If you're ever in a room (or mixed room) of goblin archers, just pick off the archers 1 by 1 by icebolting them 2 times and defend (sometimes charge 3 icebolt just in case). They will put up their bow and run towards you in melee mode and that's when you get'em! Usually in a mixed room there are only 3 goblin archers and the rest are normal goblins (or possibly poison goblins). I just used this technique when doing G2 Paladin Training Exercise for Barri. Also if a goblin archer is aiming at you and you have a kite shield, just put up defense and it would block the arrows, but if a goblin archer uses magnum shot and you still have defense up, it would wound you a little. If you get aggroed by 2 goblin archers in a 4 switch room and they are standing close to each other, just hide behind the switch and they can't shoot you. That gives you time to charge icebolt (to do that technique i told you about) or send out your pet to smash the goblin archers.
Also if you're in a hurry to finish a dungeon and don't care about getting EXP, just do the room skip technique. A room with 1 chest will always give you a key. The 4 switch rooms can be skipped, but watch out for aggro. Try hitting the 2 switches by the door first in case one of them is the right one and you can make your getaway. The rooms with monsters in it, but has a door that you have the key to is also skippable, just click on the door and run straight through, you usually won't get an aggro and if you do just keep running and they will eventually stop chasing you (one time when I did this, I had ALOT of archers on my tail).
Anyways, that's all the useful technique I learned myself (the skipping rooms was from another person and basically everybody should know this). Hope you enjoy my tips
