First of all, thank you for all the responses and help, & sorry I'll cut bits out of the quotes, but I am trying to save space where necessary.
I think that it may not be grappling, but maybe taking him on in a show of near-insane True Bravery. ........ It would have that dramatic feel to it, and make it so you don't have to be some warrior on steroids with thews the size of mountains to kill him.
Very nice idea! That is a fantastic way of doing it, and much more fitting. Also allows more freedom in how the players could deal with him, which is always good.
....... That said, Beowulf wasn't an ordinary guy. He killed a bunch of nasty monsters before ever tackling Grendel.
Either way, what I find interesting is although Grendel will have supernatural toughness of some kind and be strong fast etc., Grendel was defeated far before the advent of the gun. What would be awesome is if 4 or 5 characters all armed with .50 BMG rifles just tore into him. It's not impossible to kill most monsters without their catch, just difficult. ........
Very true, Beowulf was rather a special case - I could easily see it as a one-shot single player adventure for most RPG systems. As for your solution to Grendel, I think that is what 'Physical Immunity' is for! I'm rather fond of the fact in The Dresden Files it is usually smarts (some might say luck for Harry) over gun-size that wins fights with such creatures, although you're certainly right that would deal with a large portion of monsters. Saying that, if we go with the above suggested catch, a gun could indeed kill Grendel - providing the person wielding it was committing a truly brave act! Sweet.
What if Grendel was created via some Darkhallow-like ritual? There could have been several throughout history though the poem's Grendel is probably the most 'successful'.
Whether born anew, created, or resurrected, the original took time to gain power - nearly a generation if I remember the story correctly. So you could also use a combination of time and sacrifice / murder to expand his powers. Start a bit above the grendelkin and add a point of refresh per murder perhaps. Better yet, require the number of murders to increase exponentially. That puts time pressure on the PCs once they figure it out.
A Darkhallow-esque ritual could indeed be the method by which Grendel is summoned; it'd certainly require a lot of power, hence using a Ley-line as the source. The idea of it happening multiple times is nice, although personally I'd probably have it as the same Grendel, simply multiple occurrences of, but that is just me. It could easily work both-ways.
Awesome. That would give Grendel a good excuse to 'back off' after the initial encounter, giving the party time to regather & try to figure out a way of dealing with this new threat. Having the number of deaths increasing to put pressure on the PCs is likewise great.
Also, again pulling from the original story, have him stalk feastal halls (restaurants) and mead halls (bars), taking the patrons one at a time. For bonus points, have him run a bar, and grab the last patron at last call.
Very nice addition. Would be interesting to think of how he'd adapt to the changes. Glamours would be very useful in such situations, luring people out so as not to alert the mass. Even more interesting would be if someone one (or more) of the character's cared about was taken by Grendel. The possibilities here are ... well, evil.
[Insert The Information From This Generally Very Good Post]
Thoughts?
I agree with effectively everything you said! As for the question of grappling skill, he needs to be beatable by an abnormally (yet not necessarily 'inhumanly') strong adversary (who is probably invoking aspects). This detail is more important if 'grappling' is a form of catch, but could be worked around if it isn't.
Your call on power upgrades is a good one, adding Supernatural Strength & Claws. The rest of the Grendelkins powers look about right; this would place it at 21 refresh. Although, that would be subject to change dependant on how much the Catch is worth, which would seem very little. Thus about 26 refresh.
As for stunts, anything you think fitting would be awesome. Although we don't want to make it over-kill. I'll leave that to your judgement!
Thanks to all of you again!
P.s. Sorry about the long message!
P.p.s. How does one format quotes in such a way as to allow them to be 'scrollable', thus lessening the amount of space they take up?
