Old School informed GURPS Dungeon Fantasy gaming. Basically killing owlbears and taking their stuff, but with 3d6.
Got mine too. That troll needs GURPS stats since it would be a waste not to have him kill a few PCs.
I fully support this notion, even as someone whose PC might actually be one to run into this thing and get wrecked. Heck of a visual.
As Adersonian troll from DFM1, with SM+2, ST and HP +10, peripheral vision, 1extra bite attack and compartmentalized mind?
That's a good start, although you'd want Extra Head instead of Peripheral Vision. Compartmentalized Mind is optional - depends on if you really need to charm both heads to control it, for example. Otherwise Extra Head has that covered pretty well.
I think charming one head could get it into a fistfight with itself...
If you play the "two heads will argue" type, then yeah, you'll need Compartmentalized Mind. Of course, that potentially makes them much nastier, if they find some mental power to use.Personally, I find the "make the heads argue" thing kind of funny but not enough to implement it. Too much "three headed giant" from Holy Grail and not enough power addition for the multi-headed creature. Instead of making multiple heads an advantage, it makes it a serious weakness to be exploited, and I'm adding the extra heads to make it stronger, not weaker.
