Alright. Where are you right now?
Because normally, if you start a BG game you start with something 'easy', so a Fighter.
You go through the tutorial, do EVERYTHING, you'll need the stuff. Then head outside with Gorion, watch cut-scene cry manly tears.
Then take Immy and head to the FAA (No not that FAA), collect Jaheira & Khalid, buy a Stone to Flesh scroll, (You'll need it for your cleric, who doesn't have a side-quest!)
Then go Bandit hunting, use tactics, so place Fighters, Khalid/Yourself, up from, Jaheira to Heal/Buff/Fight as well. And equip Immy with a Bow, stealth her, have her tag one of the bandits. Lure him back. Kill him, rinse & repeat. Level up to.. about 4/5, then go south. If you recruit Minsc, make sure you're strong enough for the Gnoll keep because it's hella hard if your not strong enough yet. Even so, same tactic, hit & lure back.
