Spontaneus Casting and Metamagic

[Liko87]

Can I apply metamagic feats to a spontaneous cast, such as extend the druids' summons?

[Kierato]

Yes, but it takes a full round action to cast.

[cwslyclgh]

since summon natures ally already has a 1 round casting time, when cast spontaneously with metamagic applied it takes an extra round to cast (giving a total of a 2 round casting time to a spontaneously cast extended summon natures ally) See the Core Rulebook page 113, middle of the first column.

[Kierato]

Ah, forgot about that, good catch.
