Warshaper and weapon grafts and bone knight

[Prelegendary]

Warshaper having morphic body how does it interact with weapon grafts and their enhancements and also bone knights exoskeleton of undeath since itd be all part of the body.

[H_H_F_F]

Weapon grafts that grant natural weapons could be enlarged by RAW, so long as you use a shapeshifting method that lets you keep them (remember that all warshaper abilities only work when the warshaper is in a form other than her own).

Exoskeleton of Undeath does not grant natural weapons, and would not be impacted by Morphic Weapons.

The interaction between exoskeleton of undeath and polymorph / alternate forms might require some adjudication.
