hi , after 1,5 hours i have find 

 

-with certain spell the mage go close to enemy and hit everything ( like with fireball or acid cloud ) this happened when the party is in a small zone 

 

-i not understand why mage/cleric/druid don't cast spell occasionally but instead go in closecombat 

 

-the game cursor vanish and appear the classic window cursor 

 

-godlike don't have the head slot ( maybe is intentional ) 

 

-when ranger use "cripple Shot" enemy are stuck but continue to attack my party member even if they are far 

 

 

I've watched the wizards in my group close with the enemy to melee distance to cast a ranged area affect spell on the target. This means they hit everyone in the party too who engaged the target. I've also watched my wizards run away from the target at the beginning of the casting the spell. This might be a pathfinder problem.
