I've changed the shapeshift to (greater) werewolf on the claws so that the type, normally 0, be 1, where the choices are "1 No resistances/statistics gained, spell-casting enabled, colouring", and "2 No resistances/statistics gained, spell-casting enabled, no colouring", according to iesdp. Also, this is using Polymorph into Specific [135]. I checked the big metal unit's ability to shapechange, and all it does is change the avatar to look like an iron golem. Perhaps Graphics: Animation Change [53] might work out better. I suppose I might install the rebalancing as well, and see how that is done...
The shapeshift natural form doesn't work, however, and while the claws are destroyed, the druid doesn't actually revert back into whatever form (s)he originated in. So I'm stuck with a permanent, fully functioning as a human druid looking like a werewolf if I use Polymorph [135]
I'm really not sure why the effect doesn't go away when the item is destroyed... I'm still interested in how Polymorph [135] works differently than Animation [53].
Edit: Hoohah! Animation [53] was exactly what I needed for it to work the way I wanted.
Now, I'm not entirely sure how dispels work, so I'll go ahead and ask. Since I made a brand new item for the Greater Werewolf, can that be dispelled, or will I have to go in and manually edit the dispels for that to work? Or perhaps I can just use the Greater wolfwere claw instead and edit that as well?
Finally, what all is supposed to transfer over when you shapeshift? The rebalancing is ambiguous about this, as it gives the greater werewolf super awesome saves, and yet gives nothing to the regular werewolf. Is thac0 transferred as well? Pretty much the only problem is that if I make the saves and thac0 cumulative, the form becomes overpowered fast. If the saves and thac0 are flat, then the forms are overpowered at first, then become underpowered (except the greater werewolf...). If there are no saves or thac0, then the shapeshifter might be hurting later on for lack of a proficiency, or a +x thac0 weapon. I suppose the 19/21 strength helps out there immensely.
