Shattered Kingdoms

What is the difference between the two? The spell is Word of recall.

What was your PE when you casted WoR?

If your PE is too low to cast recall, or if you are in a no-recall area, you will get the message "spell failed." If you fail at casting the spell, you will get the message "you failed."

28% each time, and yes I did have enough PE to recall anyways because I succeeded after and it brought me to 8%
Maybe I was on the edge of being able to do it.

Sounds like you may have passed just after a tick.

Makes sense, its the first time I have ever seen the message, I was just wondering what was up.

Same message you get if you're cursed, as well.

My secondary question to this is what does it mean when you cast a spell (no message appears) and nothing happens?

Is that failure or the spell being resisted? I was not in a 'no magic' area. And the spell is closed to being mastered and cast on myself.

What spell was it? A select few spells are "silent" and cause no message to appear when you cast the words: Among these are airy water and know alignment. The nice thing is that as a result you can cast airy water while drowning, but not word of recall, for example (You get a "Your mouth is full of water!" message).

That might be what's going on?

It was polymorph and change sex. Those have never been silent spells.
