So, um, now I wanna play a werewolf. With crinos form and all.
How would you do that in D&D 4E? Please help, Barastrondo, you're my only hope!
Okay, we only did it up to 3rd level (it was a town militia game, albeit for a town with... history). But I'd probably treat it as a shifter/druid anyway (and predator druid at that; guardian druids can be Beorns if they like), like so:
Wild shape can be used to represent Crinos, Hispo or Lupus form. In Crinos form you can still manipulate objects to some degree, like a gorilla could (I don't think they ban gorilla forms, do they?), but you probably feel the primal rage strongly enough that you don't do it very often. I would consider visually attaching certain attacks to "forms," thus saying that Pounce was something you temporarily shift to Hispo for, while Savage Rend is more a Crinos thing.
The shifter aspect can account for Homid/Glabro. Since I'd keep the idea of the separate forms not really having stat modifiers, to keep things 4e-simple, I'd let the player shift as they like as a free action. When you're bloodied, you probably go Glabro if you aren't already.
The odd man out, of course, is the non-Beast Form druid powers. But if we're borrowing from Werewolf: The Apocalypse (or Forsaken) anyway, why not have a player character be able to call on wolf-ancestors to manipulate the weather or call on nature in other ways? Or you can take the "master werewolf" approach, and assume that these kind of powers are as natural to a big, truly tough werewolf as calling the children of the night is to a master vampire. (Since NPCs have fewer class powers, you could build an NPC shifter/druid "werewolf" with exclusively beast form powers.) Edit: And I guess there are options to choose only beast form powers beyond 1st level, so this isn't even too much of a problem. If you relax the "no more than two of your at-wills can be beast form" restriction, you can avoid this entirely.
The Berserker's Fury (multiclass barbarian) feat would seem to be a must. If we're talking something more daring than simple reskinning, I would probably experiment with letting the player substitute druid "caster" powers with barbarian powers, and letting the barbarian powers use beast form rather than a weapon as a focus.
That's off the top of my head. I'd be astonished if you couldn't refine this even further, though, hong. You have a knack for this kind of tinkering.
