I am a new GM who has formed a group and am trying to run it to my best abilities. I have a few questions when a caster casts a damage spell to they make a hit roll vs the enemies touch ac? or full ac? or do the enemies get saves toward the spells. Also do sorcerers add their charisma to all spell damage? or no also starting lvl 1 weapons one of my players is playing a tiefling barbarian and he is using a 2h bludgeoning weapon but it does 2d6 of damage so on a lvl 1 encounter he almost always 1 shots everything compared to the others. The weapon is called a earth breaker. Should be rationing out what weapons they can have even though they can afford it for balance sake? Because as it is the casters will get s~** on by lvl 1 encounter monsters. But the barbarian can take all the hits and deal a killing blow almost every round. What should I do ? Also do you always add str mod to melee hits? also how does the combat maneuvers work like charge? or grapple I haven't been able to comfortably explain that to the players yer

I've really just dove into the Pathfinder system. I have no background in RP games but in a odd decision when I came across a comic shop I BOUGHT ALL THE BOOKS. All hard back copies of the Paizo 3.5 OGL w/e Pathfinder books. I have read through the Core Rulebook, partly through Ultimate Magic , Combat and the APG. From there I made a character and found a Pathfinder Society group by chance. Which then turned into I have a 6 man group on Sunday which I GM. I've ran 2 adventures and I feel they've done good. BUT I have concerns as a GM. MY concerns are I don't have a firm grasp on the rules because I haven't played enough to get everything I should.Like when a PC cast a spell does he Roll a D20 or do I roll a Will save for my monster? Then with spells like burning hands it says 5d4 max. But no damage that seems reasonable is it like 1d4 per level? Or the DC's of all the basic spells like bardic spells. Also there is a Gunslinger in the group lvl 2 but I think his character is a bit rigged and am unsure if he is cheating or not. The thing in question is he got a double barrel pistol can he use a full round action to use both barrels to hit? Also the critical threat is x4! Can a gunslinger start with that gun as a battered version? and repair it? Also can Lvl 0s be used as much as they want per day. Also how to figure in bonus spells for each class or what reference to use. Also if any one can give me general monster tips?
