Isn't that the Conjuration, rather than Summoning, spell? I thought the point of Conjuration was that it was, for the most part, just another attack spell for a Summoner. That is to say, a Conjuration takes an action (in this case, standard), does its thing, then disappears. It's also an encounter power.Minor action? The summon fire warrior in the preview requires a standard action to give the attack command.
I think the issue is that you're looking at what is basically a fancy fireball spell and trying to read it like Summon Monster I from 3.5.
Wizards aren't doing much with their minor actions anyway, right? Asides from sustaining stuff.
Maybe there'll be a feat where your summons are immune to your own spell effects...
Could you elaborate? I don't have PHB2 and decided early on that I didn't really care for most of what I'd heard about the Primal source, anyway, so I didn't pay much attention.The irony of this statement is that CS makes the same reading on Shaman Spirit Companions....
