I figured out why the plant in the swamp is so hard. It's no ordinary tentacle-plant-thingy, it's a boss-type plant-thingy, meaning it's extra tough and gives a special trophy when you kill it. Quite a tough fight to be honest, but I didn't have to use any potions to kill him, so I suppose it wasn't *that* hard.
I've already asked the nun, and she says "berries, fruits, plants" or something similar. I've tried giving the statue all sorts of plants and what not, but all items are just greyed out when I select the statue (meaning they can't be given to the statue).
Are there three statues? Thought there were two, one in the hospital and one in the swamp. If there are three, then I only need one other except the three (from the main suspect I suppose).
And yes, getting some sleep makes it quite a bit easier. At work right now, but after I got The Witcher on Saturday I didn't sleep a whole lot to be honest. Very captivating, even with its flaws. I am beginning to wonder what difference the various talents make though, my character seem to become such an all-rounder there is little need to get other talents. I suppose it's possible to go more for magic than melee, but everything is needed to a certain degree it seems.
