This spell seems to be broken as of the new spell changes. I have an item that casts it; there is no effect. Relogging didn't help, and letting somebody else try using the same item themselves also didn't do anything. In addition, I asked another character to cast the actual spell and they told me it also had no effect.
Thank you for your report. This will be fixed ASAP.
Should be fixed.
It was functioning fine yesterday, actually. Thank you.
The duration from a vile (cast at level 5) is about ten seconds at most. This doesn't seem correct.
The item I have that casts it is also at level 5, and it now lasts exactly as long as it did before the spell update.
I'm fairly sure that your observations were mistaken, VP.
I tried it 5 times just an hour ago with potions of retreat (5). They last about 10-15 seconds at most.
Tested again, 11 second duration on potions of retreat (5).
