Out of curiosity, as I don't believe I've seen it addressed,

I was curious how Polymorph Self works, from the RP perspective.

If a mage transforms, for sake of example, a Child-

1) Do different mages look the same while polymorphed in the same form, for this sake, would two mage male children look different?

2) Would the child look the same every time an individual mage casted? It was mentioned to me that in the PnP version, the mage had choice of such every cast but I was unsure how NWN mechanics and EFU factored this in.

2b.) Should the mage be able to chose appearance, (rather than knowing simply that it is a different child ) can details change? Hair, weight, eye color, etc.

This is tough, because sadly what you see is what you get with the NWN engine. If you have something specific in mind, don't hesitate to grab one of us and let us know what you have planned so we can help.
