Firstly, I'm not sure why this is posted as a plot. It reads more like am item description to me so I'll rate it on that basis.
A reasonably good backstory that nicely explains how the sword came to be in the king's possession, however I would like to know a little more about the Old World magic involved in its creation.
The sword itself requires some comment. Moderate combat bonuses are fine (pretty standard really) but what really makes it special is the subtle mind-effecting powers (very nice, almost demonic possession here).
The fact that it protects the owner from all mundane harm is perhaps a little over powered. Personally I would replace this with some form of defensive bonus and/or spell (the exact nature being largely dependant on how your favourite magic system works).
Another Plot Hook
Refer to "the Real Story"
In order to save their king, and therefore their traditional freedoms (and possibly also their lives) the PCs must learn how and why the sword was created, and by who (or what). Then they must use this knowledge to find a way of destroying the cursed blade, or at the very least neutralising its effects.
As a plot there's not really enough to comment on here and therefore not enough to rate.
As an item I like it a lot - 4/5 Go to Comment
I like this for a campaign goal, but if you only use this sort of thing for a single adventure, it doesn't play well, because you can't get a real crescendo effect going on. Without the buildup, it's harder to create the necessary atmosphere.
Personally, I've been trying to come up with a decently long campaign goal that will work for all power levels of characters(ie something that can be started on at low levels, and still be good at higher levels). This gives me some ideas in that regard. Go to Comment
I like this one. It has both story applications and tactical ones. While the "first one" is a thing of story and myth, these are now "standard items", enchantments that any mage who has studied might know. Go to Comment
I love when one of my older submissions gets dredged up to to the recent comments section. Why Evil? Quite simple actually, and in a single word, Method. The bone stitched is evil because it is a quick and dirty fix. You want massive muscles, you summon it, get chewed up and slapped back together with big bulgy muscles like you wanted.
The 'good' method would be to train, excercise, eat a high protein diet. In short, you earn it, you dont get it for nothing other than a few scars. Go to Comment
