Summon spells full round action

[Viladin]

Hiya, I am one of the players Zeth was talking about. Taken from page 213 of the pathfinder core rulebook via copy and paste.
> A spell that takes 1 round to cast is a full-round action.
It comes into effect just before the beginning of your turn
in the round after you began casting the spell. You then act
normally after the spell is completed. <
And the summoner spells say
Casting Time: 1 full-round action.

So when they say a spell that takes 1 round to cast is a full-round action. And the casting time says 1 full-round action...

While I am here I was actually wondering about something though. Summoner again, when your avatar reaches an amount of -hp equal to its con score it is banished to its home plane, and when you summon your avatar the avatar hit points are unchanged from the last time it was summoned. Is their a window where you can use a phoenix down when you re summon or am I missing something here ?)

There is a difference in the two. Both requires full-round actions. But a full-round action spell starts/ends on the player's turn. A 1-round action spell starts/ends on the player's next turn.

If your avatar gets banished, it comes back with full health when you resummoned it. There is no window to use a phoenix down though.
