You can't even get to the Twilight thorn!!!!!!!! The mysterious bear in desert of souls 4 takes you there... but as we all know.. it's like glitched or something.... only takes your money and doesn't take you anywhere.
Well, monster rather... There is an NPC somewhere in the Desert of Souls (4, I think it was) that, if you select the second option, it should take you to this location called Station of Serenity, where you can hunt the Twilight Thorn.
Beware, it has several thousand hit points, though, getting a little help isn't the worst thing you could do, I think it has a one hit kill spell too, so yeah, definitely shouldn't solo it unless you could kill it real quick, and have a lot of good luck. >.>
Edit: Oh, yeah...that is problematic, isn't it? XP Well, I don't think the weapons are that great anyways...aren't missing much. :/
Not all enchantments have a word/phrase you can enter to apply the enchantment, in fact most of them don't, I think the Fire Soul enchantment is the only one that has a word you can enter to apply the enchantment to equipment. >.>
Right now, I have an enchantment I learned, that I can not use anywhere, but it is really good, it's bugging me...
You do know that they are optional, and you don't really get much for beating them? Pretty much just proof of having beaten them, I have proof of beating each one of them, just from times when I had nothing better to do than defeat them. XP
