Patrunjelu: Get a character that can use "Charm Person" or any other similar spell. It's my favorite way to fight multiple bosses (as long as there's at least 1 human there). I also recommend Entangle and Sleep. If you have a party full of low level characters that can't take most enemies head on (melee), your spells are your best allies.
Fenixp: Oh yes, entangle and a group of archers is a fantastic way to take on a bunch of enemies. Even a big one.
Unless of course your enemies are archers, then basically you will die just as quick
If i was playing through the first time,, I would grab xar and monty and go right to the freindly arm inn, and pick up your other 2 party memebers.. talk to all the people in the freindly arm.. and start doing quests.. goto beregost, and go into every building you can talk to everyone, and save often.. do the quests they give out in that town, then head to naskal and the mines..
Basically what im saying is try taking the direct path with the story to start with.. and lvl up a bit doing that before you start wandering around on those side maps.. the ones along the road north and south arnt to bad, but still can have some major surprises.. personally though, goto the mines, then follow the main story, to a specfic spot, and then listen to where they send you..
Id stick to that as much as i could before doing exploring off the main root. Once you get to the big city you should be high enough lvl to handel some bigger exploring.. Besides many of the quest you will get then are ones that will send you specifically to the side locations you have skipped.
Grab branaween, she is a great party member.
always have some antidots on you.. and if money permits grab some health potions. (not the blue ones, the pinkish/purple ones, these are a big heal and cure poison, get a few for each party member, before you get to cloakwood. (trust me its worth the cash, *wink )
always detect traps, in buildlings, opening chests, dungeons, even outside in some areas.. If you find one you can bet there are more
Stealth is your friend and scouting is hugely important.. get a theif up around 80-90% asap
knowing whats ahead is highly important to for strats, being able to detect traps instealth, using disarm and pausing quick, then poping back into stealth (using pause so you can do it fast as possible) Is key.
AOE stuff effects you as well as enemies.. dont be tossing AOE spells on your party..
Charm is a great tide turner... Dire charm as well.
summon.. (but dont go crazzy with this, it can quickly become an exploit)
If you wanna try to collect a lot of party members, always keep the 5th slot open.. many are one shot, so if you pass, or leave a party memeber at that time they are gone for the most part.
Another thing, if your low lvl and dont want a party member at that time, just dont talk to them.. talk to them later, they will be higher lvl basically matching yours. (for a list, check out the web for all joinable party members)
thats about all i can think off the top of my head
