I'm playing a sorcerer / bonded summoner. I can give my pet medium earth elemental improved sunder, Weapon Focus, give two more members of the party feats they pick from my list, they all last an hour, and then I start casting my other spells ...
Maybe I've come across a good option for my character, but it seems a little too good, perhaps. That being said, after compiling my list, a lot of these feats aren't going to be useful since the players don't meet the prerequisites, but its still a very good spell for a limited caster like a sorcerer ...
