1st Q . If i cast mislead then summon some minnions will my image be able to exceed the summoning limit? (if they can cast spells that u do at all )
if so i think this spell is better than project image.

2nd Q . The detect invisability spell will this detect improved invisable characters? because the worse thing would be learning that spell when its no use and im up to chapter 5.

<font color="lightblue">AFAIK, Mislead doesn`t let you cast spells: it is designed to be used as a decoy while you regain some HP.

Yes, Detect Invisible, Invisibility Purge, True Sight, and Oracle all cancel out Improved Invisibility; solong as the target doesn`t have non-detection; in which case only the lasting spells will work; non detection is cancelled out in the first round, invisibility in the second. </font>
