might affect targets on the Ethereal Plane)."
Also note that you have extra protection against enemy spells (50% chance to fail if targeted, half damage against area spells), and there are a few other special rules related to Blink.
