Kunaix:Karu Forest isn't too annoying as Peaca
but it's still not easy
Strange comparison you put there.
I'd compare Karu forest with a harder version of Ciar, really.
The mobs include things like Masked Goblins, and Masked Goblin Archers. which are basically goblins with a little too much hp. The only harder part of this is the fact that...
1. There are two different types of Masked Goblins, armed and unarmed, each setting their own aggro counter. I think...
2. They have more health, like I said. The archers don't drop as easily, making it a bit harder.
3. They go intangible every once in a while, so you can't hit them anymore. Its a lot like Elf's "Hide" skill. And when they show themselves again, their hp is restored. If you're not pulling wound damage, this dungeon can get a bit difficult.
The other mobs are Stone Spiders, which are basically like... Laghodessas (or however nexon spells it these days). I think the aggro limit is 2 or 3. You'll see lots with titles, giving more power and hp. They also do the intangibility thing.
Stone wolves, are basically skeleton wolves with more hp. They also do the intangibility thing. Heck, all the mobs in here do.
Stone imps are DANGEROUS. Long aggro range, powerful attacks, lots of hp, multiaggro, and usually come out mixed with other mobs.
Stone Bisons are DANGEROUS. They're like Gorgons with more hp and no PD.
Stone mimics are laughably stupid.
Stone Zombies are DANGEROUS. They're like regular zombies, but heres the catch: Intangibility Hp Restore. If your windmill or smash attack doesn't kill them, they'll just get all their hp back.
This dungeon, in general, is pretty easy until the last floor. It shouldn't be compared to Peaca at all. The last floor spawns bisons, imps, and zombies on you, and that takes a bit of skill, but otherwise, its basically like a mix of Ciar, Rabbie, and you just pump their hp a bit.
Of course, Shining Spider pass makes the mobs stronger... but thats beside the point.
What you have to watch out for is Maize dungeon. THAT is comparable to Peaca, what with slate fighters being overpowered in every stat possible and wussed down versions of ghosts spawning left and right.

Hauu Hauuuu~~!
