I'm making a gun mage and trying for out different attack patterns for the character so far I got.
Fire guns, as full attack.
Sacrifice any level spell and get +spell level enchantment, or giving defending, distance, flaming, flaming burst, frost, ghost touch, icy burst, thundering. vicious or wounding for spell level/per min
Expand 1 point and get +2 enchantment, or flaming, flaming burst, frost, icy burst,distance,nimble shot, returning,shock, shocking burst, or speed
cast a spell. While doing so, if the spell is a ranged touch, cone, line, or ray spell, fire it through the firearm which applies the gun's enhancement bonus to the spell's attack roll or to its DC but your gun can explode on you.
Also if the spell is ranged touch , you may choose to fire it through spellstrike. Doing so allows you to make a normal attack with your firearm applying firearm damage, but also applying the effects of the spell if it hits. It is probably possible to combine these two methods, but with the risk that you gun can explode.
Using spell combat. Doing a full-round action, allows you to cast a spell as well as make a normal attack with your gun.
I think there might be a way to full round attack and while still casting a spell
Have I missed any synergies, rotations or tactics.
