I don't remember where and when I first heard or read it, but I distinctly remember someone once telling me that talking magical weapons in a D&D setting were pretty much always bad news. This memory keeps coming back to me every time I encounter one, but Neverwinter seems to be set on defying my expectations.
First there was the Sunsword in Ravenloft, whose pride and OP-ness made for - in its own words - "a superlative experience".
Now, in Undermountain you find another talking sword in a green dragon's lair. After you beat the dragon, it urges you to use its blade for the finishing blow. So you stick it into the dragon's head... and the creature rises again, with the magical sword now effectively controlling the dragon's mind and body.
Then you spend the rest of the zone with a dragon buddy helping you fight the baddies.
Not what I expected.(Also, obligatory Bloglovin link so I can add the blog to my list there!)
