Speedy Summons' duration...

[maouse]

I have a player who has Speedy Summons (from Mythic Adv) and am curious as to the ruling on how long these critters last.

I mean, typically it is 1 round/level...

But does this mean that because he can cast the spell in less than one round that the duration is the casting round PLUS one more round per level? In other words, it comes into being, attacks, then attacks again on the next round, then disappears (level 1)?

The round count starts when he finishes casting the spell so if caster level 1 the summon would disappear at the start of his next turn.

So basically it starts when summoned and works as a the summoned monster's own initiative (and disappears before its next initiative)... Independent of the caster's own initiative, but using the same initiative number. kk.
