How does an arcanist use metamagic?

[Thormind]

Is it like a wizard or like a sorcerer?

Either!

Like a sorcerer, an arcanist can choose to apply any metamagic feats she knows to a prepared spell as she casts it, with the same increase in casting time (see Spontaneous Casting and Metamagic Feats). However, she may also prepare a spell with any metamagic feats she knows and cast it without increasing casting time like a wizard. She cannot combine these options—a spell prepared with metamagic feats cannot be further modified with another metamagic feat at the time of casting (unless she has the metamixing arcanist exploit, detailed below).
