OneFiercePuppy: Well, you should have no trouble delaying that fight until you hit level 7. You don't need to do it until shortly before you leave the isle, and I was level 8 when I left. So, first of all, go get a level. Each level makes a big difference if you've got your characters designed well.

Second (or first and a half) you don't actually have to fight her if you're a good sneak and pickpocket. So you've got that option.

Third, you're already far enough in the game that you're seeing how much damage enemies d compared to how much you do. That's never going to change, really. Enemies will always overwhelmingly out-damage you in this game, so you need to figure out ways to not get hit. Did you luck out and pull a charm skillbook? That would be a big help. How about getting two or three of your characters to cast Levitate and throw several enemies together and then AoE them down all at once? Those beetles are the biggest threat after the witch, so hit them hard, and early. Maybe you can pick up that seventh level I mentioned earlier, and add a point to Warfare for all your characters. If you use melee weapons *OR* a shield (but especially if you use both), you really need a point in Warfare. Between Bull Rush and Battle Stomp, that's two AoE knockdowns per character. So your mage uses a dagger and shield and only does two damage? Doesn't matter. All you really need is the knockdown.

Radeka ROFLstomped me the first time I fought her, it was just discouraging. I was level five or six. I came back at level seven, with some idea of what to expect, and managed the fight, though one character did die and need resurrected. It's meant to be one of the tougher fights before you leave the island, so prepare. Prepare for any fight that's tough, and you should be able to beat it.

Levrifon: Thank you very much for this very detailed response maybe my characters aren't strong enough as you said because my group consist of :
Geomancy/Hunter for my main character
Lohse is hydro/air magic
The dwarf (I don't know his name in the English version) is a warrior
The red lizard is a sort of warrior also with a big two-handed hammer

So I will level up somewhere else :) and apply your advices, I mark this thread as solved but If I found an easy tactic I will talk about it (like getting back with all the traps but the flying bugs are still anoying)

Thanks :)

Levrifon: Hi everyone i would like to talk about combat difficulty

SPOILER PLEASE DO NOT READ IF THE NAME RADEKA DON'T SAY SOMETHING TO YOU :

I arrived at the part where you fight Radeka, but she has 7 characters + herself , everyone can attack 2 times... how can I defeat them ? everytime they make powerful skills with blood or diseases I can barely defeat 2 opponents before dying ..
I'm level 6 like her so maybe I've chosen bad classes but this area is nearly impossible for me.. When I do damage wow lol it's 19 or 23 and when they attack it's 846848640645465 of damage ! :P

IS it the same for you ? thanks :)
