# Where are the rules for summoned creatures?

In the PHB1, summoned creatures are very clearly defined in the power descriptions that summon them. In the PHB2, particularly the Invoker powers, I find many summons such as Angel of Fire that do not define all of a summoned creature's attributes, or even how long it persists.

Where can I find this information? Have these powers been errata'd?
