Yeah, but Lycanthropy is actually Wolf specific. Extending it to other Species of animals is not the original idea. Lykos is Greek for Wolf after all. so The Full Moon idea comes from the idea of wolves howling at the moon and stuff.
Lycanthropy in general use is also commonly used to refer to *any* were-animal, even if the correct term is "therianthropy". The *origin* of the term is for the Greek for wolf, but it's certainly not the only use.
And while a "true" lycanthrope may only have its full powers for ~2 months worth of days per year, they're at least spread out. It's much easier to weave a game around them. It may be fine mechanically, but make sure the character knows what they're getting into if they're going to have extremely long periods of game-time of weaker-than-human status interspersed with periods of super-human cool-ness. I know I for one would just not enjoy the character.
The major problem with silver is that (like DMW said) in the Dresdenverse the Lycanthropes or any other breed of werewolf (except the loup garou) is NOT vulnerable to silver. Not more so than anyone else at any rate *g*.
Agreed. I actually am allergic to silver (funny how that works, huh?) but I'm much more scared of being hit over the head with a silver candlestick than having silver dust thrown on me.
I guess in my head I was kindof mixing "arkanthropy" with "were-bears". As you correctly pointed out, lycanthropy - as handled in the Dresdenverse - is a special case of wolf were-form where a spirit of rage is affected by the lunar cycle and its strength cycles with the moon... While a completely different form of were-creature (loup garou) is affected by silver.
The fact remains, in my head, it depends on the source of the arkanthropy. If it's a curse, I stand by my "silver" comments. If it's a spirit, probably not so much.
