Spell Combat: the magus may make a full attack and cast a standard action magus spell as a full-round action. He may lose attack to gain a bonus to his concentration check and takes a -2 to attack on top of it. He must have a free hand and the other hand can wield a light or 1h weapon to use this ability.
Wand Wielder: The magus may activate a wand or staff instead of casting a spell when using Spell Combat.

It's great and all but a couple questions raise:
1) Spell Combat requires a free hand. Does this mean I can't wield a weapon and a wand at the same time?
2) How does the magus use spell combat and staves? Staves are 2h weapons, quarterstaves to be specific.
3) Can metamagic rods be used with spell combat?

I presume you can't wield a weapon and SC with a rod at the same time (must hold the rod), so I was thinking about stuff like weaponized rods and wand chambers.

All target words in the pdf for area effects are of the burst type, which does not go through cover.

Typically, however, area spells are of the spread type. Fireball and Meteor Swarm, the evocation iconics of AoE, are spreads. All fog spells are also spreads.

Is there a spread type of target word? If not, will there be any? And emanations?
