Arcane Archer

[Gilcrow]

I am quite new to Role Playing games in general and Pathfinder all together.

A group of us are several weeks into a campaign and I am playing a Half Elf Ranger using a Bow as his preferred weapon.

I am at Lvl 4, and not too far from Lvl 5. I am thinking about aiming for Arcane Archer so I will need to cross class into Wizard soon but I also need Weapons Focus (I have all the other feats for the Bow that are needed for Arcane Archer, is this just another feat that I can choose at some point and is it available to a Ranger

welcome to the game

you can choose it as your one of your feats you gain at odd level.
and feat availability is shown under the perquisites which a level 4 ranger should all ready meet

Welcome Gilcrow.

You might consider taking 2 levels of fighter after your 4 levels of Ranger. Compared to 6 levels of Ranger this will gain you one more feat at the expense of a favored enemy and a change in the weighting of your saves. Go wizard at CL 7 or course, then Arcane Archer. After a few levels of Arcane Archer you'll have the option of continuing with AA or switching to Eldritch Knight.

Have fun.

You also might consider taking Dervish Dancer Bard instead of Wizard for your arcane class. You'll get a free dervish dance feat to let you switch hit if needed, and the double strength self only inspire courage will give you more static bonuses to your arrows. You do loose out on the more blasty spells for imbue arrow, but you still get great self buffs and some light healing.
