Just a tip to beware of your own flaming sphere if it is still active after combat ends. As it functions like a familiar, it will automatically roll up to your group when combat ends as your party regroups and may torch a few members of the party in the process if they happen to end up standing near it or get in the way as it beelines for the person who cast it. It doesn't discriminate between friend and foe and will set anyone on fire who gets too close.
Well now I've heard about friendly fire but this here would suck if it's your party. Thankfully I re-rolled my Rager knight as I wanted to see if they fixed some of the feats and weapons for which she had. But just played the game 1 day due to work and I've only gotten to level 3 currently.
