OVERALL: One of the most powerful builds in the game, IMO the strongest build in the game and no one you can get as a companion builds into this well, which is why this gets my top pick for your first source hunter. Period. Strong Early-Mid-End.
How to Play Early Game: you will be using a lot of elemental arrows with a mixture of whatever spells you can get your hands on and normal physical attacks. Remember, elemental arrows NEVER miss, and some such as "slowdown arrow" are super easy to make (oil barrel + arrow head) and happen to work on almost all enemies. Poison Arrow is also an easy one (ooze barrel + arrow head) and when shot at someone on fire will also cause explosions. Give yourself a single point in earth/air/water/fire/witch/expert marksman/scoundrel ASAP and pick up the novice skills teleportation/blitz bolt/bitter cold in air, boulder bash/midnight oil/spider in earth, burn my eyes/flare/wildfire in fire, regeneration/rain/slow current in water, splintered arrow/ranged power stance/ricochet in expert marksman, walk-in-shadows/winged feet/fast track in scoundrel, and oath of desecration in witchcraft. As soon as possible make +1 Charisma gear (Belt= Magical Tooth + Rope, Necklace= Magical Tooth + Thread, Rings= Magical Tooth + Ring Kits) and keep it in her backpack.
How to Play Mid Game: Be sure to pick up "burn my eyes" in fire magic ASAP in town if you haven't already, as this will be needed to spot traps as well as hidden treasure more and more as the game progresses; it has a huge turn count which means you can and should have it cast on your ranger at all times (if you still can't spot stuff be sure to make perception potions [eye + empty vial]). Adept skills to look for are ice shard/mass slow/summon ice elemental/cleansing water in water, destroy summon, summon armored undead decapitator (for its poison immune- an upgrade to the Summon Spider) drain willpower and/or rupture in witchcraft, and finally barrage/farseer/vampiric arrow in expert marksman.
How to Play End Game: you will be primarily fighting from a distance as you will become a glass cannon with a bow and powerful magic. (Why bow vs crossbow? http://steamcommunity.com/app/373420/discussions/0/357284767229948204/ ) You won’t be using nearly as many elemental arrows by the end and basic physical attacks should rarely be used, if ever. Master skills to look out for are Hail Attack in Water, and Rain of Arrows plus Arrow Spray in Expert Marksman and Soul Sap in Witchcraft. Adrenaline should be used to replace Fast Track to make the build even more stupid OP.
