Can a Magus gain an a extra attack every round using 0th level cantrips

[Morrigan]

Is it ok for a Magus to use Spell Combat and Spellstrike with Arcane Mark (0th level cantrip) to gain an extra attack every round?

[NikosBlu]

The magus can use his spell combat with any magus spell, even a cantrip. But he never got an extra attack, he simply can use his "off-hand" to cast a spell with a casting time of standard action or less, with his normal attacks, before or after, but not between.
So, an Arcane Mark is OK, but a Ray of Frost, a Daze or even a Disrupt Undead at more use full, and spammable as any Cantrip.

[Carl Cramér]

Basically, Morrigan is right - the Magus can get an additional attack from a combination of spell combat and spellstrike. The only cantrip wich qualifies for this is Arcane Mark, which really does nothing else but gets this hidden utility for the magus.

[NikosBlu]

Well, that is true. Not very usefull, other than the extra attack of course, but true non the less. Unless you take the Close Range Magus Arcana, where you can use any range touch attack spell as touch attack.
